Piston Pin: Testing and Inspection

PISTON PIN OIL CLEARANCE INSPECTION





1. Using a caliper gauge, measure the inside diameter of the connecting rod bushing.
Bushing inside diameter: 22.005 - 22.014 mm (0.8663 - 0.8667 inch)





2. Using a micrometer, measure the piston pin diameter.
Piston pin diameter: 21.997 - 22.006 mm (0.8660 - 0.8664 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: 0.05 mm (0.0020 inch)
If the oil clearance is greater than maximum, replace the bushing. If necessary, replace the piston and piston pin as a set.
