Connecting Rod

CONNECTING ROD





1. Measure the connecting rod large end side clearance.

Clearance: 0.110-0.262 mm (0.0044-0.0103 in)
Maximum: 0.3 mm (0.0118 in)

2. If the clearance exceeds the maximum, replace the connecting rod and cap assembly.





3. Measure the connecting rod large end oil clearances as follows.
1) Position plastigauge atop the crankshaft in the axial direction.
2) Install the connecting rod caps and tighten the connecting rod cap nuts.
3) Remove the connecting rod cap nuts and connecting rod cap.
4) Measure the plastigauge at each crank pin.





Oil clearance:
0.028-0.048 mm (0.0012-0.0018 in) (B6)
0.020-0.044 mm (0.0008-0.0017 in) (BP)
Maximum: 0.10 mm (0.0039 in)

5) If the oil clearance exceeds the maximum, replace the connecting rod bearing or grind the crank pin and use undersize bearings.








4. Measure each connecting rod bushing inner diameter.

Diameter: 20.003-20.014 mm (0.7876-0.7879 in)

5. Calculate the connecting rod bushing-to-piston pin clearance. If the clearance is not as specified, replace the connecting rod or piston pin.

Clearance: 0.010-0.027 mm (0.0004-0.0010 in)





6. Measure each connecting rod for bending. Repair or replace the connecting rod if necessary.

Bending:
0.075 mm (0.0030 in) max./50mm (1.97in)
Distortion:
0.180 mm (0.0071 in) max./50 mm (1.97 in)





Center-to-center distance:
132.85-132.95 mm (5.2304-5.2342 in)

7. If the connecting rod is replaced, the connecting rod cap must also be replaced because they are machined together.
