Piston: Service and Repair
Disassembly And Assembly
DISASSEMBLY
NOTE: Any piston rings that are removed from piston should be discarded and replaced with new rings.
1. If piston ring replacement is required, use a suitable piston ring expander to remove two compression rings. Remove two oil ring rails and
expander by hand.
WARNING: Cover the end of the pin bore with a hand or shop rag when removing the retainer ring since it has a tendency to spring out.
Eye protection should be worn.
2. Using O-Ring Tool T71P-19703-C, remove the two piston pin retaining rings.
3. Gradually heat the piston to approximately 100°C (212°F).
NOTE: The piston and piston pin (6135) are a matched set. Keep pistons, piston pins, rings, connecting rods and connecting rod bearings
together in proper cylinder order.
4. Using Piston Pin Tool D81L-6135-A or equivalent, press piston pin from piston and connecting rod.
REASSEMBLY
