Installing Piston and Connecting Rod Assembly

CAUTION: To prevent engine damage, do not allow
the connecting rod or connecting rod cap fractured
mating surfaces to contact any surface other then
its matched fractured surface.
other surface can cause misalignment of the mating
surface, resulting in connecting rod bearing and
engine failure.
NOTE: Turn crankshaft so connecting rod journals 1
and 6 are at Bottom Dead Center (BDC). Install piston
and connecting rod assemblies 1 and 6 first. Then
repeat the procedure for piston and connecting rod
assemblies 2 and 5. Finish with piston and connecting
rod assemblies 3 and 4.
1. Install connecting rod bearings into connecting
rods and connecting rod caps dry (without oil).
2. Lubricate piston rings with clean engine oil.
Stagger piston ring gaps approximately 120
degrees from each other.
3. Install the piston ring compression tool (Table 34)
over the piston rings.
4. Lubricate the cylinder sleeve and connecting rod
bearing shell with clean engine oil.
CAUTION: To prevent engine damage, install each
piston with the arrow to the front of the engine and the
CAM SIDE mark toward the cam side of the engine.
CAUTION: To prevent engine damage, make sure
that the longer side of the connecting rod bolted joint
is oriented opposite the camshaft side of the engine.
5. Carefully install the piston and connecting rod
assembly without rod cap into the cylinder sleeve
with the arrow on the piston crown pointing to
the front of the engine. Use a wooden or plastic
handle to carefully push the assembly into the
cylinder sleeve. Do not scratch the cylinder wall.
