I am about to embark on a field overhaul of an IO-540-AB1A5. The donor engine belongs to my hanger mate. He purchased the airplane new 17 years ago, it has no damage history and currently airworthy (although it has reached 2,100 hrs).
I have a list of mandatory parts required for the overhaul. During the process I will be upgrading it to 260HP -D4A5. That requires new counterweights, rods, pistons and pins. I'd expect it will get a new cam and cylinders as well.
I read an article by one of the engine shops, that they habitually check all new parts for dimensions before installation. The point that really caught my eye was that they reject 30% of new cylinders. Can that really be correct?
