• Piston pin clearance:
Check piston pin clearance in small end and piston. Replace
connecting rod and/or piston if its small end is badly worn or
damaged or if measured clearance exceeds limit.
Piston pin clearance in connecting rod small end
0.003 – 0.014 mm (0.0001 – 0.0006 in.)
Piston pin clearance in piston
0.006 – 0.017 mm (0.00024 – 0.00067 in.)
Small-end bore for connecting rod
20.003 – 20.011 mm (0.7875 – 0.7878 in.)
Piston pin diameter
19.997 – 20.000 mm (0.7873 – 0.7874 in.)
Piston bore
20.006 – 20.014 mm (0.7876 – 0.7880 in.)
Piston Rings
To measure end gap, insert piston ring (1) into cylinder bore and
then measure the gap by using thickness gauge (2).
If measured gap is out of specification, replace ring.
NOTE:
Decarbon and clean top of cylinder bore before inserting
piston ring.

Connecting Rod
• Big-end side clearance:
Check big-end of connecting rod for side clearance, with rod
fitted and connected to its crank pin in the normal manner. If
measured clearance is found to exceed its limit, replace con-
necting rod.
