Piston, Engine

Piston oil clearance





Using a micrometer, measure the piston diameter at right angles to the piston pin center line, 28.0 mm (1.102 inch) from the piston head.
Piston diameter 78.925 - 78.935 mm (3.1073 - 3.1077 inch)
Subtract the piston diameter measurement from the cylinder bore diameter measurement.
Standard oil clearance 0.065 - 0.088 mm (0.0026 - 0.0035 inch)
Maximum oil clearance 0.10 mm (0.0039 inch)

Piston Pin Oil Clearance





Using a caliper gauge, measure the inside diameter of the connecting rod bushing.
Bushing inside diameter 20.012 - 20.021 mm (0.7879 - 0.7882 inch)





Piston pin diameter 20.004 - 20.013 mm (0.7876 - 0.7879 inch)
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)
