ASSEMBLY
The piston. connecting rod and
related parts are shown in Fig. 35. Check
the fit of a new piston in the cylinder
bore
before assembling the piston
and piston
pin to the connecting rod.
The piston pin bore of a connecting
rod and the diameter of the
piston
p_
i n
must
be
within specifications.
Refer
specifications.
1. Apply a light coat of engine
oil
to
all parts. Assemble the
piston to the
connecting rod with the cylinder number
side of the connecting rod and the arrow
on the piston positioned as shown in Fig.
36. On replacement connecting rods,
install the large-chamfered side
of
the
connecting rod bearing bore towards the
crankshaft cheek
;
facing towards front
of
engine on right bank rods, and facing
towards rear of engine on left
bank
rods.
2. Start the piston pin in the
piston
and connecting rod (this may require a
very light tap with a mallet). Using an
Arbor Press and the tool shown in Fig. 34,
press the piston pin through the
piston
and connecting rod until the
pin
·is
centered in the piston.
3. Check the end gap of all piston
rings (page 8-18 ).
It
must be within
specifications.
Follow the instructions
contained on the piston ring package
and
install the piston rings.
4. Check the ring side clearance
of
the compression rings with a feeler gauge
inserted between the ring and its lower
land.
The gauge should slide freely around
the entire ring circumfere1:1ce without
binding.
Any wear that occurs will forrn a
step at the inner portion of the lower
land.
If
the lower lands have high steps,
the
piston should be replaced.
5.
Be sure the bearing inserts and the
bearing bore in the connecting rod and cap
are clean. Foreign material
under the
inserts will distort the bearing and cause a
failure.
Install the bearing inserts in
the
connecting rod and cap with tangs fitting
in the slots provided.
