Piston and Piston Pin - Clearance

PISTON AND PISTON PIN CLEARANCE






1. Measure inner diameter of piston pin hole "dp".

Standard diameter"dp": 20.969 - 20.981 mm (0.8255 - 0.8260 inch)






2. Measure outer diameter of piston pin "Dp".

Standard diameter"Dp": 20.971 - 20.983 mm (0.8256 - 0.8261 inch)

3. Calculate piston pin clearance.

dp - Dp = 0 to -0.004 mm (0 to -0.0002 inch)

If it exceeds the above value, replace piston assembly with pin.
