Crankshaft - Installation






INSTALLATION





CAUTION: Main bearings are select fit.

1. Lubricate upper main bearing halves with clean engine oil.

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

2. Position crankshaft in cylinder block.
3. Install the thrust washers (1).









CAUTION: The bedplate to cylinder block mateing surface must be coated with sealant prior to installation. Failure to do so will cause severe oil leaks.

NOTE: The installation time to install the bedplate after the sealant has been applied is critical.

NOTE: Make sure that the bedplate and cylinder block sealing surfaces are clean and free of oil or other contaminants. Contaminants on the sealing surfaces may cause main bearing distortion and/or oil leaks.

4. Apply a 2.5 mm (0.100 inch) bead of Mopar(R) Gen II Silicone Rubber Adhesive sealant (2) to the cylinder block-to-bedplate mating surface (1) as shown.
5. Coat the crankshaft main bearing journals with clean engine oil and position the bedplate onto the cylinder block.





NOTE: Lubricate the bedplate retaining bolts with clean engine oil prior to installation.

6. Install the bedplate retaining bolts, making sure to place the stud bolts in the correct location, Torque the bolts in the sequence shown.
- Tighten bolts A - L to 54 Nm (40 ft. lbs.)
- Tighten bolts 1-10 to 2.8 Nm (25 in. lbs.)
- Turn bolts 1-10 an additional 90�.
- Tighten bolts A1- A6 to 27 Nm (20 ft. lbs.)

7. Measure crankshaft end play.
8. Install the connecting rods and measure side clearance.




9. Position the oil pan gasket/windage tray, using a new o-ring, install the oil pickup tube. Torque the bolt to 28 Nm (20 ft. lbs.) torque the nuts to 28 Nm (20 ft. lbs.).
10. Install the oil pan. Torque the retaining bolts to 15 Nm (11 ft. lbs.) in the sequence shown.
11. Install the engine.
