Fitting Pistons
- Measure piston skirt diameter .08" (2 mm) above bottom of highest point on piston skirt, at 90-degree angle to piston pin. If piston diameter is not within specification, replace piston. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS.
- Measure cylinder diameter in 3 places: .47" (12 mm) from top of bore, .47" (12 mm) from bottom of bore, and near center of bore. If cylinder diameter or taper is not within specification, rebore cylinder. See CYLINDER BLOCK table under ENGINE SPECIFICATIONS.
- If clearance between piston and cylinder bore clearance is not within specification, replace piston and/or machine cylinder bore. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS.
