Determining piston pin clearance
 P02 45
P02 62
The piston pin clearance is given by the
difference between the internal diameter of
the small end bush (a) and the piston pin
diameter (b).
Calculation example
Desired: Piston pin clearance
Given: -
Measured: Internal diameter small end bush (a)
(a) = 52.040 mm
Diameter piston pin (b)
(b) = 52.000 mm
Calculation: Dimension (a) - Dimension (b)
52.040 mm - 52.000 mm
Result: = 0.040 mm
