1. Check each connecting rod cap for its location on the crankshaft. Each cap must have a number (1) which is the same as the number on the connecting rod. Do not mix bearings.2. 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.
5. Install the upper bearings in the connecting rods. Slowly pull the connecting rods on the crankshaft. Install the connecting rod bearings dry when the clearance checks are made. Put clean engine oil on the connecting rod bearings for final assembly.6. Install the lower bearings in the connecting rod caps. Be sure tab (3) on the back of the bearing fits in the groove of the caps and connecting rods.
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. Check the bearing clearance with Plastigage as follows:a) Put clean oil on the threads of bolts (4). Install caps (5), Plastigage (A) and the nuts finger tight.b) Tighten each nut (6) to a torque of 80 8 N m (60 6 lb.ft.). c) Put a mark across the nuts and bolts. Tighten the nuts 120° more. Do not use an impact wrench.d) Remove caps (5). Make sure the connecting rod bearing caps are installed with their identification number in alignment with the connecting rod number.8. The clearance for new bearings must be 0.071 to 0.168 mm (.0028 to .0066 in.). The maximum clearance for used bearings is 0.35 mm (0.010 in.).9. Carefully move connecting rod up enough to permit clean engine oil to be put on the upper bearing and crankshaft journal.10. Pull the connecting rod on to the crankshaft.11. Put clean engine oil on the cap bearing.12. Install caps (5). Tighten nuts (6) to a torque of 80 8 N m (60 6 lb.ft.). Tighten the nuts 120° more.END BY:a) install oil pump
