Fitting Pistons
- Measure piston skirt diameter at 90-degree angle to piston pin. If piston diameter is not within specification, replace piston. See appropriate table under PISTONS, PINS & RINGS SPECIFICATIONS under ENGINE SPECIFICATIONS.
- Measure cylinder bore diameter at 3 places: near top of bore, bottom of bore and center of bore. If cylinder bore diameter or taper is not within specification, machine cylinder bore. See appropriate table under CYLINDER BLOCK SPECIFICATIONS under ENGINE SPECIFICATIONS.
- If piston-to-cylinder bore clearance is not within specification, replace piston and/or machine cylinder bore. See appropriate table under PISTONS, PINS & RINGS SPECIFICATIONS under ENGINE SPECIFICATIONS.
