Fitting Piston Pins: Removal
- Remove bearing inserts from connecting rod and cap. Index mark pistons, pins and inserts (if reusable) to assure assembly with same rod. Press piston pin from piston and connecting rod using Piston Supporter (J-24086-20).
- Inspect and replace any piston pin showing signs of fracture, etching or wear. Check piston pin-to-rod bore fit. Check I.D. of connecting rod piston pin bore. If piston pin bore is larger than specification, piston and pin assembly must be replaced.
- Piston pins must fit into piston with light pressure. Ensure proper fit by honing or reaming piston pin bore to correct dimension. Lubricate pin and small end of rod bore with engine oil.
