PISTON PIN
Piston Pin Diameter
Use a micrometer to measure the piston pin outside
diameter at several points.
If the measured value is less than the specified limit, the
piston pin must be replaced.
Piston Pin Diameter mm(in)
Standard Limit
31.0 (1.220) 30.97 (1.219)
Piston Pin and Piston Clearance
Use an inside dial indicator to measure the piston pin
hole (in the piston).
Piston Pin Hole mm(in)
Standard
29.002 – 29.007
Piston Pin and Piston Pin Hole
Clearance mm(in)
0.002 – 0.015 (0.00008 – 0.0006)
Piston Pin and Connecting Rod Small End Bushing
Clearance
Use a caliper calibrator and a dial indicator to measure
the piston pin and connecting rod small end bushing
clearance.
If the clearance between the piston pin and the connect-
ing rod small end bushing exceeds the specified limit,
replace the piston pin and/or the connecting rod
bushing.
Piston Pin and Connecting Rod Small
End Bushing Clearance mm(in)
Standard Limit
0.008 – 0.020 0.05
(0.0003 – 0.0008) (0.002)
