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 pressing in
the piston pin (6) and install the snap ring to the groove.
3. Clean the cylinder bore, connecting rod bearing journal,
connecting rod bearing shell and the piston and coat them
with engine oil.
4. Install the piston ring using the tensioning strap(000 589
04 14 00).
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 bearing.
Notice
If the basic bore exceeds the value of 51.614mm, replace
the bearing or check the connecting rod.
2. Check connecting rod bolts.
3. Check the assembly mark(indication//or number:arrow) of
the connecting rods and the bearing cap when installing.
Notice
lMake sure it doesn’t exceed over 4g with other
connecting rods when replacing the connecting rods.
lCheck if the connecting rod and the bearing cap are
accurately seated on the groove when replacing the
bearing. Notice
If the length exceeds max. length, replace it.
