Measurement of the connecting rod-the clearance of
the connecting rod bush 0.050-0.125mm. The axial
clearance 0.15-0.35mm. The clearance between
smaller end bush and piston pin 0.04-0.06.mm.
Measurement of piston pin, the piston pin is of
cylinder-shaped structure with uniform thickness
and the diameter is 52mm.If the clearance measured
is beyond the range when maintaining.
