Crankshaft - Installation

INSTALLATION





CAUTION: Main bearings are select fit Refer to - ENGINE/ENGINE BLOCK/CRANKSHAFT MAIN BEARINGS - STANDARD PROCEDURE 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. (Refer to - ENGINE/ENGINE BLOCK/CRANKSHAFT MAIN BEARINGS - STANDARD PROCEDURE)
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 into main bearing caps.
6. Lubricate lower main bearings with clean engine oil.

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

7. Install each main cap and tighten bolts finger tight.
8. 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.
9. Install the inside main bearing cap bolts and tighten to 20 Nm + 1/4 turn (15 ft. lbs. + 1/4 turn).
10. Measure crankshaft end play.
11. Install connecting rods and measure side clearance.
12. Install windage tray. 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.
13. Install the main cap tie (horizontal) bolts and tighten to 28 Nm (250 in. lbs.).
14. Install rear crankshaft oil seal retainer and oil seal.
15. Install oil pump assembly.
16. Install dowel pin in crankshaft.
17. Install crankshaft sprocket.
18. Install timing belt and tensioner.
19. Install front timing belt cover.
20. Install oil pickup tube and tighten bolt to 28 Nm (250 in. lbs.).
21. Install oil pan.
22. Install engine assembly.
23. Fill engine crankcase with proper amount of oil.
