Crankshaft - Installation

INSTALLATION






NOTE: Upper and lower bearing halves are NOT interchangeable.

CAUTION: Main bearings are select fit Service and Repair .

1. Install crankshaft upper main bearings in cylinder block. Ensure the tangs engage the slots in the block and oil holes in bearings line up with oil holes in cylinder block Service and Repair.
2. Lubricate upper main bearing halves with engine oil.

CAUTION: When installing crankshaft, use care not to damage bearing surfaces on the crankshaft.

3. Install crankshaft.






NOTE: Make sure that the coated and oil groove side of crankshaft thrust washer faces the crankshaft thrust surface.

4. Push crankshaft forward. Lubricate and install the front thrust washer (1) by rolling the thrust washer onto the machined shelf between the No. 3 upper main bulk head and crankshaft thrust surface.
5. Move crankshaft rearward. Lubricate and install the rear thrust washer by rolling the thrust washer onto the machined shelf between the No. 3 upper main bulk head and crankshaft thrust surface.





6. Install lower main bearings (3) into main bearing caps (2).
7. Lubricate lower main bearings (3) with clean engine oil.

NOTE: Lubricate main bearing cap bolts with engine oil before installation.

8. Install each main cap (2) and tighten inner bolts (1) finger tight. Align the location reference mark scribed on the #3 main bearing cap during disassembly.






CAUTION: The #3 main bearing cap must be centered over the inner bolt holes located on the block. Failure to center the bearing cap can result in contact with the crankshaft counterweights and thrust bearing failure.

9. Verify that the #3 main bearing cap is properly centered over the inner bolt holes located in the block:
- Tighten main bearing cap inner bolts to 20 Nm (15 ft. lbs.).
- Move crankshaft (1) forward to limit of travel so that crankshaft thrust face (2) is tight against thrust bearing.





- Verify that a 0.25 mm (0.010 inch) shim or feeler gage will fit between the #3 main cap (rear face) and the crankshaft thrust face. Slide the gage side-to-side all of the way across the cap making sure that the clearance at all areas exceeds 0.25 mm (0.010 inch). The feeler gage should slide all the way down to the #3 main journal.





- Move crankshaft (1) rearward to limit of travel so that crankshaft thrust face (2) is tight against thrust bearing.
- Verify that a 0.25 mm (0.010 inch) shim or feeler gage will fit between the #3 main cap (front face) and the crankshaft thrust face. Slide the gage side-to-side all of the way across the cap making sure that the clearance at all areas exceeds 0.25 mm (0.010 inch). The feeler gage should slide all the way down to the #3 main journal.
- A properly centered #3 main bearing cap has a minimum of 0.25 mm (0.010 inch) clearance in both the forward and rearward crankshaft positions. If measured clearance is less than 0.25 mm (0.010 inch), loosen and reposition #3 main bearing cap until this minimum clearance can be verified by repeating this procedure.





10. Following verification of proper #3 bearing cap centering, finish tightening the main bearing cap inner bolts an additional 90° turn.
11. Measure crankshaft end play Procedures.





12. Install connecting rods and measure side clearance Service and Repair.






NOTE: The main bearing cap bolts must be tightened in the proper sequence. First the inner main cap bolts, secondly the windage tray bolts, and lastly the main cap tie (horizontal) bolts.

13. Install windage tray (1) with the slots to right side of engine. Lubricate bolts (3) with engine oil and tighten to 27 Nm + 90° Turn (20 ft. lbs. + 90° turn).





14. Install the main cap tie (horizontal) bolts (1) and (2) and tighten to 28 Nm (250 in. lbs.).
15. Install rear crankshaft oil seal retainer and oil seal assemblyRear Crankshaft Oil Seal - Installation.





16. Install oil pump assembly (5) Removal and Replacement
17. Install oil pick-up tube (3) and O-ring (2). Tighten bolts (4) to 28 Nm (250 in. lbs.).
18. Install oil pan gasket, oil pan, and oil filter Engine Oil Pan - Installation.
19. Install crankshaft sprocket Timing Chain & Sprockets - Installation.
20. Install timing chain Timing Chain & Sprockets - Installation.
21. Install timing chain cover Engine Timing Cover(s) - Installation.





22. Install cylinder head covers Cylinder Head Cover(s) - Installation.
23. Install oil dipstick tube.
24. Install engine assembly Engine - Installation.
25. Fill engine crankcase with proper oil to correct level Service and Repair.
26. Fill with coolant Service and Repair.
27. Start engine and check for leaks.
