  Kohler Governor Cross Shaft Bushings with Rubber O-Ring to
Prevent Oil Leak. Rubber O-ring fits snug in bushing and on cross shaft,
and has no effect with movement of governor leverage whatsoever. WHY HAVING
THIS O-RING INSTALLED IS IMPORTANT: On single cylinder Kohler engines, vacuum
within the crankcase created by the upward stroke of the piston draws in
a small amount of outside air, along with a small amount of dust, dirt and
debris through the governor bushing and shaft, pressurized air within the
crankcase created by the downward stroke of the piston blows out a fine mist
of crankcase oil through the bushing and shaft. Overtime, the dust, dirt
and debris of this repeated pulsating action will, without a doubt, cause
the bushing (and sometimes the shaft, too) to wear, which causes a thin film
of oily mess to exist on the outside of the engine block. IMPORTANT INFORMATION
UPON REMOVAL OF THE BUSHING: When removing the old bushing, use caution to
prevent the governor cross shaft from pulling outward and possibly falling
down inside the crankcase! If this happens, the entire engine
must be completely disassembled just to reinstall the governor cross shaft
in place. Also, before installing this bushing with the O-ring, apply clean
oil inside the bushing and O-ring and/or on the shaft for lubrication. With
no prior lubrication, the dry bushing and rubber will eventually wear dry
from friction, possibly causing a new oil leak. Do the job right the
first time, and it won't have to be done again for a long time.

for Kohler engine models K241, M10, K301, M12, K321, M14, K341 and M16 used
with an air compressor, generator and/or welding unit. Also ideal for
use in a 4,000± RPM competition pulling engine. Recovers engine RPM
quickly when under a load and maintains engine RPM at a more steady pace.
IMPORTANT: Apply oil or grease on stub shaft to prevent wear or damage
to governor gear assembly upon engine startup until crankcase oil reach this
area.
 Cast Iron Governor Gear Assembly
with
Symmetrical Flyweights. Fits Kohler engine models K141,
K160/K161, K181, L160/L161, L181, M8, K241,
M10, K301, M12, K321, M14, K341, M16, KT17 (first design), KT17 Series II,
KT19/KT19 Series II, KT21, MV16, M18, MV18, M20 and MV20. Recommended for
high RPM or
wide
open throttle competition pulling engines. Will not become distorted
or explode at high RPM or at open RPM like the nylon governor gears sometimes
do. (Kohler never made a steel governor gear.) IMPORTANT: Apply oil or
grease on stub shaft to prevent wear or damage to governor gear assembly
upon engine startup until crankcase oil reach this area.
Thrust Washers for Governor Gear Assemblies. Fits Kohler engine models K241, M10, K301, M12, K321, M14, K341, M16, K361, KT17, KT17 Series II, KT19, KT19 Series II, KT21, MV16, M18, MV18, M20 and MV20. A thrust washer is required to prevent the governor gear from wearing against the engine block when the governor gear is under full pressure from the engine running at higher RPM. Many people are not aware of the thrust washer because it may appear to be part of the engine block, and it usually falls out and gets lost while cleaning inside the block. IMPORTANT: Apply oil or grease on stub shaft to prevent wear or damage to governor gear assembly upon engine startup until crankcase oil reach this area.
Governor Gear Stub Shafts. NOTE: Install each stub shaft listed below until .345" (11/32") protrudes from the block, and apply oil or grease on it to prevent wear to governor gear assembly to prevent a dry engine startup until crankcase oil reach this area. FYI - All OEM Kohler stub shafts that originally come in the engine are smooth the entire length. Only new OEM replacement stub shafts are knurled on one end. Therefore, perhaps the OEM stub shaft can be reused by reinstalling it in reverse if the worn half fits tight in the block. Click here to learn how to replace the worn governor gear stub shaft and reinstall the same welch/expansion plug. [Return to previous section]

[Return to previous section] | [Top of Page] (Prices are subject to change without notice.) NOTE: A-1 Miller's sell individual engine parts only. Because with "complete" engine rebuild kits that others offer, they always sell you extra parts your engine don't need, and/or leave out parts your engine do need. Completely disassemble your engine to determine which parts your engine needs and if the cylinder in your block and crank journal needs machine work performed, then email me a list of parts. Include the engine's model and specification numbers, too. [Top of Page]
| NOTE: All parts listed below are NEW, unless otherwise stated. A-1 Miller's do not sell cheap junk! As a matter of fact, most OEM Kohler parts are made in China now. Kohler owns some of the factories in China that make the parts. And most aftermarket parts are also made by Kohler in China. Kohler just place the part(s) in a generic box and sell them for less money. So when purchasing a genuine OEM Kohler part that comes in a box with the Kohler name on it, you're really just paying more money for the name. And as far as some parts being no longer available - either the parts didn't sell well or the EPA is trying to phase out parts for the old cast iron block flathead engines because they produce more air pollution than the newer OHV engines. |

so the big end of the rod forms a perfect circle around the crank journal
when installed. Otherwise, if the cap is installed backwards, the "perfect
circle" will be oblong or "egg-shaped," which will bind on the crank journal.
And DO NOT over-tighten the rod bolts or nuts! If the threads strip out in
a rod, then perhaps a longer grade 8 fine thread bolt can be installed in
reverse to serve as a stud (the rod will need to be machined for head bolt
clearance) and use a grade 8 nut. If this cannot be done, then the rod is
scrap metal. |
 Connecting rods. Fits
Kohler engine models K90/K91. NOTE: Crank journal must be reground
.010" undersize to match this rod. The alternative to using an undersize
rod is if a STD size or .010" undersize rod is in good condition, if the
matching-size crank journal isn't deeply scored and/or badly burnt, it can
be reground until it's perfectly round again and then if the original rod
also isn't deeply scored and/or badly burnt, it can be resized to fit to
odd-size undersize journal with the factory recommended .0025" oil clearance.
NOTE - The maximum a connecting rod can be resized to is .005" undersize.
If it's resized more than .005", being the big hole in the rod will be made
excessively oblong or egg-shaped, which will allow it to make less bearing
surface contact around the crank journal after being resized, due to the
centrifugal force at 3,600 RPM, the big end of the rod could become elongated
(metal stretch) and might eventually knock and possibly break. IMPORTANT:
To prevent scoring of the rod when the engine is started for the first time,
apply oil or grease or on crank journal before installing rod. This will
better protect the parts until crankcase oil reaches them.

High Quality Bearing Inserts for Connecting Rods.
Can be used in Kohler engine models K241, M10, K301, M12, K321, M14,
K341, M16, K361, KT19 Series II, M20 and MV20. Available in STD size,
.010", .020", .030" and borable/resizable .060" (limited supply) undersizes.
NOTE: Rod must be bored-out (and notched) to make
room for bearing inserts. And a rod with a burnt aluminum surface can be
bored-out and bearing inserts can be installed.
Click here to learn
how bearing inserts protect an engine. Rods for the before mentioned
engines can be bored and notched to accept bearing
inserts. Even severely burnt, scored, or rods with a mismatched cap can
be bored for installation of bearing inserts. Only USA-made Clevite 77, Federal
Mogul or Sealed Power bearing inserts will be installed. No low quality
Chinese-made bearing inserts ever installed. All A-1 Miller's Professional
Machined connecting rods include ground-out notches to prevent bearing rotation
in rod and drilled oil hole for proper lubrication. Please indicate diameter
of crank journal for size of bearing inserts. (STD size, .010", .020", .030"
or resizable .060" undersizes.) Also, rods can be center-bored for top of
piston to come flush with deck, or bored .020" offset for a .020"± piston
pop-out at no extra charge. [Return
To Previous Paragraph, Web Site or Section]
NOTE: If a crank journal is worn beyond specs or badly scored/burnt,it will need to be reground to the next undersize to match the appropriate size bearing inserts. And if you wish to have A-1 Miller's to bore a rod for you, please let me know if you want the bearing insert centered in the bore of the rod (5.300" rod length; piston flush with top of block), offset .020" (5.320" rod length; safe to use with a milled OEM Kohler stock head and stock head gasket) or offset .060" (5.360" rod length; use with a non-milled OEM Kohler head and stock head gasket) to pop the piston out of the cylinder (see below Ê) to raise the compression and help improve airflow within the combustion chamber for more power and torque. The bearing inserts A-1 Miller's install in Kohler 10-16hp flatheads and 18hp OHV K361 connecting rods can be used for general lawn and garden use, stock or high RPM competition pulling engines. The rod will need to be bored exactly 1.625" for correct bearing to journal oil clearance. NOTE: Being virtually all Kohler K241 and M10 pistons come within .020"± from the top of the block, which lowers the compression ratio. (The factory made them this way for reasons unknown.) A-1 Miller's prefer to bore the K241 10hp rods .020" offset so the piston will come flush with the top of the block. This will allow the engine to produce a little more power. It won't effect the longevity of the engine or cause any problems whatsoever. But sometimes with the .020" offset, the piston will pop out of the cylinder a few thousandths of an inch, which will still hurt nothing. And the bore can be offset .040" for a .020"± piston pop-out. FYI - Before A-1 Miller's machine a rod for installation of bearing inserts, we use a metal "plug" alignment tool that we fabricated to precisely align the big hole of the connecting rod with the centerline of the spindle in my milling machine. Then while the plug is in the rod, we firmly clamp the rod to the milling machine table and after leaving the big hole centered or moving the table so many thousandths of an inch offset for piston pop-out, we lock the table so it won't move in any direction while boring the rod. But for reasons unknown, sometimes the cutting tool will bore the hole in the rod slightly off-center toward one of the bolts or studs. When this happens, we simply grind a small notch on the outside of each bearing shell so they'll clear the rod bolt. I've talked to other machinists who bore Kohler rods also about this and they tell A-1 Miller's sometimes the same thing happens to their rods. But as long as the outside of the bearing shells are notched for clearance of the bolt or stud, the off-center of the bearing inserts poses no problems whatsoever. And bearing inserts for the 10-16hp Kohler engines can be installed in Kohler engine models K482, K532 and K582 STD size connecting rods, but the crank journals would need to be reground exactly to 1.500" to match the inside diameter of the bearing inserts when installed in the rods. And for your information, STD size crank journals for the K482, K532 and K582 engines measures 1.6245". |

 Crankshaft
Main Bearings (Flanged Sleeve Bushings). Fits Kohler opposed twin cylinder
engine models MV16, KT17 (first design), KT17 Series II, KT19 (first design),
KT19 Series II, KT21, M18 MV18, M20 and MV20. NOTE: With these engines,
if one main journal is worn beyond specs (mostly likely the PTO end due to
metal/dirt/debris contamination in the oil because of infrequent oil changes
and/or lack of an oil filter), it can
be reground undersize, and if the other main journal (most likely the flywheel
end) measures within specs (1.742"), it can remain STD size. Remember - metal
flake looks good in paint, not in oil.

 High
Quality 8 Ball Main Crankshaft Radial Bearings. Fits Kohler K-series
and Magnum cast iron block engine models K241, M10, K301, M12, K321, M14,
K341, M16 and K361. Heat treated chrome steel (AISI 52100) for higher resistance
and durability. Supports up to 17,000 RPM. Works excellent for general lawn
and garden engines or for high performance competition pulling engines that
run at high RPM or at
wide
open throttle. FYI - The 8 ball roller bearings have larger diameter
balls than the aftermarket 12 ball roller bearings, that have smaller balls.
Therefore, the balls in the 8 ball bearings rotate slower, causing less friction.
They run freer and more cooler. In
theory, it seems that the 12 ball bearings would work better
in an open throttle pulling engine, but in
reality, it's a different story. Dimensions: 1.57" (40mm)
I.D. x 3.54" O.D. (90mm) x .90" (23mm) width. See note below
Ê. NOTE: If your bearing(s) have more
than .005" of play due to wear, or it feels rough or "rubbles" when rotated
by hand with motor oil applied, then it should be replaced. FYI -
All US and import manufacturers of ball bearings have always been made them
to the metric dimensions. Where applicable, the manufacturers try to make
them close as possible to the inch dimensions.

| Valve Guides -
FYI - Valve guides are made of
either cast iron or bronze, and not steel. Cast iron and bronze are very
hard and porous metals. They absorb oil and lubricate the valve stems for
longer wear. NOTE: The alternative to installing
new replacement OEM-type valve guide(s) is to have the old [worn] guide(s)
reamed for installation of thin-wall bronze sleeves/liners (bushings), which
can be installed by an experienced and reputable automotive machine shop.
Thin-wall bronze valve guides are a low-cost and actually works better than
replacing the OEM guide in most engines. Bronze lasts longer than cast iron
guides because it is harder material and it retains more oil for better
lubrication of the valve stem.

 A-1
Miller's Valve Guide Removal and Installation Tool for use with all Kohler
K-series and Magnum engines. IMPORTANT: The engine block could crack if
guides are removed or installed with a hydraulic press! Therefore, it's
best to use a big, heavy hammer (with this tool) to drive out the old guide
into the valve spring compartment and use the same hammer (with this tool)
to install the new guide externally from inside the valve pocket. When installing
the new guide, be sure to hammer straight down in alignment with the guide
bore hole and not at an angle. Hitting the guide at an angle could cause
it to break. Install new guides until flush with the valve pocket. This tool
can be used with either OEM Kohler and aftermarket offset valve guides. Machined
at a 90º angle where the pilot meets the shank. Dimensions: .300" pilot
x 1/2" diameter shank x 5" overall length. A-1 Miller's part. $20.00
each, plus shipping & handling. [Return

 High
Quality, High Speed Steel Chucking Reamers. Precision ground to provide
correct stem to guide clearance. Will not allow valve stem to be too loose
or too tight in guide. When reaming guide, use an electric hand drill with
plenty of oil in guide. Before installing valve, apply motor oil on stem
for lubrication to reduce wear to guide and prevent valve from sticking.

 Valve
Stem Seals. Required to prevent crankcase oil from draining down into
(OHV) or being suctioned into (flatheads) the combustion chamber through
the guide. Silicone rubber w/metal clamp. NOTE: Apply oil or grease on
valve stem before inserting valve through seal to provide lubrication of
the stem, guide and seal. Dimensions: 5/16" I.D. (stem) x .500" I.D.
(guide) x .600" O.D. NOTE: Some early production KT17 models do not use valve
stem seals.

 Automatic
Compression Release (ACR) Spring. This tiny [hair-like] spring is hard
to find part nowadays. Fits Kohler engine models K141, K161, K181, M8, K241,
M10, K301, M12, K321, M14, K341, M16 and K361. Fits later one-piece camshafts
with the automatic compression release (opens exhaust valve slightly upon
the compression stroke) and not the early two-piece camshafts with the automatic
spark advance. FYI - If you have a Kohler 7-16hp ACR camshaft that was
broke in two by a thrown connecting rod, save the spring off of it. It can
be used on another good cam that may not have one. Or if your ACR spring
places little or weak pressure against the flyweights/levers, it can be re-bent
or reshaped to its original condition to place sufficient tension against
the flyweights/levers.

New-Style, One-Piece, OEM
Kohler Camshafts with Automatic Compression Release (ACR).
NOTE: May or may not come with the tiny (hair-like) automatic compression
release (ACR) spring (see above). If required, reuse the spring off your
camshaft. IMPORTANT: Apply ample amount of clean
motor oil inside cam before installing to prevent seizing of cam on pin!
This will provide vital initial lubrication until crankcase oil reaches the
cam/pin when the engine is first ran. And when reusing
lifters, roughen lifter faces with 600 grit sandpaper to produce a new wear
pattern so the lifters will rotate slightly with every lift to prevent wear
to the cam lobes. Also, the lobes on these used cams have not been reground
for performance. [Top of

Kohler General-Use or Competition Pulling

[Top of Page]
FYI - In order to gain the full benefit of a performance camshaft, just installing this type of cam will not greatly increase the power output of a Kohler engine. Along with the performance cam, the carburetor will need to be bored-out and reworked, the cylinder head will need to be milled .050" to raise the compression ratio, the valves/seats will need to be reworked, and installing an open/unrestricted exhaust header pipe will help, too. All of these things must work together so more air will enter the combustion chamber (and exit the chamber), which will build up more compression to allow the engine to produce more horsepower and torque.
FYI: When the cam lobes are reground, metal is removed from the base circle which reduce the diameter of the base circle in order retain maximum lift at the point on the lobe. The ramps on the lobes are also "rounded" to give the cam more duration. The cam grinding machine's grinding stones are about 1" wide, and after the cam grinding process, we have to manually grind metal away from the sides of the base circles so the edge of the lifters won't "ride up" on the ungrounded areas and hold the valves slightly open when they're supposed to be fully closed. We have to do this to every reground cam we have in stock. Some cam grinders apply a phosphate conversion coating (which resembles flat or matte black paint) to the entire camshaft, especially the lobes. This coating is to prevent galling (wear) during the break-in period and it also covers the secondary grinding areas on each side of the base circles of the lobes so they can't be readily easily seen or noticed. Motor oil with high zinc phosphate content will also protect the cam lobes and other internal moving engine parts from wear during break-in. Otherwise, if everything else is set up correctly with your engine, this cam should work fine. There's no need to be concerned when you receive the cam and see the metal ground away. Also, some of the cams we have, the points lobe is slightly worn. (It's hard to find a good used, 100% unworn cam nowadays.) we include a stainless steel points pushrod with a flared-end to make contact with the unworn areas of the lobe. The pushrod will need to be installed from inside the block before the cam is installed. IMPORTANT: To prevent seizing of camshaft on pin when engine is ran for the first time, apply plenty of motor oil on cam pin and inside cam before installing cam in engine. This will better protect the parts until crankcase oil reaches them.

| FYI: The
OEM valve springs in various models of Kohler cast iron block engines are
not the same. They are not like the OEM springs that's used in a stock small
block Chevy V8's, which are the same. For some reason, Kohler installed a
specific valve spring in a certain model engine to match the cam profile
(lobe lift and duration) so the engine will perform best. And used valve
springs rarely lose adequate pressure. They can be reused as long as they're
not rusted or have been overheated. The rust-pitted areas is a weak spot
and when in operation and under pressure, the spring could
break.

 A-1 Miller's Professional
Repair Service - Resurface air-cooled small engine flathead or OHV cylinder
head on wide, flat
belt- or disc-sander/grinder to remove any warpage and
restore flatness for better sealing of head gasket and prevent possibility
of burning-out of [high dollar] head due to severe warpage. (Sanders are
not just for woodworking.) Includes deburring of sharp edge around combustion
chamber to prevent detonation or pre-ignition.

handling.
NOTE - If it's repairable and reusable, do not discard your cylinder head or other Kohler parts. Most discontinued OEM Kohler parts in good, reusable condition are hard to find nowadays, and nothing works better than the original part(s) the engine is designed for. |
 A-1 Miller's Professional
Repair Service - Mill approximately .050" from Kohler K241, M10, K301,
M12, K321, M14, K341 or M16 cylinder head to raise compression ratio
approximately .75:1 to increase horsepower and torque. Includes remove
prominent/raised gasket mating surface from head and deburr sharp edge around
combustion chamber to prevent detonation or pre-ignition.
Click or tap here for cylinder
head bolt torque specs. $25.00 labor each, plus return shipping

NOTE: To lessen the chance of a blown or leaking head gasket, clean out the head bolt hole threads with a tap, and seal the head gasket with Copper RTV Silicone Sealant (VersaChem - Mega Copper Silicone, Permatex® Ultra Copper® Maximum Temperature RTV Silicone Gasket Maker or Copper SPRAY-A-GASKET Hi Temp Adhesive Sealant) on each side of the head gasket or cylinder head and engine block to prevent a blown or leaking head gasket. Because engine heat has very little effect on silicone rubber. It's made of fine-ground up heat-transferring compressible copper mixed with silicone. Walmart and most auto parts stores sell copper RTV silicone sealant. It doesn't matter which brand to use, they work the same. |
A-1 Miller's Professional Repair Service - Professionally weld up burned-out gasket surface in small engine cylinder head, resurface on a wide, flat belt- or disc-sander/grinder to remove any warpage and restore flatness, and redrill bolt hole, if needed. The welding process involves grinding away the impurities in the aluminum, and the aluminum welding becomes integrated with or part of the aluminum in the head, resulting in superior bonding with no separation whatsoever. NOTE - As long as there's no cracks in the head, it can be successfully welded up, resurfaced, and the bolt hole redrilled. IMPORTANT - The two causes of a burn-out are: 1) Throttle shaft in the carburetor is severely worn, allowing extra air in the combustion chamber, which will lean out the air/fuel mixture at high RPM; 2) The adjustable high speed main air/fuel mixture screw is set too lean; 3) The engine is ran above 3,200 RPM with a [Walbro] carburetor having a fixed/non-adjustable high speed main jet. To prevent the burn-out from happening again, either of these things should be fixed correctly before the cylinder head (engine) is put back into service. $75.00 for welding and machining, plus return shipping & handling. If it's repairable and reusable, do not discard your cylinder head or other Kohler parts. Most discontinued OEM Kohler parts in good, reusable/rebuildable condition are hard to find nowadays, and nothing works better than the original part(s) the engine is designed for.

 High
Quality Cylinder Head Bolts and Flat Washers. Fits Kohler engine models
K141, K160/K161, K181 and M8. Reusable - these will not stretch overtime
and are not
"torque to yield" bolts. OEM Kohler head bolts can be reused
multiple times. But replace bolts with eroded, rusted heads to prevent socket
from slipping so bolt can be torqued correctly to prevent a blown head gasket
and/or warped head. 5/16" diameter x 1-1/2" thread length grade 8 bolts and
hardened washers. NOTES: Clean the bolt holes with a 5/16-18 UNC plug
hand tap, then apply motor oil on the threads so the bolts will torque correctly.
Torque each bolt to 240 in. lbs. or 20 ft. lbs.
Liquid threadlocker is not necessary.

High Quality Aftermarket Single Cylinder Head Stud Kits. These studs can be reused multiple times. These will not stretch overtime and are not "torque to yield" studs. Fits Kohler engine models K241, M10, K301, M12, K321, M14, K341, M16 and K361 with an OEM or Billet Head. Each kit includes 3/8" diameter x 2" or 2-3/4" length high quality heat-treated studs, grade 8 nuts and hardened flat washers. I can also make the head studs any length you want. The ones that's listed here are the most common lengths. When installed correctly and torqued to specs, head studs provide even torque pressure for better head gasket sealing. Plus, with a thinner cylinder wall with a huge, oversized piston, they help maintain cylinder wall stability and straightness for better ring seal to lessen the loss of compression. Thoroughly tested for several years of continuous use under pulling conditions, for Kohler engine models, hardened and heat-treated coarse thread studs, along with grade 8 nuts and washers, works just fine, with no problems. The nuts maintain their torque as long as they're tightened to the correct torque specs. And make sure at least 3/4" of threads are in the block so the cylinder wall will not distort and threads in block will not strip out when the nuts are torqued to specs. Click or tap here for cylinder head bolt torque specs. Also, stud length is determined by type of cylinder head. The OEM head with short bolt holes require 2" length studs, the head with tall bolt holes require 2-3/4" length studs. Please indicate length of studs when placing order. IMPORTANT: As with any threaded stud, apply medium strength liquid threadlocker (Blue Loctite, Permatex or equivalent) on threads that goes in the block and tighten with pliers to prevent stud from loosening. Use a hardened steel flat washer under nut to distribute load evenly on head and apply motor oil on exposed threads so nut will torque correctly. Torque each nut to 360 in. lbs. or 30 ft. lbs. in correct sequence. FYI - When storing an opened container of liquid threadlocker or Super Glue, store it upright and not laying flat. The [capped] tip will not dry out and clog when stored upright. [Return To Previous Paragraph, Section or Website]

Replace damaged or broken off threaded stud on flywheel end
of crankshaft with installation of...
Center drill and cut threads in PTO end of crankshaft for installation of 3/8" UNF grade 8 bolt. $75.00 each, plus return shipping & handling.
Crankshaft Regrinding - This service includes all makes and models of small engine crankshafts.
"Round Up" Crankshaft Rod Journal(s) and Resize Connecting Rod(s) - This service is for most makes and models of small engines when an undersize connecting rod or bearing inserts isn't available, if the crankshaft is worn beyond .010" and needs to be reground again, the journal can be reground to wherever it "cleans up" or is true again, then the connecting rod can be resized so it'll fit the smaller undersize journal with the factory recommended .0025" oil clearance. To resize the rod so it'll fit to a few thousands of an inch smaller diameter crank journal, first, metal is removed from the mating end of the rod cap, then the cap is fasten to the rod. The big hole in the rod is now oblong or "egg shaped." Then the big hole in the rod is honed until it's .002" larger than the diameter of the crank journal. Honing reshapes the hole into a perfect circle again, only smaller in diameter. This works very well and it lasts as long as an ordinary STD size rod and crank journal. This can only be performed on a rod with a good bearing surface. It cannot be done on a burnt or heavily scored connecting rod because too much metal would need to be removed. If you're interested, we will need your crankshaft and connecting rod(s). NOTE - The maximum a connecting rod can be resized to is .005" undersize. If it's resized more than .005", being the big hole in the rod will be made excessively oblong or egg-shape, which will allow it to make less bearing surface contact around the crank journal after being resized, due to the centrifugal force at 3,600 RPM, the big end of the rod could become elongated (metal stretch) and might eventually knock and possibly break. NOTE: Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds. YouTube video: Single cylinder crankshaft regrind.
Precision Dynamic Spin-Balance Service - If your engine vibrates excessively or more than normal, and if the parasitic accessories or attachments are not out-of-balance, then chances are, the rotating assembly (crankshaft, connecting rod and piston assembly, and/or flywheel) needs to be precision balanced.

Oil Level Check and Drain Plugs, Oil Filter Adapter, Oil Filters and OEM Kohler Cast Aluminum and Cast Iron Oil Pans - Please contact A-1 Miller's if you're interested in purchasing any of the products or services listed in this website. If you need a part or parts that's not listed in this website, please contact A-1 Miller's and we'll see if we can get it at a reasonable price. .

| Oil Level Check and Drain Plugs with Tapered Threads and Square Head
listed below. A-1 Miller's oil drain plugs have a super strong rare
earth/neodymium magnet. Five times stronger than competitor's ceramic (ferrite)
magnet and resists demagnetization. Plugs listed below can be used on various
other makes and models of transmissions, transaxles, gearboxes and small
engine crankcases. Tapered threads requires no sealing gasket or sealant,
and threads will not strip out when tightened. To avoid cracking oil pan,
do not over-tighten! When in doubt, use
plumber's thread sealing tape to insure proper sealing
of threads to prevent a possible oil leak. Universal application. Magnet
attracts and removes
ferrous
metallic wear fragments from the motor oil or transmission/gearbox to reduce
engine or gear/bearing wear. Sometimes some of the ferrous wear fragments
settle to the bottom of the oil pan and do not drain out with the oil when
performing an oil change, even when the oil is hot. Magnetic drain plugs
are suitable for engines with splash oil lubrication (no oil pump/filter).
The engine, transmission, transaxle or gearbox will last much longer with
uncontaminated and cleaner oil. Remember - metal flake looks good in paint,
not in oil.
FYI - If you don't know or can't find any information on the maximum oil quantity for any specific gear drive transmission, transaxle, right angle gearbox, or garden tiller sealed chaincase or gearbox, well, the unit in question is full when oil runs out of the oil level check/fill plug hole that's located halfway [of the drive axles or lower output shaft(s)] on the side(s), front or rear of the unit. All of these fill this way. When the unit is in motion, the lower gears in a transmission or transaxle picks up the oil and slings it on the upper gears, shafts and bearings to lubricate them. And in automotive rear ends, the ring gear picks up the oil and slings it on the pinion gear, spider gears, shafts and bearings to lubricate them. Due to high friction between the gear teeth in transmissions, transaxles, right angle gearboxes and garden tiller gearboxes, or an "open" (non-locking, free-spinning) rear end or in an automotive rear end with a Detroit Locker, SAE 90 weight gear oil must be used. But in an automotive Posi-Trac limited-slip differential, SAE 90W140 weight gear oil must be used to prevent chattering of the locking clutches going around turns. And due to much less friction of roller chain(s) on sprocket teeth in a sealed chaincase, 10W30, 10W40 or SAE 30 weight heavy duty motor oil can be safely used. In front-wheel-drive vehicles, the differential is typically built into the transmission or transaxle, and shares the same transmission fluid, rather it be SAE 90 weight gear oil for a manual shift transmission or ATF for an automatic transmission.  1/8" NPT Oil Level and Drain
Plugs. (0.405" O.D. tapered threads.) All MTD-built Cub Cadet garden tractor
aluminum housing creeper drive units are packed with grease from the factory.
Therefore, for better lubrication and less wear inside the creeper drive
unit, install ordinary plug on opposite side of unit of shifter to serve
as an oil level check, and install magnetic plug on bottom of unit to attractive
metallic wear fragments and drain/change the oil. Entire creeper unit must
be completely disassembled and cleaned, a hole drilled midway on the side,
another hole drilled on the bottom, and both holes will need to be threaded
with an 1/8" NPT hand tap for the plugs. Then fill unit through the breather
opening with SAE 90 weight gear oil. $8.00 for both plugs, plus shipping
& handling.
 1/4" NPT Magnetic Oil Drain Plug.
(0.540" O.D. tapered threads.) Fits various Briggs & Stratton, Kohler,
Tecumseh, and various other makes and models of small engines. A-1 Miller's

shipping & handling.
 3/8" NPT Magnetic Oil Drain
Plugs. (0.675" O.D. tapered threads.) Fits various Briggs & Stratton,
Kohler, Tecumseh, and various other makes and models of small engines.
1/2" NPT Magnetic Oil Drain Plug. (0.840" O.D. tapered threads.) Fits side of oil pan on Kohler engine models K141, K160/K161, KV161, L160/L161, L181, K181 and M8 engines, and oil drain on Cub Cadet garden tractor transaxles, various automotive manual shift transmissions, and various other makes and models of small engines. A-1 Miller's part. Not available from Kohler. $5.00 each, plus shipping & handling. 3/4" NPT Magnetic Oil Drain Plug. (1.050" O.D. tapered threads.) Fits various Briggs & Stratton, Kohler, Tecumseh, and various other makes and models of small engines. A-1 Miller's part. Not available from Kohler. $5.00 each, plus shipping & handling.  5/8" I.D. Fiber Sealing Gasket.

 3/4-10 UNC (Straight Threads)
Magnetic Oil Drain Plug. Use to replace OEM Kohler 3/8" NPT oil drain plug
with stripped threads in [aluminum] oil pan. Includes fiber sealing gasket.
NOTE: Threads in oil pan must be enlarged with a 3/4-10 UNC hand tap.
A-1 Miller's part. $5.00 each, plus shipping & handling. |
 Super
Strong Rare Earth/Neodymium Magnets for Engines, Transmissions, Transaxles
and Gearboxes. Attracts and removes ferrous metallic wear fragments from
the lubricating oil inside an engine that does not have an oil pump with
an oil filter, or inside a transmission, transaxle or gearbox to lessen wear
and noise to gears and bearings. Sometimes some of the wear fragments settle
to the bottom of the oil pan, engine block or gearbox and do not drain out
with the oil when performing an oil change, even when the oil is hot. Install
magnet in bottom of oil pan away from the oil dipper and any moving parts,
or in bottom of a transmission, transaxle or gearbox away from rotating gears
and any moving parts. Use
Krazy Glue,
Super Glue,
Gorilla Glue, or any industrial strength adhesive to secure
magnet in place. The engine, transmission, transaxle or gearbox will last
much longer with uncontaminated and cleaner oil. These rare earth/neodymium
magnets are EXTREMELY strong! Use caution when handling! Can be difficult
to remove from a steel or cast iron surface, are very brittle and can break
easily if mishandled. Remember - metal flake looks good in paint, not
in oil.

 Bolt-On Header Pipe Kits. Fits
Kohler Engine Models K241, M10, K301, M12, K321 and M14. For competition
pulling engines with stock-size or oversize valves running at 4,000 RPM or
at open RPM. High grade durable and galvanized-coated mild steel pipe resists
rust and will not rust or discolor, even from exhaust heat. Has a 90º,
4" radius bend; each pipe extends 8" from exhaust port to midway of bend
for plenty of hood clearance and measures 18" upward from midway of bend.
Kit includes 1-5/16" O.D. x 1.260" I.D. x 24" overall length header pipe,
2-1/2" O.D. x 1-5/16" I.D. x 5/16"± thickness round mounting flange
and two 5/16-18 UNC Allen head bolts. Flange fastens directly to engine block
without a round mounting adapter and clamp, just like automotive engines
with headers. No gasket required; use
clear RTV silicone adhesive sealant instead. By the
way - Silicone is heat-resistant, it will NOT burn out, even with extreme
exhaust heat.
 FYI: When I have my 1-5/16" pipes
bent at a local automotive muffler shop, being there is no 1-5/16" I.D. die
to fit around the pipe, I use a 1-1/4" I. D. x 1-1/2" O.D. x 12" length steel
tube, split in two, with one half cut in two, then I place them inside the
1-1/2" die. And sometimes while the pipe bends, this creates slight crinkles
on the sides of the elbow, which will not interfere with the exhaust flow
whatsoever. Click photos to the right for a larger view.

For Kohler engine models K241,
M10, K301, M12, K321, M14, K341, M16 and K361. This particular cam profile
design is suitable for heavy lawn and garden work, snow removal, etc., or
stock competition pulling to provide more torque (lugging power) and improved
engine performance from 3,800 to 4,200 RPM. The lobes on this cam are not
welded up. They are professionally and precision reground on a cam grinding
machine to have the factory stock lift, but with slightly increased duration,
which makes it perform best around 4,000 RPM. This cam will pass tech for
a stock cam. It will add about 3 more horsepower and 2 ft. lbs. of torque
to the average stock engine with more lugging power than the OEM Kohler K361
cam.
This cast cam performs best with our performance
BLUE valve springs (listed below; to
prevent fuel spray out the carburetor and lifter chatter), race-quality retainers
(or the OEM Kohler stamped steel retainers can be used), quality valve job,
ports made larger, and a reworked carburetor with a bored-out venturi for
maximum performance for competition pulling. If there's any restriction of
airflow in and out of the combustion chamber, the cam will not perform at
100% efficiency. This cam builds up the compression about 6% more than the
K361 cam, and approximately 11% more than the flathead engine cams at around
4,000 RPM. This cam sounds just like an OEM Kohler stock cam. You can't hear
the difference out the exhaust. The duration and centerline of the lobes
on this cam helps the engine produce the most power and torque between
3,600-4,500 RPM. At higher RPM, due to the limited duration, no substantial
gain in power or torque will result. If the engine is built to the max, tractor
is geared correctly and traction is adequate, engine shouldn't bog down much
with this cam. It'll keep pumping out the ponies right out the gate! Use
with the OEM Kohler 1" base lifters. When reusing lifters, roughen lifter
faces with 600 grit sandpaper in an erratic pattern to produce a new wear
pattern and so the lifters will rotate slightly with every lift to prevent
wear to the cam lobes. Use the
