Crankshaft - Installation

INSTALLATION






CAUTION: Main bearings are select fit Procedures for proper bearing size selection.

1. Install crankshaft upper main bearings in cylinder block. Ensure oil holes in bearings line up with oil holes in cylinder block Procedures.
2. Install the crankshaft to cylinder block.










3. Move crankshaft forward to limit of travel. Lubricate and install the front thrust washer by rolling the washer onto the machined shelf between the No. 2 upper main bulk head and crankshaft thrust surface.
4. Move crankshaft rearward to limit of travel. Lubricate and install the rear thrust washer by rolling the washer onto the machined shelf between the No. 2 upper main bulk head and crankshaft thrust surface.





5. Install lower main bearings (3) into main bearing caps (1).
6. Lubricate lower main bearings (3) with clean engine oil.

NOTE: Lubricate main bearing cap inner bolts (2) with engine oil before installation.

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





8. Verify that the #2 main bearing cap is properly centered over the inner bolt holes located in the block using steps 9 thru 14.
9. Tighten main bearing cap inner bolts to 20 Nm (15 ft. lbs.).
10. Move crankshaft (1) forward to limit of travel so that crankshaft thrust face (2) is tight against thrust bearing.





11. Verify that a 0.25 mm (0.010 inch) shim or feeler gage will fit between the #2 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 #2 main journal.





12. Move crankshaft (1) rearward to limit of travel so that crankshaft thrust face (2) is tight against thrust bearing.
13. Verify that a 0.25 mm (0.010 inch) shim or feeler gage will fit between the #2 main cap (front face) and the crankshaft thrust face similar to step 11. 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 #2 main journal.
14. A properly centered #2 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 #2 main bearing cap until this minimum clearance can be verified by repeating steps 8 thru 14.

CAUTION: The #2 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.





15. Following verification of proper #2 bearing cap centering, finish tightening the main bearing cap inner bolts an additional 90° turn.
16. Measure crankshaft end play Procedures.





17. 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, lastly the main cap tie (horizontal) bolts.

18. Install windage tray (3). Lubricate bolts with engine oil. Finger tighten all bolts first, then tighten to 28 Nm + 90° turn (20 ft. lbs. + 90° turn) beginning with the inside bolts tightening outward.
19. Install oil pickup tube (1) and tighten bolt to 28 Nm (20 ft. lbs.).





20. Install the main cap tie (horizontal) bolts and tighten to 28 Nm (20 ft. lbs.).










21. Install rear crankshaft oil seal retainer and oil seal Crankshaft Rear Oil Seal Retainer - Installation.
22. Install oil pump assembly Removal and Replacement
23. Install dowel pin in crankshaft .
24. Install the crankshaft sprocket, timing belt and tensioner Timing Belt & Sprockets - Installation.
25. Install front timing belt cover Engine Timing Cover(s) - Installation.
26. Install oil pan Engine Oil Pan - Installation.
27. Install engine assembly Engine - Installation.
28. Fill engine crankcase with proper amount of oil.
