bore. Rings are made of cast iron; top ring has a chrome edge. Available
in STD, .010", .020" and .030" oversizes. NOTE: The model K141 Kohler
engine will need to be bored to 2.9375" (2-15/16") to accept this bigger
piston and rings because the piston/rings for the 2-7/8" bore are no longer
available. And being the wrist pin is centered, this piston can be installed
in either direction. $50.00 each, plus shipping & handling.
NOTE: High-quality OEM-type ring sets, pistons and piston/rings assemblies are also available for other makes & 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 use a billet connecting rod of the correct length with an aftermarket piston (Arias or JE) that has the right 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 an OEM piston and rod, these parts will not interchange with a longer-than-stock billet rod or with an OEM-type of piston of a different compression height, and vice-versa. |
| NOTE - We can get complete engine rebuild kits, but a kit cost us more than if we were to order the parts individually. So please email us or call us with a list of which parts you need, and we'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 us and we'll see if we can get it at a reasonable price. Please contact us 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.
If this cannot be done, then the rod is scrap metal. |
8hp Connecting Rod -
New STD size 8hp (K181 & M8) K-series and Magnum flathead engine connecting rod. Replaces Kohler part # 41-067-10. This is a plain aluminum bearing surface rod. Bearing inserts are not available for this particular rod.

| 10hp Connecting Rod -
12hp and 14hp Connecting Rods -

18hp OHV, OEM Stock Camshafts and Used Governor Gears - Top of page
Used OEM Crankshafts, Balance Gears and New Main Bearings -
10hp, 12hp,
14hp and 16hp K-series and Magnum flathead single cylinder engine crankshafts.
These cast iron cranks are a genuine Kohler part, they're used, but in
good 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 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 dimensions of the PTO shaft on your crankshaft so we can match
it to one that we may have in stock. Measure the diameter and length from
the gear teeth. [When available.]

New main crankshaft
bearings for 7hp and 8hp Kohler K-series and Magnum single cylinder cast
iron flathead engines. These are specifically designed to provide maximum
performance by means of precise ball implement selection. Heat treated. Good
for high performance use. Made in China, but has the same quality as OEM
Kohler bearings for long wear. Dimensions: 1.18" i.d. x 2.44" o.d. x .62"
width. $15.00 each, plus shipping & handling. Part # 150-960
New 8 ball main crankshaft bearings for 10hp, 12hp, 14hp, 16hp (flatheads) and 18hp (OHV) Kohler K-series and Magnum single cylinder cast iron engines. These are specifically designed to provide maximum performance through precise ball implement selection. At higher rpms, bigger balls run cooler which create less rolling resistance than bearings with smaller balls. Heat treated. Good for high performance use. Made in China, but has the same quality as OEM Kohler bearings for long wear. Replaces Kohler part # 235376. Dimensions: 1.57" i.d. x 3.54" o.d. x .90" width. $20.00 each, plus shipping & handling. Part #150-973 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. |

Complete Exhaust Header Pipe Kits - We offer
three types of exhaust header pipe kits.
Top of page
The two holes that's to be drilled and tapped
for the header pipe in the exhaust port of the engine block should be performed
on the table of a large milling machine by an experienced machinist. The
holes are to be drilled with a letter "F" or 17/16" drill bit, and about
1-1/4" deep. Then the threads cut perpendicular to the exhaust flange with
a 5/16-24 NC tapered tap. Use plenty of oil and go slow to prevent from breaking
the tap off in the block. Because if it breaks off, it'll be terribly hard
to remove.
Complete and
ready to bolt on header pipe kit for 10hp, 12hp and 14hp Stock and Stock-Altered
Kohler engines with stock size valves and with or without a working
governor.
Kit includes one 1-3/16" i.d. x 1-5/16" o.d. pipe; measures approximately 7" from the block and approximately 19" tall; has a 90° semi-mandrel bend; mounting flange; two Allen head stainless steel mounting bolts and an anti-vibration brace. Galvanized-coated steel. Very shiny, resists rust. Designed for use on Cub Cadets and most other makes & models of garden tractors with a 10, 12 or 14hp Kohler K-series or Magnum engines. This pipe has a flange that securely fastens to the engine block with two furnished 5/16" diameter coarse thread (5/16-18 NC) Allen head bolts. If your block don't have the two threaded mounting holes, then they will need to be drilled and tapped to accept the pipe. There is no other way to fasten this pipe to the block. Comes with no mounting gasket. Use silicone sealer instead. An adapter is NOT needed for this pipe because the flange is small enough to clear the governor lever. Shipping weight is 4 lbs.

NOTE: To fasten
the anti-vibration brace to the pipe, with an engine turning no more than
4,000 rpms, it's safe to use a stainless steel automotive radiator hose clamp.
But if an engine is going to run at
wide
open throttle, it's best to use a 1-1/2" automotive "U" shaped muffler
clamp. These are available at any auto parts store. By the way - the
anti-vibration brace is very important because we think there's nothing more
embarrassing and being disqualified than having a welded-on header pipe break
off at the weld while the tractor is pulling down the track.

| Engine Rebuilding Service -
We rebuild anything from ordinary stock engines up to high performance engines. We can rebuild your engine however you want. Just tell us know how you're going to use your tractor or equipment and we'll build your engine to suit your needs. If you wish to have us to rebuild or build-up your engine, we'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 we can give you an estimate on the cost. We'll build your engine to the limit according to the rules, not less than what the rules allow. Whenever we rebuild or build-up an engine, and if you wish to do so, we do whatever it takes so it'll produce the factory-rated horsepower or the maximum horsepower and torque, and last a long time. We go beyond what the repair manual says to do. We can get all the parts needed, too. We can build your engine so it'll be legal for the class you plan to pull in.

NOTES:
If you decide to ship your
engine to us, enclose it in a sturdy wooden crate with cushioning surrounding
the engine, and the crate securely fastened onto a wooden pallet. Do not
use a cardboard box! 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 heavy 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 us in person, sit it in an old
tire to keep it from moving around during transportation. And please let
us 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! Their 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.
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) and the crated weight of a typical complete 10-16hp Kohler engine (145 lb.).
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. Contact your local FedEx Ground for more details. 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 plastic crate, or a sturdy cardboard box. 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. Or if you'd prefer to deliver your engine or transaxle
personally to us, we're located at 1501 W. Old Plank Rd. |

| Warranty: Since the products we sell are used under extreme
high-performance conditions, there is no "100% warranty" on most parts, engines
or engine rebuilds. If you do have a problem with anything we sold or repaired
for you, please feel free to contact me. Parts ordered from this website
should be installed and used by persons that are familiar with mechanical
parts and their proper use and installation. Consult our garden tractor tips
and tricks web pages of the parts for its proper use and mechanical requirements.
Customer assumes responsibility for maintaining products and/or equipment
in safe operating condition.
Warranty on our engines and engine rebuilds depend on what goes wrong with the engine. Typically, if the engine is taken care of (regular oil changes, proper ignition timing, valve adjustments and use of correct octane fuel), our engines are quite reliable and will last for many years. So if an engine has been taken care of, we will stand behind our engines for a period of one pulling season or one mowing season. |
