Piston Pin: Testing and Inspection
INSPECT PISTON PIN OIL CLEARANCE
1. Using a caliper gauge, measure the inside diameter of the connecting rod bushing.
Bushing inside diameter: 24.008 - 24.017 mm (0.9452 - 0.9455 inch)
2. Using a micrometer, measure the piston pin diameter.
Piston pin diameter: 24.000 - 24.009 mm (0.9449 - 0.9452 inch)
3. Subtract the piston pin diameter measurement from the bushing inside diameter measurement.
Standard oil clearance: 0.005 - 0.011 mm (0.0002 - 0.0004 inch)
Maximum oil clearance: 0.015 mm (0.0006 inch)
If the oil clearance is greater than maximum, replace the bushing. If necessary, replace the piston and piston pin as a set.
