Kohler K301 Piston
 

Does anyone know where to get Kohler K301 Style D Piston Rings? I'm trying to do a refresh of my K301 by honing the top end and installing new rings. I got some Standard rings online and they are too thick for my piston. I believe I got a Style D and I can't find any rings that are not 100$ online. I can't guarantee that it will fit my pitson.

I have bought a bunch of stuff from these guys over the years.

Have always had good luck with the service.
and the parts.

I can't even find a part number for the Piston Rings for the different Piston that is offered on the K301. It's hard to order parts if the Kohler Service Manuel dont even have the part numbers.

You will not find part #'s in a service manual.
Use the parts manual look up site

Service Manuals usually don't list part numbers.
Parts Manuals list part numbers.
Kohler Parts Manuals require the Engine Spec and Serial Number from the tag on the
engine for accurate parts i.d. numbers.
What are your spec and s.n. numbers?

No tag left on the motor unless its stamped or cast into the block some where.

OK, let's narrow this down a bit here,
We need some answers

What tractor is this engine in?

What color is it?

Manual PTO or electric?

Over the years kohler has changed things as you know.
I doubt they have rings for an old style piston (but someone might)
Most ppl replace the piston and rings together as they wear together.
If you insist on "freshening" the cylinder as you say, without going oversize
or at least going with a new piston and rings, you might just clean the carbon on the head/piston and leave it be.

When going to a new piston/rings that is of standard size. you do not want to "hone" the cylinder as it is already worn bigger than it should be.
A light deglazing is advisable as it makes a light cross hatch pattern in the wall to promote new ring sealing.
But remember the old rings are conformed to the out of round cylinder.
and the new ones are perfectly round, and it could use more oil than it did before till the rings are seated.
And if there is any ring groove at the top of the cylinder, that is not removed,
at minimum the top ring is going to be flexing badly and at worst it will break.
There are suppliers out there that sell STENS which are good parts
As well as venders like "I save Tractors" and the already mentioned "bakt4kids"

just trying to be helpful here for those that might not have been around when we actually rebuilt things and not threw them away and they worth rebuilding. :beerchug:

I agree with Ol' George more with doing a proper bore with a new piston & ring set. Just setting in new rings in an old bore is potentially asking for more trouble than you anticipate.

I guess I will need to take it to a machine shop.. or try to find another motor.. i just dont have $700+ to drop on a complete rebuild. Its cheaper to find another motor thats running good.
