My 214's K321AQS has a couple of gouges that will probably put it over the .030 max rebore size. It looks like it will be a candidate for a new sleeve. Does anyone have any experiences with re-sleeving a K series Kohler (good or bad)? Would you recommend sleeving to the original bore or going .010, .020, or .030 over? Thank you in advance.

I've had two K341's re-sleeved at a NAPA machine shop. Excellent work! Definitely go to stock so you will have room for a rebore if needed. It was about 5 or 6 years since my last one & the sleeve costs around $100 total... labor & sleeve. Piston not included of course. I was very satisfied & both engines running strong still today.

I don't mean to hijack this thread, but I have a related question: I have a K241 that has already been re-bored twice. The PO said that his mechanic/machinist said it couldn't be done again. My question is what is the maximum size the cylinder can be bored to? I would like to sleeve it, but the machinist that I talked to said that there may not be enough "meat" left to true the bore before sleeving. I haven't been into the engine yet, so I do not have any dimensional info for it. Just thought someone might know off the top of their head.

Everywhere I have looked says it can be bored to .030 over. Check out Randy Miller's site Vital Information about Engine Rebuilding, Buildups and Modifications as he states a K241 could also be bored out to use a K301 piston, even up to .030 over.

jd.,

We bored a k301 out in our pulling tractor to about .060 over and found a chevy piston that would work just fine.Dad did this in 1971 and we pulled for about 4 more yrs.. Also using the same tractor to mow and snowblow with. It was stolen about 10ys. ago, still unning good with that same block and piston.

Brian

P.S. -I may have a spare block for a 214 in my stuff, if your interested.

Brian,

I'll wait for the verdict from the machine shop. If I don't like what they have to say, I may be interested. Thank you! Jeff
