Fitting Pistons

  1. Measure piston skirt diameter at 90-degree angle to piston pin. If piston diameter is not within specification, replace piston. See PISTONS, PINS & RINGS SPECIFICATIONS  table.
  2. Measure cylinder bore diameter at the following 3 places: .47" (12 mm) from top of bore, .47" (12 mm) from bottom of bore, and near center of bore. If cylinder bore diameter or taper is not within specification, machine cylinder bore.
  3. If piston-to-cylinder bore clearance is not within specification, replace piston and/or machine cylinder bore.
