2
Inspect rod bushing for scoring, overheating, or other damage. Replace if damaged.
3
Measure outside diameter of rod bushing. Measurement should be 1.1042 to 1.1037 inches
(28.048 to 28.035 mm). If measurement is outside specified limits, replace rod bushing.
4
Measure inside diameter of connecting rod bushing bore. Measurement should be 1.1028 to 1.1024
inches (28.013 to 28.000 mm). If measurement is outside specified limits, replace connecting rod.
Be certain that the numbers on both halves of the con-
necting rod match.
NOTE
Clean rust preventive from replacement connecting rod. Also
make sure bearing bore is thoroughly cleaned to prevent
trapped contaminants from adversely affecting bearings.
5
If required, clamp connecting rod in a padded vise and install new rod bushing (9) into connecting
rod bushing bore.
INSTALLATION:
Be certain that bearing halves are installed correctly. The
bottom bearing half (8) has a hole which fits into lower con-
necting rod half (6).
1
Carefully insert bearing halves (8) into connecting rod.
Be certain that the numbers on both halves of the connecting
rod match.
When installing connecting rod, make sure it does not knock
against crankcase. This could result in serious damage to
connecting rod.
2
Install top half of connecting rod (7) on crankshaft.
3
Install bottom half of connecting rod (6) (with dipper opening to dipstick side) and Allen screws
(5). Using a torque wrench and Allen socket, tighten screws to 29.50 foot-pounds (40 N·m).
