- Standard service pistons are color-coded Red, Blue, and Yellow on dome of the piston. Measure the piston skirt diameter at a 90-degree angle to piston pin 1.62" (42.0 mm) below piston top. Replace piston if piston diameter is not within specification. See «PISTONS, PINS & RINGS»(ref-22905-S17158838792001011500000) table under ENGINE SPECIFICATIONS.
- Measure cylinder bore at 1/2" below top of piston travel and 1/2" above bottom of piston travel. Ensure piston clearance is within specification. See «PISTONS, PINS & RINGS»(ref-22905-S17158838792001011500000) table.
- If piston clearance is not within specification, choose a selective fit piston to bring piston clearance within specification. See «PISTONS, PINS & RINGS»(ref-22905-S17158838792001011500000) table, for selective fit piston sizes.
- If piston clearance cannot be corrected using a selective fit piston, bore all cylinders to nearest oversize.
