4.5 Pistons, Pins, Rings, Connecting Rods
and Big-end Bearings
Remove
1 Remove the engine assembly, refer to 4.1 Engine .
2 Remove both cylinder head assemblies, refer to 3.22 Cylinder Head Assembly.
3 Remove the oil pan assembly, refer to 4.2 Oil Pan and Oil Pump Suction Pipe Assembly .
4 Mark the top of the piston being remo ved to identify its specific bore.
5 Install Tool No. EN-46111 (1) onto the crankshaft (2).

(BDC).


Figure 6A1 – 464
CAUTION
If the connecting rod bearings have been
used in a running engine, they must be
replaced with new connecting rod bearings
for reassembly.
7 Before removing the connecting rods, check the connec ting rod side clearance using the following procedure:
a Tap the connecting rod to one end of the cranks haft journal with a dead blow or wooden hammer.
b Using feeler gauges, measure the clearance between the crankshaft counterweight and the connecting rod.
c The connecting rod side clearance should not exceed specifications, refer to 5 Specifications.
d If the endplay exceeds the specified limits, measure the width of the crankpin end of the connecting rod, refer
to 5 Specifications .
e If the connecting rod width is significantly smaller than specified and severe wear is present on the side of the
connecting rod, replac e the connecting rod.
f If the connecting rod width is within specification and excessive scoring is present on the crankshaft journals,
replace the crankshaft.
CAUTION
Do not use a stamp, punch or any other
method that may distort or stress the
connecting rod and cap. Extensive engine
damage may result from a connecting rod that
is distorted or stressed.
8 Mark the cylinder number on the connec ting rod and the connecting rod cap with a paint stick or permanent marker.
