Piston: Specifications
PISTON PIN OIL CLEARANCE
Using a caliper gauge, measure the inside diameter of the piston pin hole.
Piston Pin Hole Inside Diameter
Using a micrometer, measure the piston pin diameter.
Piston Pin Diameter
Subtract the piston pin diameter measurement from the piston pin hole diameter measurement.
Standard oil clearance ....................................................................................................................... 0.002 to 0.004 mm (-0.00004 to 0.00002 inch)
Maximum oil clearance ......................................................................................................................................................... 0.015 mm (0.0006 inch)
If the oil clearance is greater than the maximum, replace the piston and piston pin as a set.
Using a caliper gauge, measure the inside diameter of the connecting rod bushing.
