putting in a sleeve seems like a lot of specific, detailed machine work, not to mention honing. do you pre hone the sleeves?
Yes, it's not rocket science. Match a piston to a sleeve ahead of time. Just hard work and you beat the replacement sleeve back in with BFH and heavy steel plate. The flats on the sleeves determine if it's in right. No machine work needed.
makes sense, but i never would have thought it could be done that easily…
No machine work needed.
