Piston
Material
Disassembly
- Remove the piston rings from the piston.
- Discard the piston rings.
- Remove the 2 piston pin retainers and the piston pin.
- Discard the 2 piston pin retainer clips.
- NOTE: If the piston and/or connecting rod are being installed
new, the piston rod orientation marks and the arrow on the top of the dome
of the piston should be facing toward the front of the engine block.
NOTE: If the piston and connecting rod are to be reinstalled, they must be assembled in the same orientation. Mark the piston orientation to the connecting rod for reassembly.
Separate the piston from the connecting rod.
- Clean and inspect the piston and connecting rod. For additional information, refer to Section 303-00.
Assembly
- Align the piston-to-connecting rod orientation marks and position the connecting rod in the piston.
- Lubricate the piston pin and pin bore with clean engine oil.
- Install the piston pin in the piston and connecting rod assembly.
- Install the new piston pin retaining clips in the piston.
- The piston pin retaining clip gap orientation must be toward the top or dome of piston.
- Lubricate the piston and the new piston rings with clean engine oil.
- NOTE: The piston compression upper and lower ring should be
installed with the "O" mark on the ring face pointing up toward the top of
the piston.
Install the piston rings onto the piston as shown.
- Center line of the piston parallel to the wrist pin bore
