ton oil ring groove. Then force the ring into oil ring
groove with the thumb as shown.
• Ensure the ring can turn from the left to the right
freely after installation.

Inspection
Bearing Radial Clearance
•Check the radial clearance of connecting rod bearing.
CONNECTING ROD RADIAL CLEARANCE
Radial Clearance 0.016 - 0.051 mm
Bearing Oil Clearance (Plastigauge)
•Check the oil clearance of the connecting rods and crankshaft.
Clean all engine oil off of the connecting rod bearing and the crankshaft journal.
Cut the plastigauge into lengths as wide as the crankshaft journal.
Lay the plastigauge across the crankshaft
journal.
Carefully install the connecting rod cap.
Torque the connecting rod cap nuts to 20 N·m
Carefully disassemble the connecting rod cap.
Use the measuring rule imprinted on the plas- tigauge package to measure the width of the
widest part of the plastigauge.

Assembly
NOTE :
•The connecting rod bolts should NOT be reused.
• Before installing the NEW rod bolts, apply clean engine oil to the threads and under the bolt heads.
Piston and Connecting Rod
•Oil the piston rings and the side of the piston.
• Position the piston rings in the proper alignment
with the piston pin (2):
Top Ring (1)
Bottom Ring (3)
Oil Control Ring (4)
• Install protective coverings over the connecting rod
bolts.
• Rotate the crankshaft journal to the lowest position.
• Use a suitable piston ring compressor to insert the
piston and connecting rod assembly into cylinder.
• Make sure the forward mark on the top of the pis-
ton is facing the front of the engine (5).
• Using a suitable tool, tap the piston and connecting rod assembly into cylinder.
NOTE :
The piston direction mark (2) should point toward the
timing belt side (1).
• Check the axial clearance of the connecting rods.

Connecting Rod Bearings
•Perform the following steps when replacing the connecting rod bearings:
Measure and record the External Diameter of
the connecting rod journals.
Use the connecting rod bearing identification table to locate the desired bearing.
• The bearing will have an identification mark (1) imprinted in the position as shown.

3 White 44.980 - 44.985 3 Blue 1.495 - 1.499
NOTE :
As an example, if the measurement of the external diameter of the connecting rod journal is 44.996 mm, it will be
identified as Group 1 in the table. If the crankshaft has been replaced, check the identification color applied to the
new crankshaft journal. If the journal is yellow, the crankshaft bearing will be from Group 1, and the connecting rod
bearing will be identified as 1.

•Apply engine oil to the connecting rod bolts.
• Install each connecting rod nut finger tight, then
alternately tighten each nut to assemble the cap
properly.
• Tighten the connecting rod nuts using the two step
torque-turn method:
1st Step: Tighten nuts to 20 N·m
2nd Step: Tighten the connecting rod nuts an
additional 90°- 100°
CAUTION:
If the nuts are over tightened (exceed angle of
100°), loosen the nuts and restart the torque
sequence from Step 1.
