Fitting Pistons

  1. With piston removed from crankcase, check cylinder bore for taper or out-of-round. If taper or out-of-round exceeds 0.008", cylinder bore must be bored to next oversize.
  2. Pistons and rings are available in oversizes ranging from 0.010" to 0.060" in 0.010" increments.
  3. Check piston-to-cylinder clearance. A 0.0012" feeler gauge should require 2.2-5.5 lbs. tension, measured on a spring tension gauge, to be pulled out from between piston and cylinder wall.
