CYLINDER BLOCK ASSEMBLY
Note. During disassembly, match mark components for reassembly reference.
Piston & Connecting Rod Assembly
- Before removing rod cap from crankshaft, measure and record rod side play. See «CONNECTING RODS»(ref-3925-S15213754812000052600000) table under ENGINE SPECIFICATIONS. Before removing connecting rods, measure and record connecting rod bearing oil clearance. See «CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS»(ref-3925-S02779268342000052600000) table under ENGINE SPECIFICATIONS.
- Before separating piston from connecting 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»(ref-3925-S40324146772000052600000) 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. (Scheme 18) Install piston and rod assembly so "F" mark on side of piston is facing front of engine.
