Installation Procedure
1. Check the piston ring gap and apply the engine oil to
the piston pin and the connecting rod bushing.
2. Connect the piston and the connecting rod by press-
ing in the piston pin (6) and install the snap ring to the
groove.
3. Clean the cylinder bore, connecting rod bearing jour-
nal, connecting rod bearing shell and the piston and
coat them with engine oil.
4. Install the piston ring.
5. Install the piston so that the arrow on the piston head
faces to the forward of the vehicle.
6. After aligning the connecting rod and the bearing cap
mark (// or a number), tighten the bolts.

Inspection
1. Measure the basic bore of the connecting rod bear-
ing.
Notice:If the basic bore exceeds the value of
51.614mm, replace the bearing or check the connecting
rod.
2. Check connecting rod bolts.
