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, remove piston pin clip from both ends of piston pin. Using Piston Pin Driver (49 T011 001) and hammer, remove piston pin.
- Ensure piston pin diameter and pin-to-piston fit are within specification. See «PISTONS, PINS & RINGS»(ref-3917-S30775479782000052500000) table 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-3917-S32859507792000052500000) table under ENGINE SPECIFICATIONS.
- To assemble piston on connecting rod, ensure front mark on top of piston ("L" or "R") and connecting rod are facing upward. Install piston clip in piston groove at one end of piston. Apply oil to piston pin. From opposite side of piston, install piston pin until it contacts clip on opposite side. It may be necessary to heat piston to ease installation of piston pin. Install 2nd clip in groove. Ensure connecting rod pivots freely.
