12. Measure the bearing oil clearance.
• Install the bearing to the connecting rod big
end.
• Tighten the bearing cap to the two step o
f
angular tightening method.
• Use an inside dial indicator to measure the
connecting rod bearing inside diameter.
Connecting rod bearing cap bolt torque:
N ⋅m (kg ⋅m / lb ft)
1st step 29.4 (3.0 / 22)
2nd step 45 deg
If the clearance between the measured bearing
inside diameter and the crankpin exceeds the
specified limit, the bearing and/or the crankshaft
must be replaced.
Crankpin and bearing clearance mm (in)
Standard 0.029 - 0.083 (0.0011 - 0.0033)
Limit 0.10 (0.0039)
Reassembly
1. Install the piston.
2. Install the connecting rod. • Install it so that the front mark of the head o
f
the piston, and the connecting rod forging mark
(projecting) on the connecting rod, both face in
the same direction.
• Install the snap ring of one side.

4. Apply enough engine oil on the piston pin, push it
in the piston and the connecting rod small edge.
5. Use snap ring pliers to install the snap ring.
Note:
Make sure that the snap ring is installed in the ring
groove properly. Make sure that the connecting rod
moves smoothly.

Installation
1. Install the connecting rod bearing.
• Install the bearing on the connecting rod, and
apply engine oil on the bearing.
2. Install the piston and connecting rod assembly. • Apply enough engine oil on the piston ring, ring
groove and piston side surface.
• W ith the piston front mark cut facing forward,
use the piston ring compressor to insert the
piston in the cylinder block.
Note: • Be sure not to make the connecting rod touch
the oil jet when pushing in the piston.
• Be sure not to harm the inside of the cylinde
r
block when pushing in the piston.
