Inspection
INSPECTIONNOTE: Inspect the piston, piston pin and connecting rod when they are at room temperature.
1. Measure the diameter of the piston pin.
Piston Pin Diameter:
Standard (New): 21.962 - 21.965 mm (0.8646 - 0.8648 inch)
Service Limit: 21.954 mm (0.8643 inch)
2. Zero the dial indicator to the piston pin diameter.
3. Check the difference between the piston pin diameter and piston pin hole diameter on the piston.
NOTE: Check the piston for distortion or cracks.
Piston Pin-to-Piston Clearance:
Standard (New): -0.0050 to +0.0010 mm (-0.00020 - +0.00004 inch)
Service Limit: 0.004 mm (0.0002 inch)
4. Measure the piston pin-to-connecting rod clearance.
Piston Pin-to-Piston Clearance:
Standard (New): 0.005 - 0.014 mm (0.0002 - 0.0004 inch)
Service Limit: 0.019 mm (0.0007 inch)
