Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
Note: Install the connecting rod bearings dry when the clearance checks are made. Put clean engine oil on the connecting rod bearings for final assembly.
- Install the upper half of the connecting rod bearing in the connecting rod.
- Install the lower half of the connecting rod bearing in the connecting rod.
Note: Align the tabs on the back of the connecting rod bearings with the tab grooves in the connecting rod.
- In order to check the connecting rod bearing clearance, put Tool (A) (Plastigage) on the connecting rod bearing, as shown.

- Remove the connecting rod cap. Measure Tool (A) (Plastigage) on the bearing surface before Tool (A) (Plastigage) is removed. The clearance between the connecting rod bearing and a new crankshaft should be 0.076 to 0.168 mm (.0025 to .0066 inch). The clearance between the connecting rod bearing and a used crankshaft should be 0.25 mm (0.01 inch) .
- Install connecting rod cap (2) and connecting rod nuts (1) on connecting rod (3) . Repeat Step 378 in order to tighten the nuts.
- Repeat Steps 1 through 8 for the remaining connecting rod bearings.
End By: Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
