Insert internal measuring device.
Balance the internal measuring device at the given
measuring points and read off the measured value at
the reversal point of the pointer.
42 mm
Note the measured value, dimension (A).
Measuring points see diagram.
The dimension A is required to determine
the piston bolt clearance.

Determining the piston bolt clearance
0,034 - 0,056 mm
The piston bolt clearance is given by the
difference between the internal diameter of
the small end bush (dimension A) and the
piston bolt diameter (dimension B).
Calculation example
Desired: Piston pin clearance
Given:
Measured: (A) = 40.045 mm
Calculation: (B) = 40.006 mm
dimension (A) - dimension (B)
Result: = 0.039 mm
