  • MEASURE THE BORE BEFORE ORDERING - A caliper across the old piston crown settles which version of the engine you have, and it is the only test that does. Ordering by horsepower or by year is how the wrong part ends up on the bench, because the same machine was often built in more than one bore. The number this replaces is 503081501.
  • CHECK RING END GAP IN THIS CYLINDER - Not in the old one. Square the ring in the bore, measure the gap with a feeler, and check side clearance in the piston groove while you are there. A ring that is tight at operating temperature will break a land.
