Replacing engine rings on a 108, advice please!

2 posts in this topic

My Cub Cadet 108 fitted with a Kohler K241 engine is needing a set of rings. The engine is breathing oil smoke from the oil breather and it uses a bit of oil. As far as I know the engine has never been open before. As there are no other problems do you think that I could just fit a new set of rings to the engine. Or do I need do more? The engine starts easily and runs with good power so I am presuming that a worn or broken oil ring may be the problem.

Thanks in advance for any advice. Denis.

Odds are your 108 will more than just a set of rings, The engine needs to disassembled and the cylinder bore needs check.

The cylinder will need bored at least .010. The crank may need turned .010 under. The valve guides may need replaced.

Cost to rebuild is $350 to $600 depending on how much you can do.

I rebuild 3-6 K series engines a year. These are the problems I see when I rebuild a engine for someone.
