Normal High Speed or Wide Open Throttle Engine Vibration in Competition Pulling Can Cause an Oil Pan to Loosen and Possibly Break!

To prevent the oil pan from becoming loose under a competition pulling situation, if necessary, first have the flywheel and crankshaft and piston/connecting rod assembly dynamically and precision spin-balanced, and DO NOT USE AN OIL PAN GASKET! Instead of a gasket, apply a thin bead of clear RTV silicone adhesive sealant between the block and pan, then torque the bolts (use grade 8 bolts with split lock washers) to 35 ft. lbs. The absence of the gasket will allow direct metal-to-metal contact, which keeps the bolts securely tight, with the silicone sealant filling in any imperfections between the two metals, eliminating oil leaks. By the way - I've always preferred to use clear RTV silicone adhesive sealant for three reasons: Due to metal warpage (which is unavoidable in most cases), gaskets don't always seal the irregularities and imperfections between mating surfaces, especially thin metal covers; being it's an adhesive, it bonds parts together, forming a leak-proof seal; and being it's clear, a thin bead of silicone makes for a clean and professional-looking repair job. When applied sparingly, it can't be easily seen or noticed between the parts.

On a Cub Cadet garden tractor, the only thing that fastens the engine block to the tractor frame is the oil pan. When choosing which oil pan material to use for competitive pulling, an OEM Kohler cast aluminum oil pan can be safely used on a stock pulling tractor that will not run over 4,000 RPM. It's best to install stainless steel Heli-Coil thread inserts in the mounting holes of an aluminum oil pan to prevent stripping the soft threads. And a cast iron, billet aluminum or machined steel oil pan should be used on an engine that will operate at very high RPM or at wide open throttle.

On a Kohler competition pulling engine that turns well above 4,000 RPM, at high RPM or at wide open throttle, the oil pan could loosen because the gasket acts like a cushion between the engine block and oil pan. At high RPM, normal engine vibration (caused by crankshaft side thrust, which is unavoidable in a single cylinder engine) can cause the engine block and oil pan to "shift" against each other a few thousands of an inch, allowing the gasket to flatten out overtime. When this happens, the bolts that fasten the pan to the block loosens. But the bolts don't actually rotate to loosen, they just lose their torque or tightness against the pan because of the flattened gasket. Which could crack or break the oil pan on one corner where the metal is thin and weakest. And applying liquid threadlocker on the oil pan retaining bolt threads will not help because if the gasket flattens out, although the bolts will not rotate to loosen, the oil pan will still loosen.

FYI - If oil leaks from an engine, transmission/transaxle or steering box, causing an oily mess on a concrete floor, mineral spirits (paint thinner) can be used to dry out the oil. Just pour some thinner on the oil, use a broom to thoroughly mix the thinner with the oil, and eventually the oil will dry with no signs of it ever being on the floor. Because of its low volatile flammability, paint thinner also works great as a cleaning solvent, which is used to clean oily or greasy mechanical parts.

By the way - it's a good idea to use split lock washers on ALL fasteners, to prevent other parts on the tractor from becoming loose later. And if you're concerned about driveshaft misalignment or clutch pin binding when not using an oil pan gasket, install a 1/32" (.030") thickness steel shim at each mounting hole between the oil pan and tractor frame. This will maintain proper driveshaft alignment with the engine so the clutch parts will last longer. So if somebody recommends using an oil pan gasket on a competition pulling engine that's going to turn well above 4,000 RPM, don't do it! Don't take chances! You could be sorry. Because sometimes listening to the wrong person can be very costly.

The Cub Cadet "Quiet Line" rubber ISO-mounted engine garden tractor models 680, 800, 1000, 1200, 1250, 1450, 1650 are notorious for cracking the cast aluminum oil pan because the pan fastens to two rails, which are independently mounted on rubber and are isolated from the main tractor frame. If the oil pan bolts aren't securely tightened, and due to normal engine vibration, sometimes the pan will develop a hair-line crack or break off at the corner, where the metal is the weakest, especially with an oil pan gasket. I've also seen them crack and . The same can happen with a cast iron oil pan. What happens is when a gasket is used, and when the pan bolts are tightened, the person who assembled the engine tightened the bolt on the corner on the PTO end of the block, then tightened the opposing bolt at the flywheel end of the block, and then tightened the other two remaining bolts. The first bolt that was tightened crushed the gasket, which caused a small, hair-line crack in the corner of the pan. Some people torque them with a gasket the wrong way. The correct sequence for torquing oil pan bolts is to lightly tighten one bolt on the flywheel end, then lightly tighten the bolt at the opposite corner on the PTO end, then lightly tighten another bolt, then lightly tighten the last bolt. Finally, torque each bolt to 35 ft. lbs. This procedure distributes equal pressure of each bolt without bending, warping or cracking the pan. Or better yet, just use clear RTV silicone adhesive sealant with no gasket. With no gasket, the pan will make direct contact with the block and they're be no bending, warping, cracking or breaking of the pan when the bolts are securely tightened. By the way - I've always preferred to use clear RTV silicone adhesive sealant for three reasons: Due to metal warpage (which is unavoidable in most cases), gaskets don't always seal the irregularities and imperfections between mating surfaces, especially thin metal covers; being it's an adhesive, it bonds parts together, forming a leak-proof seal; and being it's clear, a thin bead of silicone makes for a clean and professional-looking repair job. When applied sparingly, it can't be easily seen or noticed between the parts.

Identification of Kohler Engine Blocks -

Garden tractors that originally came from the factory with a straight or narrow base Kohler engine block are: IH-built and MTD-built Cub Cadet garden tractors, J.I. Case, John Deere (models 112, 110 and early model 210 with the Kohler K241 engine. Model 112 serial number 100,001 – 250,000, model 110 serial number 250,001 and up with the Kohler K241 engine, and 210 up to serial number 95,261), some Ford, some Jacobsen and Springfield. (The oil pan used on the John Deere and Springfield Kohler-equipped garden tractors are made of cast iron, identical to the early Cub Cadet/K241 flat bottom oil pan.)

And garden tractors that originally came from the factory with a flanged or wide base Kohler engine block are: Ariens, Wheel Horse, some Ford, some Jacobsen, Gravely, New Holland, Sears Suburban, Engineering Products Co. (Economy models) and Allis Chalmers. No Cub Cadet garden tractor originally came with a wide base Kohler engine block.

A flanged or wide base single cylinder Kohler engine block is made for the wide or large [2 quart] rectangular oil pan. These blocks can be converted for use with a narrow Cub Cadet garden tractor (or certain models of John Deere) oil pan, so the engine can fit inside the frame rails of a Cub Cadet garden tractor. Below is how to do the conversion.

An oxy-acetylene cutting torch can be used to cut off the flanges. When doing so, cut from the bottom of the block and position the flame at an angle (away from the block) so it won't get the block itself too hot. Fasten an angled plate on the block to guide the torch so it will perform a straight cut. After cutting off the flanges, to prevent possibly cracking the block, don't use water to cool the heated area! Allow the block to air-cool. For appearance, grind away any protruding metal or slag.

Or a portable plasma cutter (50+ amp models works best for thicker metal) can be used for quick and easy cutting off the flanges. Again, fasten an angled plate on the block to guide the cutting tip so it will perform a straight cut. The block shouldn't be too hot afterwards with the plasma cutter. If it is, to prevent cracking the block, don't use water to cool the heated area! Allow it to air-cool. For appearance, grind away any protruding metal or slag.

If a cutting torch or plasma cutter isn't available, then a vertical/horizontal bandsaw or a reciprocating saw (saw-saw; takes longer and require more effort) with a metal cutting fine-tooth blade can be used to cut the flanges off the block. Use caution doing it this way! The block must be held securely in the correct position to prevent binding of the blade and/or cutting through something else on the block. When finished cutting off the flanges, for appearance, grind away any protruding metal.

After cutting off the flanges, if there's oil fill/level check openings on each side of the block, the angled part of the opening will need to be ground flat, and a couple of 1/2" x 1/2" x 1-3/8" long steel stock pieces will need to be welded into the notches (see below Ê). After the welding process, for the oil pan to lay flat against the block, place a machinist straight edge against the bottom of the block and if necessary, use a large flat file or lightly grind the steel and/or weld so it's flush or even with the bottom of the block.

IMPORTANT! Use a (preferably new) 3/8-16 NC TAPER hand tap to cut new threads in the holes that's present in the block. (A taper tap removes less metal during the cutting process, making cutting new threads much easier and less chance of breaking the tap off in the hole. Plus, it's self-aligning with the hole. It won't cut the threads "to one side" or cocked.) After cutting the threads the entire depth of the holes, recut them with a PLUG hand tap so the threads on the bolts will go deeper. (A plug tap is also useful for cleaning threads.) If there are no holes, use a narrow oil pan as a template, and a 3/8" transfer punch to mark exactly where the holes need to be, then drill the holes and cut the threads.

Removing a Broken-Off Tap - A threading tap that has broken off in an engine block or metal casting can be very difficult to remove. About all I can tell you is to either take your block to a reputable machine shop to have the tap removed, or go here and try to do it yourself: https://www.google.com/?gws_rd=ssl#q=removing+broken+tap+from+hole. Actually, it's best to use a TAPER hand tap to cut new threads and clean out existing threads. If used correctly, a TAPER tap is less likely to break off. Click or tap here to learn how to cut new threads, the professional way.

Install an oil pan that's made for a narrow base engine block, such as a Cub Cadet garden tractor or certain models of John Deere garden tractors. (See below Ê)

For pulling applications, apply a thin bead of clear RTV silicone adhesive sealant when fastening the pan to the block. Otherwise, for general lawn and garden use, use a gasket and the silicone to lessen the chance of any oil leaks. By the way - I've always preferred to use clear RTV silicone adhesive sealant for three reasons: Due to metal warpage (which is unavoidable in most cases), gaskets don't always seal the irregularities and imperfections between mating surfaces, especially thin metal covers; being it's an adhesive, it bonds parts together, forming a leak-proof seal; and being it's clear, a thin bead of silicone makes for a clean and professional-looking repair job. When applied sparingly, it can't be easily seen or noticed between the parts.

How to Weld Steel to Cast Iron...

First of all, being cast iron is porous, it soaks up oil like a sponge. (This is why all cast iron Cub Cadet garden tractor transaxles are painted on the inside, to keep oil from seeping through the case to the outside.) Anyway, the area that's to be welded first must be heated with an acetylene torch to burn the oil out of the iron. Be careful not to get the iron too hot! Overheating could cause it to crack. Heat it just enough so all the oil evaporates and the iron appears dry.
Grind the edges of the cast iron and steel pieces creating a "V" shape area so the weld will lay into this and not be "lumped up." This will help bond the two pieces together better.
Use a wire-feed MIG welder with mild steel welding wire or a stick welder with a nickel rod, and weld the steel to the cast iron like you would with ordinary steel to steel. Allow the welded area to air-cool. Don't apply water to the weld! Doing this may separate the weld from the iron.

To identify a Cub Cadet garden tractor oil pan, first of all, they're exactly 1-1/16" tall. The pan to tractor frame holes measures exactly 4-15/16" x 7-5/8". From the base of the Cub Cadet pan to the centerline of the crankshaft for the K241-K361 Kohler engines, the measurement (height) is exactly 4.750" (4-3/4"). And with a wide base oil pan, it measures 6.125" (6-1/8"). These measurements are with the compressed (.030" thickness) oil pan gasket installed.

Cub Cadet garden tractor oil pans have either a flat bottom or deep sump. The flat bottom pans are originally made for the K241 engine, but will work with no problem on the K301, K321, K341 and K361 engines, but half of the oil dipper on the connecting rod must be cut off. The deep sump ones are suitable for stroker engines. The flat bottom pan holds 1 quart of oil, and the deep sump one holds 1-1/2 quarts. If a deep sump oil pan is used on an engine that originally came with a flat bottom oil pan, the oil dipper on the connecting rod will be too short and won't be able to splash as much oil to thoroughly lubricate the parts.

The length of the dipper on the connecting rod when shortened must be no shorter than 1-5/8" in length, when measured from the bottom of the rod cap to the end of the dipper. And a short dipper will help to increase the engine power. If a K241 Kohler engine has a small, flat bottom Cub Cadet oil pan, the connecting rod has short dipper. But if it has a large, wide base pan, the rod has a long dipper. The K301-K361 engines all come with a deep sump oil pan, as well as a large, wide base oil pan. Therefore, their connecting rods have a long dipper.

If it's an oil pan that's designed for a Cub Cadet garden tractor, then the shallow and deep oil pans are the same (except for the oil capacity) and will fit virtually all models of Cub Cadet garden tractors. A longer dipper on the connecting rod is not really necessary, but it will provide better lubrication if the oil level were to get low. And the oil level full mark on the oil dipstick will register the same regardless of the type of oil pan is used.

If an oil pan has the drain plug in the wrong location, another drain plug can be installed by finding an area on the pan where the metal is thicker than the surrounding area. These places are specially made by the factory to drill and cut threads for the oil drain plug.

Oil Refill Quantities for Kohler Engines - IMPORTANT: Make sure the oil dipstick is calibrated correctly! *NOTE: Add 1/8 quart for a competition pulling tractor that have a single cylinder longitudinal engine with a lowered front-end.

The best way I found to clean old gasket material from the oil pan and other flat surface engine parts is with a large flat coarse file with the pan (or part) gently clamped in a large bench vise. Be careful not to file off the metal!

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 oil capacity for your gear drive transmission, transaxle, right angle gearbox, or garden tiller sealed chaincase or gearbox, well, the transmission, transaxle, right angle gearbox, chaincase or gearbox is full when oil runs out of the oil level check/fill plug hole that's located halfway [of the axles] on the side, front or rear of the transmission, transaxle, right angle gearbox, chaincase or gearbox. All gear drive garden tractor transmissions, transaxles and gearboxes fill this way. The ring gear in transmissions and transaxles picks up the oil and slings it on the upper gears, shafts and bearings to lubricate them. Due to friction between the gear teeth in transmissions, transaxles, right angle gearboxes, and garden tiller gearboxes, SAE 90 weight gear oil must be used. And due to less friction of the roller chain(s) on the sprocket teeth, 10W30, 10W40 or SAE 30 weight heavy duty motor oil can be safely used in all sealed chaincases.
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.

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.

To place an order, please call the number below Ê or send an email with your name, complete and correct postal address and phone number and so I can figure the total with shipping cost and USPS Tracking. For payment options for parts ordered or services performed, or to make a donation to my websites, I accept cash (in person), USPS Postal Money Orders, cashier's checks, business checks, MasterCard, VISA, Discover, American Express (please add 2.5% to the total for the credit/debit card processor's surcharge), Western Union Money Transfer or MoneyGram Money Transfers. (If a part for a specific purpose is special ordered, your debit/credit card may be charged for the full amount or as a deposit right after your order is placed; please do not send your debit/credit card information in email!) Or you can pay A-1 Miller's through PayPal. (My PayPal account name is my email address. And be sure to mention in PayPal a description of what the payment is for.) If sending a money order, please include a note in the envelope with your name, complete and correct postal address, phone number and a description of what the payment is for. My mailing address and phone number are below Ê . I'll make a note of your order, and I may have to order some of the parts, which should take a few days to come in, but I will send the parts to you as soon as I have everything in stock after I receive your payment.

IMPORTANT - When sending your part(s) to A-1 Miller's for rebuilding or repair, package everything securely so the item(s) won't get damaged in shipping and please include a note in the box with your name, mailing address, phone number (in case I have any questions) and a description of what you want done. When shipping heavy parts, it's best to put a slightly smaller box inside a larger box, to double the strength and integrity of the package. Because the clumsy "gorillas" or incompetent and uncaring workers that work for certain delivery services mishandle the heavy packages and don't care. And when the work is completed, I'll either call or email you an invoice with the total including shipping & handling.

Payment Options and We Ship to Canada and Worldwide
Item(s) in a package or cushioned envelope weighing less than 1 lb. is sent by US Postal Service Airmail Letter Post for a 4-7 days delivery. Packaged item(s) weighing over 1 lb. and up to 66 lb. is sent by US Postal Service Airmail Parcel Post for a 4-10 days delivery. I cannot use the US Postal Services' Flat Rate Priority Mail envelopes and boxes to ship outside U.S. territories. Item(s) weighing over 67 lbs. or more is sent by FedEx Ground or equivalent services. We try to keep our shipping cost to customers within reason. Therefore, we don't ship our products in a fancy-looking package with our company name and/or logo on it because most customers will just toss it in the trash after they remove the contents. And being there is no USPS tracking number outside the US, all I can do is make sure I write your address correctly on the customs form and on your package.

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 oil capacity for your gear drive transmission, transaxle, right angle gearbox, or garden tiller sealed chaincase or gearbox, well, the transmission, transaxle, right angle gearbox, chaincase or gearbox is full when oil runs out of the oil level check/fill plug hole that's located halfway [of the axles] on the side, front or rear of the transmission, transaxle, right angle gearbox, chaincase or gearbox. All gear drive garden tractor transmissions, transaxles and gearboxes fill this way. The ring gear in transmissions and transaxles picks up the oil and slings it on the upper gears, shafts and bearings to lubricate them. Due to friction between the gear teeth in transmissions, transaxles, right angle gearboxes, and garden tiller gearboxes, SAE 90 weight gear oil must be used. And due to less friction of the roller chain(s) on the sprocket teeth, 10W30, 10W40 or SAE 30 weight heavy duty motor oil can be safely used in all sealed chaincases. 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.)

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.
