NOTE: All parts listed here are NEW, unless otherwise stated. I do not sell cheap junk! As a matter of fact, many of the OEM Kohler K-series and Magnum engine parts are still made in the U.S. The Kohler Courage engines and parts are made in China. As a matter fact, Kohler owns two factories in China that make the parts. And most aftermarket parts listed in this website are also made by Kohler to Kohler's strict specifications. 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 on the box. 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.

NOTE: High-quality ring sets, pistons and piston/rings assemblies are also available for other makes and models of small gas engines. And the piston assemblies that we sell will work with a stock connecting rod and crankshaft without the need for rebalancing. And always match a billet connecting rod of a certain length to an aftermarket piston (Arias, JE, etc.) that has the correct compression height. These two parts must be matched for the piston to come flush with the top of the engine block, or have a few thousands of an inch pop-out. If using a Kohler connecting rod, the compression height may not be correct with an aftermarket piston (Arias, JE, etc.) that has the wrong wrist pin offset. The same is true with a Kohler piston and a billet connecting rod of a the wrong length. You can find piston ring compressors on eBay.

NOTE: Complete engine rebuild kits are available, but a kit will cost more than if the parts were ordered individually. So please contact me with a list of parts you need, and I'll get back to you with a total including shipping & handling. And if you need a part or parts that's not listed here or for other make and model of engines, please contact me and I'll see if I can get it at a reasonable price. Please contact me if you're interested in any of the above parts or items.

New and Used OEM Replacement Connecting Rods -

Upon installation of a connecting rod in a Kohler engine, the oil hole in the cap faces toward the camshaft! There's "match marks" on both the rod and rod cap. They MUST be aligned or "matched up" 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.

Bore and notch Kohler 10hp-18hp cast iron block single cylinder and KT21, M20 and MV20 twin cylinder connecting rods for installation of bearing inserts. $25.00 labor each, plus shipping & handling. NOTE: If a crank journal is worn beyond specs or badly scored/burnt,it will need to be reground to match the appropriate size bearing inserts. And if you want me to bore a rod for you, please let me know if you want the bearing insert centered in the bore of the rod (piston flush with top of block) or offset .020" or more (up to .125" at no extra charge) to pop the piston out of the cylinder (see below) to raise the compression and help improve air flow within the combustion chamber for more power and torque. The bearing inserts I install in Kohler 10-16hp flatheads and 18hp OHV K361 connecting rods can be used for general yard work, stock or high rpm pulling competition engines. And the rod needs to be bored exactly 1.625" for proper bearing to journal clearance. NOTE: On the K241/M10 (10hp) Kohler engines, the piston seems to come within .020"± from the top of the block, which lowers the compression ratio. Therefore, when boring the rod for installation of bearing inserts, it'll be a good idea to offset the bore .020" towards the oil dipper (lengthen the rod by .020") so the piston will be more or less flush with the top of the block. And offset the bore .040" for a .020"± piston pop-out. And bearing inserts for the 10-16hp Kohler engines can be installed in Kohler 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". . Narrow wrist pin width on 12hp or 14hp (old style) connecting rod for use with K-series 16hp cast piston or "new style" forged Mahle pistons. $20.00 labor, plus return shipping & handling.

Reground Low RPM Performance Torque Cam Reground 4,000± rpm performance torque cast cam for Kohler K-series and Magnum engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp) and K361 (18hp OHV). This cam profile has stock lift with increased duration and will pass tech for an OEM Kohler stock cam. It adds about 3 more horsepower and 2 ft. lbs. of torque to an average stock engine with more lugging power than the 18hp cam. This cam performs best with reworked and undercut valves for more airflow, ports made larger and the venturi in the carburetor bored out. If there's any restriction in and out of the combustion chamber, the cam will not be able to perform at 100% efficiency. This cam profile helps the engine produce the most power and torque between 3,600-4,500 rpms. At higher rpms, no substantial increase in power will result. This cam sounds just like an OEM stock cam. You can't hear the difference out the exhaust. It's perfect for a competing stock pulling tractor or for heavy yard work. Use with stock lifters. To prevent breakage, use only OEM or light-weight Stock-Altered single valve springs with this cam. This cam installs just like the OEM cam. Just thoroughly lubricate the inside with motor oil, align the timing marks on the gear teeth, set the end-play and valve clearances to OEM specs, and it should be good to go! 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, I 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 unground areas and hold the valves slightly open when they're supposed to be fully closed. I have to do this to every reground cam I have in stock. 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 I have, the points lobe is slightly worn. (It's hard to find a good used, 100% unworn cam nowadays.) I 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. Outright: $150.00 each, plus shipping & handling. With core trade-in: $125.00 each, plus shipping & handling. Only the one-piece cam (originally with the automatic compression release) will be accepted as a core. Core must be in good condition, no cracks, never reground or welded on before with gear teeth in good condition, minimal wear on points lobe and preferably the compression release tang intact. When sending a core to me, please include a note with your name, mailing address, phone number and that you want to trade the cam in as a core for the Reground Torque cam. I will then deduct $25.00 from the price of the cam. Please send your core to: A-1 Miller's Performance Enterprises, 1501 W. Old Plank Rd., Columbia, MO 65203-9136 USA.
Coming Soon! Hot-Stock and Stock-Altered Camshaft for Kohler K-series and Magnum engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp) and K361 (18hp OHV) Pulling Engines. Lobes are hard surface welded on an OEM cast cam, then precision ground to give it a stock lift (.325"-.330"), but much more duration. This cam profile performs best with reworked and undercut stock size valves or bigger valves for more airflow, ports made larger and the venturi in the carburetor bored out. If there's any restriction in and out of the combustion chamber, the cam will not be able to perform at 100% efficiency. This cam profile helps the engine produce the most power and torque at high rpms or at wide open throttle operation. If used in a 4,000± rpm engine, no substantial increase in power will result. Single, Stock-Altered springs required for this cam. Stock OEM Kohler 1" base lifters can be used. Outright: $200.00 each, plus shipping & handling. With core trade-in: $175.00 each, plus shipping & handling. Only the one-piece cam (originally with automatic compression release) will be accepted as a core. Older steel cams will be accepted, too. Core must be in good condition, no cracks, never reground or welded on before with gear teeth in good condition, minimal wear on points lobe and preferably the compression release tang intact. If core has a worn lobe, but the rest of the cam is in good condition, that would be fine because it will need to be welded up (and then reground) anyway. When sending a core to me, please include a note with your name, mailing address, phone number and that you want to trade the cam in as a core for the Reground Torque cam. I will then deduct $25.00 from the price of the cam. Please send your core to: A-1 Miller's Performance Enterprises, 1501 W. Old Plank Rd., Columbia, MO 65203-9136 USA.

Reconditioned OEM Crankshafts, Balance Gears and New Main Bearings -

Reconditioned OEM Kohler Crankshafts - [When available.] 10hp, 12hp, 14hp and 16hp K-series and Magnum flathead single cylinder engine crankshafts. These cast iron cranks are genuine Kohler parts, used and in excellent condition. They may have either a 1" or 1-1/8" diameter x 3-1/2" long keyed PTO shaft and may have a STD size or freshly reground .010", .020" or .030" undersized journal. Although .030" is rare, it's still safe to use. And if you're going to use a pulley, clutch, etc., on the PTO end, then I need to know the exact dimensions of the PTO end on your crankshaft so I can match it to one that I may have in stock. Measure the diameter and length from the gear teeth out. If you know your engine's exact model and specification numbers, you can go to kohlerplus.com, find the part number for the crankshaft, and then find the dimensions and specifications of the crankshaft here: CRANKSHAFT REFERENCE MANUAL.

Our part #150-973 OEM Kohler part. $116.55 each, plus shipping & handling. NOTE: With the main bearings removed from an engine, and if all the oil is cleaned from the bearings, allowed to thoroughly dry, and then the bearings are spun by hand, and if the bearings isn't worn much or at all, they might feel "rough" and make a rattling sound. This rattling sound isn't necessarily because the bearing is worn. The noise is caused by the balls running dry on the races because there's no oil to separate them. They're simply making metal to metal contact. Try applying a small amount of motor oil to the balls/races and then spin them. They should now be a lot quieter. The same thing will happen with new ball bearings. By the way - Most main bearings in a Kohler engine will wear extremely little, if any at all, and usually don't require replacing. Although some main bearings will wear (which is obvious), and need to be replaced. And excessively worn main bearings will make a rumbling noise and the engine will have a more than-usual-vibration.

Crankshaft Repairs - Remove burnt aluminum and polish journal to shiny finish. $10.00 each journal. I chuck the crankshaft in my big metal lathe, turn it on slow and use my crankshaft polisher with a sanding belt to remove the burnt aluminum. This works great until the aluminum is gone, but sometimes the journal is scored or worn. Then it requires regrinding to the next undersize. If it's not scored or worn, then it can be reused as is. But if it is worn, an undersize rod and possibly one with a bearing insert is required. If it does need regrinding, then there's no charge for cleaning it. Regrind journal (crank pin) to next undersize. $60.00 per journal. Note: Kohler crankshafts can be reground to .030" undersize and still be safe to use with matching undersized bearing inserts installed in the connecting rod. And all crankshafts, rather if they're automotive or small engine, are checked for straightness before grinding. If they're bent or twisted, sometimes they can be straightened. We also do offset crankshaft grinding to increase the length of the stroke at no extra charge. Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds. For most makes and models of 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, and then the connecting rod can be resized so it'll fit the smaller undersize journal. 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. The cost for having this done is $100.00 labor for a single cylinder engine, and $200.00 for a two cylinder engine, plus return shipping & handling. If you're interested, we will need your crankshaft and connecting rod(s). Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds. Repair broken off 5/8" stud on flywheel end of crankshaft. Center drill and cut threads for a 3/8" diameter grade 8 bolt in the end of crankshaft. $25.00 labor, plus return shipping & handling. Drill hole and cut 7/16-20 NF threads in the PTO end of the crankshaft for bolt and flat washer. $25.00.

Bore and notch Kohler 10hp-18hp cast iron block single cylinder and KT21, M20 and MV20 twin cylinder connecting rods for installation of bearing inserts. $25.00 labor each, plus shipping & handling. NOTE: If a crank journal is worn beyond specs or badly scored/burnt,it will need to be reground to match the appropriate size bearing inserts. And if you want me to bore a rod for you, please let me know if you want the bearing insert centered in the bore of the rod (piston flush with top of block) or offset .020" or more (up to .125" at no extra charge) to pop the piston out of the cylinder (see below) to raise the compression and help improve air flow within the combustion chamber for more power and torque. The bearing inserts I install in Kohler 10-16hp flatheads and 18hp OHV K361 connecting rods can be used for general yard work, stock or high rpm pulling competition engines. And the rod needs to be bored exactly 1.625" for proper bearing to journal clearance. NOTE: On the K241/M10 (10hp) Kohler engines, the piston seems to come within .020"± from the top of the block, which lowers the compression ratio. Therefore, when boring the rod for installation of bearing inserts, it'll be a good idea to offset the bore .020" towards the oil dipper (lengthen the rod by .020") so the piston will be more or less flush with the top of the block. And offset the bore .040" for a .020"± piston pop-out.. And bearing inserts for the 10-16hp Kohler engines can be installed in Kohler 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". Narrow wrist pin width on 12hp or 14hp (old style) connecting rod for use with K-series 16hp cast piston or "new style" forged Mahle pistons. $20.00 labor, plus return shipping & handling.

Please contact me if you're interested in any of the above parts or services.

K241 (10hp) bare block. $65.00 each, plus shipping & handling. K241 (10hp) bare block with 10hp bore and K301 embossed on the PTO end. (Extra thick cylinder wall.). $200.00 each, plus shipping & handling. K301 (12hp) bare block. $125.00 each, plus shipping & handling. K321 (14hp) bare block. $150.00 each, plus shipping & handling. K341 (16hp - 12 fin) bare block. $250.00 each, plus shipping & handling. K341 (16hp - 13 fin) bare block. $400.00 each, plus shipping & handling. Packaged shipping weight for each block is 25 lbs. NOTE: There are many variations in the K241 (10hp), K301 (12hp), K321 (14hp) and K341 (16hp) Kohler blocks: Some blocks have a wide base (flanges) and some have a narrow base. The very early 10hp blocks have no indention for installing an upper mount gear starter. Also, some of these blocks with flanges (for the wide oil pan) have no holes drilled for converting to a narrow base oil pan. (But the holes can be drilled and tapped.). Some have the oil dipstick tube hole next to the cylinder, while others have no hole there. The hole is either drilled or threaded. Some blocks have provisions for a starter-side mounted oil dipstick tube, and some don't. Some blocks come with balance gears and some don't. Some have a plug where balance gear stub shafts can be installed, and some have no holes drilled for the stub shafts. Some blocks have two threaded holes for mounting an exhaust pipe flange and provisions to mount a mechanical fuel pump, and some don't have these. The threaded holes on the PTO end of the block can have different bolt patterns. A 12 fin 16hp block works great for the Stock, Stock Altered and Missouri Super Stock classes, and the 13 fin 16hp block works better for the 50+ cube class because it has a thicker cylinder wall. Other than the above, everything else on the blocks are pretty much the same.

Engine Rebuilding Service - I rebuild engines from ordinary stock up to 4,000 rpm governored pulling engines. I can rebuild your engine however you want. Just tell me know how you're going to use your tractor or equipment and I'll build your engine to suit your needs. If you wish to have me rebuild or build-up your engine, I'll need a list of what you want done to your engine or a copy of your club's pulling rules regarding the engine requirements before I can give you an estimate on the cost. I'll build your engine to the limit according to the rules, not less than what the rules allow. I also rebuild ordinary lawn and garden equipment engines too, such as cast iron and aluminum block single- and twin-cylinder flathead, OHV and v-twin Briggs and Stratton, Kohler, Tecumseh and 2-cycle LawnBoy. I've never encountered an engine I couldn't repair! Whenever I rebuild or build-up an engine, and if you wish to do so, I do whatever it takes so it'll produce the factory-rated horsepower or the maximum horsepower and torque, and last a long time. I go beyond what the repair manual says to do. I can get all the parts needed, too. I can build your engine so it'll be legal for the class you plan to pull in. And with my engine rebuilds and build-ups, you may not always win, but you'll look good trying! All pulling engine builds are strictly confidential. This means your pulling competition will not know what goes into your engine! For proper break-in of a new or freshly rebuilt engine, use ordinary SAE 30 weight motor oil so the internal parts will get hot and produce a wear pattern. Run an engine with aluminum cylinder wall(s) normally for 2 hours, or for an engine with cast iron cylinder wall(s), run it normally for 5 hours. Then drain the oil while it's hot, and either continue to use ordinary SAE 30 oil, or switch to a quality 20W50 synthetic blend or full synthetic oil for warm weather use. Or use ordinary 10W40 oil, or 10W40 synthetic blend or full synthetic oil during cold winter use. Use no oil additives. Full synthetic oil don't get as hot as ordinary oil does. It's more slippery and remains cooler than ordinary oil even after the engine has been in operation for several hours to better protect internal parts for longer engine life.

Below are details and prices to rebuild your engine - FYI - Being I'm the only person to read and respond to all my customer's emails (about 20 or so per day), take my customer's phone call orders (about 20-30 on a nice day with good weather), with customers stopping by my shop, repair and rebuild my customer's parts and engines in my shop, order parts from my suppliers, process orders, package parts and then mail customer's parts at my local Post Office, etc., it may take me several months, possibly up to 6 months to rebuild an engine. I also have to depend on other local machine shops to balance engine parts, perform various machine work that I can't do myself. All this takes time. So please keep this in mind if you decide to have me rebuild/build your engine. Also, I don't like to rush on my customer's repair jobs. I'm very particular about my work, especially my engine builds. I like to take my time to make sure that everything is right, the engine will run right, produce full power and last a long time. I appreciate for you understanding my situation. - Brian Miller

Competitive Pulling Engine Refreshing Service Ê A typical pulling engine will last an average of 25 pulls or 3 years of use. After that, it may start to lose power when under load and puff smoke out the crankcase breather vent and/or out the exhaust. When this happens, it's time for a refreshing job. This service is for engines that have been previously rebuild or built for pulling, and needs the basic parts to revive the power. It is not a complete rebuild. Refresh Stock 10-16hp Kohler pulling engine. Includes new rings, lap valves, adjust valve clearance, new rod bearing, clean or rebuild carburetor, new up-to-date Lakota, MWSC or Vogel torque camshaft and new gaskets. $200.00 labor, plus return shipping & handling.

Produces ± 38hp and 33 ft. lbs. of torque @ 6,500 rpm (Wide Open Throttle - no governor). $2,500.00±* *Crating and shipping charges not included in prices above. ± means more or less, depending on your club's rules and restrictions. FYI - I build engines as customers order them according to their tractor's make and model. I will also need your pulling club's engine rules and requirements so the engine will be legal within its class. And I don't offer any chrome-plated sheet metal because the chrome plating process is cost-prohibited.

NOTES:

• A general stock engine rebuild includes: completely disassemble entire engine, clean and inspect all parts, bore (if it needs it) or deglaze cylinder, install new piston/rings/pin/clips assembly, regrind crankshaft journal (if it needs it), install new undersize (.010") connecting rod or bore rod for undersize bearing inserts (.020" or .030"; if it needs it), grind valves and seats, install new gaskets with silicone sealer to lesson oil leaks, install new ignition tune up components, resurface cylinder head, clean and rebuild carburetor, clean commutator and lubricate bushings in gear starter and whatever else the engine may need so it'll run well and last a long time.
• The engines I sell are turn key engines. I build all engines according to the customer's personal preferences for non-pulling purposes or to the customer's pulling club's sanctioning rules. "Build to the max" means engine will produce all the power possible and still remain stock-appearing externally. All of the above will be performed in addition to the mild performance modifications.
• ± means more or less. This means if your engine needs minimal labor and/or machining, the price will be slightly less. But if it needs more than usual labor and/or machining, the price will be slightly higher. However, if it has sustained major internal damage or if it needs additional parts, extensive machine work and more labor, then the price will be even higher. And being I can't see your engine before you bring or send it to me, I can't honestly give an exact quote beforehand. But I'll treat you right and I'll try to keep the costs down as much as possible and still build you a quality engine so it'll start easy, produce full power and last a long time. The ± also depends on your personal preferences, parts needed and/or your pulling club's sanctioning rules. Also, if you wish to furnish some or all of the parts yourself, the price will be substantially lower.
• When sending or bringing an engine to me, I don't need everything on it. Only the things that can wear and need rebuilding or refurbishing, such as the gear starter, cylinder head, crankcase breather assembly, fuel pump, carburetor and flywheel. I need the oil pan on it too, to prevent dirt and dust from entering the crankcase. A 50% deposit may be required on some engine rebuilds. Regular shop hours are 9:00 am - 5:00 pm, Monday-Friday, except Holidays. If you are traveling a great distance, it's best to call in advance (573-875-4033) to make sure that I will be here when you plan to stop by.
• All rebuilt engines returned (shipped) to the customer come with a 90 day workmanship warranty from date of pickup or delivery. And for proper break-in of a freshly rebuilt engine with an aluminum cylinder wall, run it normally for 2 hours, or for engines with a cast iron cylinder wall, run it normally for 5 hours. Use ordinary SAE 30 weight motor oil so the internal parts will get hot and produce a wear pattern. Then drain the oil while it's hot, and either continue to use ordinary SAE 30 oil, or switch to 20W50 synthetic blend or full synthetic oil for warm weather use. Or use ordinary 10W40 oil, or 10W40 synthetic blend or full synthetic oil during cold winter use. Full synthetic oil don't get hot like ordinary oil does. It remains cool even after the engine has been in operation for several hours to better protect internal parts for longer engine life.

If you decide to ship your engine to us, please enclose it in a sturdy wooden crate with cushioning surrounding the engine, and then fasten or strap it securely onto a wooden pallet. Do not use a cardboard box alone! To build a crate, start with 2" x 2" frame work with a skid pallet on the bottom (so a forklift can pick it up without damage), fasten the oil pan of the engine to the bottom of the crate (pallet), use either 1/4" plywood or paneling to cover the crate, place some heavy pieces of Styrofoam or folded cardboard around and above the engine to help cushion it during transport, and fasten everything on and in the crate with sheet rock screws. Or if you bring an engine to me in person, sit it in an automotive tire to keep it from moving around during transportation. And please let me know first so we can expect your arrival. It'll be best to have everything on the engine that can wear so we can repair them too, and make the necessary adjustments.

To ship your engine to us, first off, do not use the US Mail Service, UPS or FedEx Express! We and our customers have had too many problems with them in the past. They wouldn't even make good on the insurance either. Their gorillas (employees) are trained in handling lightweight packages (weighing up to 70 lb.) and the heavier items tend to get damaged with their kind of handling. They are very hard on heavy packages when they handle them. The packages are placed on conveyor-belt systems and they seem to always drop the heavy ones off of the elevated conveyors, which usually destroys whatever is inside them.

If you decide to ship your engine to me, please crate it well. We're authorized FedEx Ground (for anything up to 150 lbs.) and FedEx Freight (for anything over 150 lbs.) shippers because they've been proven to be the lowest cost, most gentle and reliable shipping companies. Here's a great web site that calculates freight charges. Go here: http://www.shipgooder.com/ and type in your zip code, our zip code (65203-9136) and the crated weight of a typical complete 10-16hp Kohler engine (145 lb.). Shipgooder doesn't ship anything. It's web site just lets you see the latest cost of various shipping companies. Contact your local FedEx Ground for more details and to schedule a pickup. Or you can use a major trucking company with a good reputation for shipping heavy, fragile objects. Look in the Yellow Pages and ask around. The reason we say this is because we once returned a rebuilt engine that was crated very well to a customer using a well-known shipping company, and it was almost destroyed in shipping when he received it. You'll have better success with shippers such as FedEx Ground, FedEx Freight, Roadway, etc. Freight company employees are trained in handling heavy packages plus they use tow motors to move the freight around, not like UPS or FedEx Express with their uncaring "gorillas" unloading and loading the trucks. The approximate shipping weight of a crated 7 and 8hp Kohler engine is 100 lbs. And 10-16hp single cylinder cast iron Kohler engine is 145 lbs.

To ship an engine, freight companies require it to be in an enclosed wooden or sturdy plastic crate. It's best to securely fasten it with the oil pan bolts on a pallet made of 2 x 4's and fasten the boards together with long drywall screws, not nails. Then place a 2 x 2 wooden frame around the pallet and fasten 1/4" plywood with a 2 x 2 frame work. Run cross-braces which encompasses the top portion of the cylinder of the block. This will support or stabilize the top of the block and keep the engine from getting ripped off the base. Put a lid on the top and then load it in the trucking company's truck when it arrives with a tow motor. You shouldn't have any problems shipping an engine this way.

To ship a transaxle, this is easier. They don't require an enclosed crate. Just place the transaxle on the center of a wooden pallet and stretch wrap (use low-cost ratchet nylon tie-downs) to securely fasten it to the pallet. Use at least 6 layers of stretch wrap or several tie-downs. This should work really well. The shipping weight of a Cub Cadet cast iron case transaxle when strapped to a wooden pallet is approximately 215 lbs.

When bringing or sending your engine, transaxle or any other part(s) to us, please include a note with your name, address, phone number and a description of what you want done.

The Reason For Superseded Part Numbers -

When President Nixon was in office, he placed a price freeze on all products being manufactured in the US at the time. The manufacturers couldn't raise their prices even if it cost them more to produce their parts. What happened was the government placed the freeze on the part number of each part. So manufacturers simply gave their parts a different part number so they could legally raise the prices.
