Camshaft, rocker arms were destroyed dut to lack of oil. Repaired. Pulled jug to clean out shavings in engine. I checked bore it was ok, piston ok. Rings looked good. Can i re-use old rings ,will they seal. Or should i just install new rings. STandard size?
yeap just bye sum new ones they are cheap and just have the cylinder honed for a good seal and break in of the new rings.just make sure you get the spec for the ring end gaps and index them correctly-corey-
You know, when I put my Prairie 400 back together I ordered a high compression piston. I sent the cylinder off to be bored, I packed up the whole thing so that the machine shop could endgap the rings for me. The guy said he checked them and they were exactly in spec. I was really impressed but it also brings into stark contrast the quality assurance of new manufacturing processes. It's old wisdom to have a ring endgap grinder handy whenever you rebuild an engine because old engines NEEDED to have the ring endgap filed. These new engines (and replacement parts) are to such a degree of accuracy that it's almost unnecessary to bother checking endgap unless there is some problem while putting the engine together.
good point but i dont always trust the manufactuers,they could have been made on a friday at 2:59:45 pm and quitin time is three lol.it never hurts to double check and make sure they are in spec-corey_
