REPAIR INSTRUCTIONS, PART 1
Page 161
It is essential that the cap and rod be kept
together when removed from the engine and
when installed. Each rod and cap is marked with
matching numbers to identify them as a set. At
assembly, the numbers must appear side by side
and the notches must be aligned. Refer to
Figure 207. Tag the sets on removal so each set
can be returned to the cylinder from which it was
removed.
Do not install a damaged connecting rod
assembly. Failure to heed this caution may result
in severe component damage.
Do NOT use a pneumatic impact wrench to
tighten connecting rod screws. It will damage the
mating surfaces. Failure to heed this caution may
result in severe component damage.
WRIST PIN REMOVAL
1. Using snap ring pliers, remove the retainers
at each end of the wrist pin.
2. Remove the wrist pin from the piston and
connecting rod.
INSPECTION
208
Figure 208 — Piston Assembly — Exploded View
Connecting rods fall into weight classes. When
installing a single rod, or less than a full set,
examine the removed rods for a part number.
Install parts having the same weight class.
Connecting rods can be weighed to be certain
that the proper weight class is used. Rod weights
for an engine should not vary by more than
13.04 grams (0.46 ounce) within each weight
class.
Inspect each connecting rod and cap for the
following conditions. If any fault appears, replace
both rod and cap.
1. Inspect the connecting rods for nicks,
cracks, signs of overheating and
unacceptable bending and twisting.
2. Inspect the bolt holes for elongation and
damaged threads.
