Repair Procedure:

This repair involves replacing the crankshaft, main bearings, rod bearings, and rear seal retainer.

Use the appropriate Service Manual as a guide in performing the following steps.

1. Remove the engine.

2. Remove the oil pan and timing chain cover.

3. Remove the old crankshaft.

NOTE: BE SURE TO MARK THE MAIN BEARING AND ROD BEARING CAPS TO INSURE CORRECT ASSEMBLY.

4. Install the upper main and thrust bearing halves in the block.

NOTE: THE UPPER BEARING HALVES HAVE AN OIL SUPPLY HOLE AND GROOVE. THE LOWER BEARING HALVES HAVE NO OIL SUPPLY HOLE OR GROOVE. THE THRUST BEARING LOCK TAB IS LOCATED ONLY ON THE LOWER BEARING HALF.

5. Install the new crankshaft.

6. Install the lower main and thrust bearing halves in the bearing caps.

7. Install the main bearing caps and finger tighten the bolts.

8. Install the connecting rod bearings and caps, tighten the rod nuts to 54 N-m PLUS 1/4 TURN (40 ft.lbs. PLUS 1/4 turn) torque.

9. Tighten number 1, 3, and 4 main bearing cap bolts to 41 N-m PLUS 1/4 turn (30 ft. lbs. PLUS 1/4 turn) torque.
10. Rotate the crankshaft so that number 6 piston is at or near top dead center.

11. To ensure correct alignment of the thrust bearing halves the following procedure MUST BE FOLLOWED:

^ Using a leather or rubber mallet, sharply strike the front of the crankshaft at the vibration damper bolt hole (this will drive the crankshaft to its rear most position)

^ Now, sharply strike the rear of the crankshaft (this will drive crankshaft to its foremost position).

Figure 3:

^ Wedge a pry bar or screwdriver between the rear of the block and the rear crankshaft counterweight to hold the crankshaft in its foremost position. Figure 3.

^ Tighten the thrust bearing cap bolts to 41 N-m PLUS 1/4 turn (30 ft.lbs. PLUS 1/4 turn) torque. Remove the pry bar.

^ Check crankshaft end play.
12. Install the timing chain cover.

13. Install crankshaft rear oil seal retainer and gasket. Tighten bolts to 12 N-m (105 inch lbs.) torque.

NOTE: BE SURE TO USE SEAL PILOT TOOL C-4681 WHEN INSTALLING OIL SEAL AND RETAINER ASSEMBLY.

Figure 4:

14. Install the oil pan and gasket. Be sure to apply RTV sealer as shown in Figure 4.
15. Apply a light coat of multi-purpose grease PN 4318063 to the inside of the pilot bushing bore at the rear of the crankshaft.

16. Inspect the torque converter pilot at the front of the converter for nick or burrs. Remove any nicks or burrs with an oil stone or fine tooth file.

17. Install the engine.


NOTE: BE SURE TO INSTALL NEW SPACERS PN 5252229 ON THE CRANKSHAFT AND CAMSHAFT REFERENCE SENSORS.
