Disassembly and Assembly of Sub-Assemblies
Special Tools:
Disassembly
1. Remove the two retainers from the piston pin bore.
2. Gradually heat the piston assembly to approximately 100°C (212°F).
3. Use the Piston Pin Tool to press the piston pin out from the connecting rod and piston assembly.
4. Remove the connecting rod from the piston.
5. Clean and inspect the connecting rod and piston.
Assembly
1. Lubricate the piston pin and piston bore.
^ Use Motorcraft Super Premium SAE 5W-30 motor oil XO-5W30-QSP or equivalent meeting Ford specification WSS-M2C153-G.
2. Install a new retainer ring on one side of the piston pin bore.
3. Gradually heat the piston to approximately 100°C (212°F).
4. Note: The connecting rod can be installed in either direction.
Position the piston pin in the bore aligned with the connecting rod bore.
5. Use the Piston Pin Tool to press the piston pin into the piston and the connecting rod until the pin hits retaining ring.
6. Install a new retainer ring on the other side of the piston pin bore.
7. After assembly, make sure the connecting rod swings smoothly on the piston pin.
