Start By:a. remove engine and transmissionb. remove oil pumpc. remove crankshaft rear seal 1. Fasten the engine to tool (A) at the flywheel end as shown.2. Remove bridge (1) and the seals. 3. Remove rear main bearing cap (2). Be sure the location is marked on the main bearing cap before it is removed. The stamped location number is toward the camshaft. 4. Remove upper bearing half (3) with an approved bearing removal tool.
Do not turn the crankshaft in a counterclockwise direction because the tab of the bearing can be pushed between the crankshaft and the engine block. This will cause damage to the crankshaft and engine block.
5. Turn the crankshaft clockwise, as seen from the flywheel, to remove bearing upper half (3). 6. Remove bearing lower half (4) from rear main bearing cap (2). 7. Put the bearing upper half (3) in position on the crankshaft, and use the removal tool to rotate the bearing into position. Turn the crankshaft in a counterclockwise direction to engage bearing tab with the engine block. 8. Install the bearing lower half in the main bearing cap.9. Put a piece of Plastigage (5) across the crankshaft main bearing face. Install main bearings dry when the clearance checks are made. Put clean engine oil on the main bearings for final assembly.10. Put the main bearing cap in position. Put clean engine oil on the threads of the main bearing cap bolts, and tighten them finger tight.11. Tighten the main bearing cap bolts to a torque of 245 N m (180 lb.ft.).12. Remove the bearing cap, and measure the thickness of the Plastigage to determine the bearing clearance. See Engine Specifications for the correct bearing clearance.13. Remove the bearing upper half.14. Put clean engine oil on the bearing upper half, and install it.15. Put clean engine oil on the bearing lower half, and install the main bearing cap.16. Tighten the main bearing cap bolts to a torque of 245 N m (180 lb.ft.).17.

Remove the center main bearing cap, and remove thrust washer (6) from each side of the center main bearing location in the cylinder block.19. Remove the thrust washers from each side of the main bearing cap.20. Repeat Steps 4 through 12 to determine the center main bearing clearance. 21. Install new thrust washers (6) on each side of the center main bearing location in the engine block. Be sure the bearing surface is toward the crankshaft, and the smooth surface is toward the engine block.22. Put clean engine oil on the thrust washers. 23. Put new thrust washers (6) on the side of the main bearing cap. Be sure the tabs on the thrust washers are engaged with the grooves in the main bearing cap.24. Install the center main bearing cap and thrust washer. Be careful the thrust washers do not come out of position.25. Tighten the main bearing cap bolts to a torque of 245 N m (180 lb.ft.).26. Measure the crankshaft end play. See Engine Specifications for the correct end play dimension.27. Install bridge and seals on the cylinder block.End By:a. install crankshaft rear sealb. install oil pumpc. install engine and transmission
