5-13. CONNECTING ROD ASSEMBLY MAINTENANCE INSTRUCTIONS - Continued
If inspection reveals the presence of scoring
on the bearing surfaces, replace the connect-
ing rod bearing halves (8).
The presence of scoring on the connecting
rod bearing (8) inner surfaces, requires
that the crankshaft bearing journal be in-
spected (Para. 5-20).
Inspect the connecting rod (7) and the cap (6) for
cracks or other damage. Replace connecting rod
and cap if damaged in any way.
Inspect the inner surface of the rod bushing in-
stalled in the connecting rod (7). Repair the con-
necting rod if bushing is scored.
Inspect threaded fasteners for stripped threads or
other damage. Replace any fasteners found de-
Inspect cover (2) for damage that would hinder its
ability to provide a tight seal. Replace a damaged
If connecting rod bearing halves (8) are be-

Replace rod bushing as follows:
Using an arbor press with a pressing sleeve
(25 mm O.D. x 75 mm L, with 22 mm pilot
shoulder on one end), press the bushing from
the connecting rod.
Ensure that the bore of connecting rod and re-
placement bushing are clean.
Align replacement bushing with rod bore, en-
suring that the oil hole in the bushing is in line
with the oil passage in top of the connecting
rod. Using an arbor press with pressing
sleeve, install the bushing to be flush with
face of connecting rod.
edge of the bearing halves and the marks
on connecting rod and cap. Reinstalled
bearings must be installed in the same lo-
cation they were removed from.
Install one connecting rod bearing half (8) in con-
necting rod (7), by first aligning the lip of the bear-
ing half with groove in connecting rod. Slide the
bearing half into the rod while depressing the cen-
ter of the bearing to conform it to the contour of
the rod. Seat the bearing with both ends flush
with flanges of the rod.
Install second connecting rod bearing half (8) in
the connecting rod cap (6) in a similar manner.
A number is stamped on one side of the
connecting rod (7) and the connecting rod
cap (6). It is important that these numbers
be on the same side when installing the
connecting rod and cap.
