Piston & Rod Assembly
- Note matching marks on top of piston and cylinder block deck surface. Before separating piston from rod, mark piston in relation to connecting rod. Check oscillation movement of piston and rod assembly (hold piston horizontally, lift rod and allow rod to drop by its own weight). If pin binds in pin bore (rod does not drop), replace piston and/or pin as necessary.
- To separate components, press piston pin out of piston and rod assembly, noting pressure required to remove piston pin. If piston pin can be pressed out with less than 1100 lbs. (500 kg) of pressure, replace piston and/or connecting rod.
- Ensure piston pin diameter, piston fit and rod fit are within specification. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS. Using 1100-3300 lbs. (500-1500 kg) of pressure, install piston pin through side of piston that has an "F" mark near pin bore. Install piston and rod assembly so "F" mark on side of piston is facing front of engine.
