Piston to Piston Pin Oil Clearance

(Piston to piston pin oil clearance) = (Piston pin hole diameter) - (Piston pin outer diameter)

Standard: 0.002 - 0.006 mm (0.0001 - 0.0002 in)

If the calculated value is out of the standard, replace piston and piston pin assembly.
When replacing piston and piston pin assembly, refer to [HOW TO SELECT PISTON AND BEARING ].

NOTE:

Piston is available together with piston pin as assembly.
Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts, no piston pin grades can be selected. (Only "0" grade is available.)
