Piston Pin Bore
Measure the pin bore. The maximum diameter is 40.025 mm (1.5758 inch). If the bore is over limits, replace the piston.
Piston Pin Diameter
Inspect the piston pin for nicks, gouges and excessive wear. Measure the pin diameter. The minimum diameter is 39.990 mm (1.5744 inch). If the
diameter is out of limits, replace the pin.
CONNECTING RODS
Inspect the connecting rod for damage and wear. The I-Beam section of the connecting rod cannot have dents or other damage. Damage to this part
can cause stress risers which will progress to breakage.
Connecting Rod Pin Bore
Measure the connecting rod pin bore. The maximum diameter is 40.042 mm (1.5764 inch). If out of limits replace the connecting rod.
ASSEMBLY
NOTE: The piston is symmetrical and can be installed to the connecting rod in either direction. It is good practice to re-install the piston in the same
orientation as it was removed.
