start by:a) remove oil pan plateb) remove oil pump1. Turn the crankshaft until two pistons are at bottom center. Remove connecting rod caps (1) from the two connecting rods. Remove the lower half of the bearings from the caps.2. Push the connecting rods away from the crankshaft and remove the upper half of the bearings.3. Clean the surfaces where the bearings fit. Install the upper half of the new bearings in the rods. Put the connecting rods in position on the crankshaft.4. Clean the surfaces where the bearings fit. Install the lower half of the new bearings in the caps.
When the connecting rods 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.
5. Check the bearing clearance with plastigage (A). Put caps (1) in position on the connecting rods and install the nuts. Tighten the nuts to a torque of 30 3 lb.ft. (40 4 N m). Put a mark on each nut and the end of each bolt. Tighten the nuts 90° more.6. Remove the cap. Measure the thickness of the Plastigage. The rod bearing clearance (Plastigage thickness) must be .0030 to .0066 in. (0.076 to 0.168 mm) with new bearings. The maximum permissible clearance is .010 in. (0.25 mm) with used bearings.7. Put clean engine oil on the bearings, crankshaft journals, bolt threads and contact surfaces of the nuts.8. Put the caps in position on the connecting rods and install the nuts. Tighten the nuts to a torque of 30 3 lb.ft. (40 4 N m). Put a mark on each nut and the end of each bolt. Tighten the nuts 90° more.9. Do Steps 1 through 7 again for the other bearings.end by:a) install oil pumpb) install oil pan plate
