Piston & Rod Assembly
- Ensure piston, connecting rod and connecting rod cap are match marked for reassembly reference. Hold piston/rod assembly with connecting rod positioned horizontally. Pull connecting rod upward. Release connecting rod and ensure connecting rod drops freely. Replace piston or piston pin if connecting rod fails to drop freely.
- To remove piston from connecting rod, properly support piston in hydraulic press. Press piston pin from connecting rod. Replace piston pin or connecting rod if pressure required to remove piston pin is less than 880 lbs. (400 kg).
- Ensure piston pin diameter and pin-to-piston fit are within specification. See «PISTONS, PINS & RINGS»(ref-49161-S09126852432001011500000) under ENGINE SPECIFICATIONS.
- Ensure connecting rod bend, center-to-center length, crankpin bore and piston pin bore diameter are within specification. See «CONNECTING RODS»(ref-49161-S27197066692001011500000) under ENGINE SPECIFICATIONS.
- To assemble piston on connecting rod, ensure front mark on piston ("L" or "R") and connecting rod are facing upward. (Scheme 25) Ensure piston is properly supported in hydraulic press. Press in piston pin. Replace piston pin or connecting rod if force required to install piston pin is less than 880 Lbs. (400 kg). Ensure connecting rod pivots freely.
