INSPECTION - CONNECTING ROD
Inspect the connecting rod for damage and wear. The
I-Beam section of the connecting rod cannot have
dents or other damage. Damage to this part can
cause stress risers which will progress to breakage.
Measure the connecting rod pin bore (1). The maxi-
mum diameter is 40.042 mm (1.5765 inch), minimum
diameter is 40.019 mm (1.5756 inch). If out of limits,
replace the connecting rod.
INSTALLATION
1. Lubricate the cylinder bores with clean engine oil.
2. Generously lubricate the rings and piston skirts
with clean engine oil.
3. Orientate the rings on the piston (Refer to 9 -
ENGINE/ENGINE BLOCK/PISTON RINGS - STAN-
DARD PROCEDURE).
4. Compress the rings using a piston ring compressor
tool(1).Ifusingastrap-typeringcompressor,
make sure the inside end of the strap does not
hook on a ring gap and break the ring.
5. Bar the crankshaft so the rod journal for the piston
to be installed is at BDC(Bottom Dead Center).
6. Make sure the front of the piston is oriented prop-
erly according to the marking on the top of the pis-
ton and the connecting rod is oriented properly.
7. Position the piston and rod assemblyinto the cylinder bore with the front of the piston oriented properly accord-
ing to the stamping in the top of the piston. Use care when you install the piston and connecting rod so the
cylinder bore is not damaged. The long side of the connecting rod must be installed on the intake side of the
engine.
8. Push the piston into the bore until the top of the piston is approximately50 mm (2 inch) below the top of the
block. Carefully pull the connecting rod onto the crankshaft journal.
9. Use clean engine oil to lubricate the threads and under the heads of the connecting rod bolts.
