Crankshaft - Installation

INSTALLATION

Special Tools:










1. If removed, install the piston oil cooler jet(s) Piston Oil Cooler Jet - Installation.
2. If required, select and fit new crankshaft main bearings to the engine block Procedures.
3. If required, select and fit new bearings to the connecting rod Service and Repair.

NOTE: The upper center main bearing (1) has the thrust washers attached.

4. If removed, lubricate and install the upper main bearing halves (1 and 2) into the engine block.
5. Install two bedplate locating dowels (3).






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

6. Install the crankshaft (1) into the engine block.






CAUTION: The bedplate bolts are tightened using a torque plus angle procedure. The bolts must be examined BEFORE reuse. If the threads are necked down the bolts must be replaced.

7. Check the bedplate bolts for necking by holding a scale or straight edge against the threads. If all the threads do not contact the scale (2) the bolt must be replaced.





8. If removed, lubricate and install the lower main bearing halves (1) into the bedplate.
9. Clean the cylinder block and bedplate mating surfaces with isopropyl alcohol in preparation for sealant application.

CAUTION: Engine assembly requires the use of a unique sealant that is compatible with engine oil. Using a sealant other than Mopar(R) Engine RTV GEN II may result in engine fluid leakage.

CAUTION: Following the application of Mopar(R) Engine RTV GEN II to the gasket surfaces, the components must be assembled within 10 minutes and the attaching fasteners must be tightened to specification within the next 10 minutes. Prolonged exposure to the air prior to assembly may result in engine fluid leakage.

10. Apply a 2 to 3 mm wide bead of Mopar(R) Engine RTV GEN II sealant (2) to the bedplate as shown.





11. Position the bedplate onto the cylinder block. Make sure the bedplate seats fully over the locating dowels.
12. Install the twenty bedplate bolts finger tight.
13. Tighten the bedplate bolts in the sequence shown, following this 5 step torque plus angle method. Tighten according to the following torque values:
- Step 1: 1 through 10 to 20 Nm (15 ft. lbs.).
- Step 2: 11 through 20 to 15 Nm (11 ft. lbs.).
- Step 3: 1 through 10 again to 20 Nm (15 ft. lbs.).
- Step 4: 1 through 10 + 80° Turn Do not use a torque wrench for this step.
- Step 5: 11 through 20 to 32 Nm (27 ft. lbs.).

14. Measure crankshaft end play Procedures.





15. If removed, install the bearing shell on the connecting rod with the tang inserted into the machined groove in the rod. Lubricate the bearing surface with clean engine oil.
16. Install the (10281) (4) on the connecting rod.

CAUTION: Care must be taken not to nick crankshaft journals, as engine damage may occur.

17. Pull the connecting rod and piston toward the crankshaft until the connecting rod is seated on the crankshaft journal. Remove the connecting rod guides.

CAUTION: The connecting rod bolts must not be reused. Always replace the connecting rod bolts whenever they are loosened or removed.

18. If removed, install the bearing shell (3) on the connecting rod cap (1) with the tang inserted into the machined groove in the cap. Lubricate the bearing surface with clean engine oil.

NOTE: Do not lubricate the threads of the connecting rod cap bolts (5).

19. Install the connecting rod cap and bearing with the tang on the same side as the rod. Tighten the NEW connecting rod cap bolts (2) to 20 Nm (15 ft. lbs.) plus 40 degrees.
20. If required, check the connecting rod side clearance Measuring Connecting Rod Side Clearance.
21. Repeat the previous steps for the remaining connecting rods.





22. Install a new oil filter housing oil return tube O-ring seal (1).





23. Install the oil filter housing oil return tube (2) between the bedplate and oil filter housing with two gaskets (4). Tighten the bolt (3) to 9 Nm (80 in. lbs.) and tighten the bolt (1) to 33 Nm (24 ft. lbs.).
24. Install the engine oil pump, timing belt and sprockets Engine Oil Pump - Installation.
25. Install the rear crankshaft oil seal and transmission Rear Crankshaft Oil Seal - Installation.





26. Install the engine Engine - Installation.
27. If removed, install the oil filter and fill the engine crankcase with the proper oil to the correct level Service and Repair.
28. Connect the negative battery cable and tighten nut to 5 Nm (45 in. lbs.).
29. Fill the cooling system Service and Repair.
30. Operate the engine until it reaches normal operating temperature. Check cooling system for correct fluid level Service and Repair.

NOTE: The Cam/Crank Variation Relearn procedure must be performed using the scan tool anytime there has been a repair/replacement made to a powertrain system, for example: flywheel, valvetrain, camshaft and/or crankshaft sensors or components.
