a. remove oil pump
1. Check each connecting rod cap for its location on the crankshaft. Each cap (1) must have a number which is the same as the number on the connecting rod. Do not mix bearings.
2. Use tool (A) to turn the crankshaft until two of the pistons are at bottom center.
3. Remove connecting rod caps (2). Remove the lower bearing from the connecting rod caps.
4. Push the connecting rods away from the crankshaft and remove the upper bearings from the connecting rods.

|---|
Be careful not to damage the crankshaft journals. Do not turn the crankshaft while any of the connecting rod caps are removed. |
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.
5. Install the upper half of the rod bearings in the connecting rod.
6. Install the lower half of the rod bearing in the connecting rod cap. Make sure Plastigage (4) is in position on the lower bearing.
NOTE: Be sure tab (3) on the back of the bearings fits in the groove of the caps and connecting rods.
NOTE: When connecting rod caps are installed, make sure the number on the side of the cap is next to, and respective with, the number on the side of the connecting rod.
7. Put clean engine oil on bolt threads. Put caps (2) in position on the connecting rods and install the nuts. Tighten the nuts with the procedure that follows:
a) Tighten each nut to a torque of 81 ± 8 N·m (60 ± 6 lb ft).
b) Put a mark across the nuts and bolts. Tighten the nuts 120 degrees (1/3 turn) more.
| NOTICE |
|---|
Do not use an impact wrench to tighten the nuts the additional 120 degrees. |
8. Remove the cap and measure the Plastigage. The rod bearing clearance for new bearings must be 0.071 to 0.168 mm (.0028 to .0066 in). The maximum clearance for used bearings is 0.25 mm (.010 in).
9. Put bearing cap (2) in position, and tighten the bolts as in Step 7.
10. Repeat Steps 1 through 9 for the other connecting rod bearings.
