Fitting Pistons
- Measure piston diameter at 90-degree angle to piston pin, on piston pin center line. Measure cylinder bore diameter 2 1/2" below cylinder block deck. Determine piston clearance.
- If piston clearance is not within specification, replace piston and/or machine cylinder bore as necessary. See CYLINDER BLOCK table and PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS at end of article.
