Crankshaft - Installation
INSTALLATION
Special Tools:
1. If required, select and fit new crankshaft main bearings to the engine block Procedures
2. If required, select and fit new bearings to the connecting rod Procedures
3. If removed, install the target wheel (1) to the crankshaft with four new bolts (2). Ensure the threaded holes in the crankshaft are free of residual thread lock adhesive. Tighten the bolts to 10 Nm (89 in. lbs.).
NOTE: Typical V6 engine configuration shown.
4. If removed, lubricate and install the upper main bearing halves (6) into the engine block (7).
CAUTION: When installing the crankshaft, use care not to damage bearing surfaces on the crankshaft.
5. Install the crankshaft (4) into the engine block (7).
NOTE: Typical V6 engine configuration shown.
6. Installing thrust washers (1) at the No. 2 main bearing location, using the following procedure:
a. Move the crankshaft forward to the limit of travel. Lubricate and install the front thrust washer (1) by rolling the washer onto the machined shelf between the No. 2 upper main bulk head and crankshaft thrust surface.
b. Move the crankshaft rearward to the 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.
CAUTION: The main bearing cap 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 main bearing cap 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.
NOTE: Typical V6 engine configuration shown.
8. If removed, lubricate and install the lower main bearing halves (3) onto the main caps (1).
9. Install the main bearing caps (1) with two inner main bearing cap bolts (2).
10. Tighten the inner main bearing cap bolts in the sequence shown to 20 Nm (15 ft. lbs.) plus 90°.
11. Measure crankshaft end play Procedures
NOTE: Typical V6 engine configuration shown.
12. If removed, install the bearing shell (8) on the connecting rod with the tang inserted into the machined groove in the rod. Lubricate the bearing surface with clean engine oil.
CAUTION: Care must be taken not to nick crankshaft journals, as engine damage may occur.
13. Remove the plastic guide plates (3) from the Guide Pins (7) and install the Guide Pins to the connecting rod.
CAUTION: Avoid contact with the piston oil cooler jet(s). Positioning of the oil cooler jet(s) is critical for proper engine operation.
14. Pull the connecting rod and piston toward the crankshaft until the connecting rod is seated on the crankshaft journal. Remove the guide pins.
CAUTION: The connecting rod bolts must not be reused. Always replace the connecting rod bolts whenever they are loosened or removed.
15. If removed, install the bearing shell (6) on the connecting rod cap (4) 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).
16. Install the connecting rod cap and bearing with the tang on the same side as the rod. Tighten the the NEW connecting rod cap bolts (5) to 20 Nm (15 ft. lbs.) plus 90°.
17. If required, check the connecting rod side clearance Measuring Connecting Rod Side Clearance
18. Repeat the previous steps for the remaining connecting rods.
19. Install the windage tray (1) with eight main bearing cap bolts. Tighten the bolts in the sequence shown to 21 Nm (16 ft. lbs.) plus 90°.
NOTE: Typical V6 engine configuration shown.
20. Install the eight main bearing tie bolts. Tighten the bolts in the sequence shown to 28 Nm (21 ft. lbs.).
21. Install the engine oil pump and oil pump pick-up Engine Oil Pump - Installation
22. Install the rear crankshaft oil seal and flexplate Rear Crankshaft Oil Seal - Installation
23. Install the timing chain and sprockets, engine timing cover, oil pans, spark plugs and cylinder head covers Timing Chain & Sprockets - Installation
24. Install the engine Engine - Installation
25. If removed, install the oil filter and fill the engine crankcase with the proper oil to the correct level Service and Repair
26. Connect the negative battery cable and tighten nut to 5 Nm (45 in. lbs.).
27. Fill the cooling system Service and Repair.
28. 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.
