Technical tip: Piston grooves vs. piston rings.
It is not difficult to determine whether a set of Hastings piston rings will fit a given piston. You must measure the height of the piston groove on the piston itself. The 2 upper grooves are for the compression rings, the lower groove is for the oil ring. In most cases, Hastings oil rings are the low-tension 3-piece flexible type. Ring heights are listed for reference.
Technical tip: Piston oversizes.
For each oversize, the cylinder bore increases by .010" (0.254mm). The standard cylinder bore is stated for reference.
