k241 re-sleeve?

[knoxy_14]

can a k241 be re-sleeved or only bored out? im working on taking the engine apart and noticed when its bottomed out i can almost see the whole ring and not sure if there is enough meat to to bore even .030 over

take it to the machine shop and have it checked, they will be able to measure it and tell you how far it needs to be bored.

yes i plan on doing that soon as i get a broken allen wrench out of the set screw out of the pto..... im just planning ahead of time lol

If it is STD bore, they will usually clean up @ .010,
if it is already .030 over then you can sleeve it or get another block which is usually less expensive.
There might be some after mkt. pistons bigger than .030 , I don't know.

i dont see any stamp on the piston im pretty sure its std but worried that the bottom of the cylinder is worn so much cant go 30 over since i can almost see the whole ring are all k241 blocks the same?

Well Don or Jon will know better than I , but I'm thinking you can bore it to a k301. Standard k241 bore is 3.25 k301 is 3.38. If possible I'd go that route vs sleeving it.

The Bore will wear the most right @ the top just under the first ring position,
not @ the bottom of the stroke.

when its topped out its actually isnt real bad its about the last maybe inch or less at the bottom and i noticed that the wrist pin is shot also i believe thats what its called or its the crank since i havent got it all torn down completely i cant tell that for sure all i know i can push the piston down a little bit while holding the crank still
