4. Calculate:
8piston-pin-to-piston-pin-bore clearance
Out of specification J Replace the pis-
ton pin and piston as a set.
Piston-pin-to-piston-pin-bore clearance =
Piston pin bore diameter b -
Piston pin outside diameter a
Piston-pin-to-piston clearance
0.002 ~ 0.018mm (0.00008 ~
0.0007in)
3. Measure:
8piston pin bore diameter b
Out of specificationJ Replace the piston.
Piston pin bore diameter
15.002 ~ 15.013mm (0.5906 ~
0.5911in)
<Limit>:15.043mm (0.5922in)
2. Measure:
8piston pin outside diameter a
Out of specification J Replace the pis-
ton pin.
Piston pin outside diameter
14.995 ~ 15.000mm (0.5904
~0.5906in)
<Limit>:14.975mm (0.5896in)
