Fitting Pistons
- Check cylinder bore for damage, wear and taper. See CYLINDER BLOCK under OVERHAUL. See CYLINDER BLOCK table under ENGINE SPECIFICATIONS to determine if block must be rebored.
- Pistons are available in .0098" (.25 mm) and .0197" (.50 mm) oversizes. Check outside diameter of piston. Measure at a point 1.04" (26.5 mm) from bottom of skirt and at 90 degrees to pin bore.
- Standard pistons are available in 2 sizes. Piston diameter is determined by numerical mark ("1" or "2") stamped on piston crown. Cylinder bore diameter is determined by mark (Red or Blue) on cylinder block.
- When installing piston into cylinder, ensure piston numerical mark matches cylinder bore numerical mark to provide correct piston-to-cylinder clearance. See Fig 1.
