  6. Installing thrust washers (1) at the No. 2 main bearing location, using the following procedure:
    1. Move the crankshaft forward to the limit of travel. Lubricate and install the rear thrust washer (1) by rolling the washer onto the machined shelf between the No. 2 upper main bulk head and crankshaft thrust surface.
    2. Move the crankshaft rearward to the 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.

    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.

  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.
  13. Remove the plastic guide plates (3) from the Guide Pins (special tool #8189, Guide Pins) (7) and install the Guide Pins to the connecting rod.
    CAUTION:

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

  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 NEW  connecting rod cap bolts (5) to the proper torque specification. Refer to TECHNICAL SPECIFICATIONS .
  17. If required, check the connecting rod side clearance. Refer to ROD, PISTON AND CONNECTING, STANDARD PROCEDURE .
  18. Repeat the previous steps for the remaining connecting rods.

  20. Install the eight main bearing tie bolts. Tighten the bolts in the sequence shown to the proper torque specification. Refer to TECHNICAL SPECIFICATIONS .
  21. Install the engine oil pump and oil pump pick-up. Refer to PUMP, ENGINE OIL, REMOVAL AND INSTALLATION .
  22. Install the rear crankshaft oil seal and flexplate. Refer to SEAL, CRANKSHAFT OIL, REAR, REMOVAL AND INSTALLATION .
  23. Install the timing chain and sprockets, engine timing cover, oil pans, spark plugs and cylinder head covers. Refer to CHAIN AND SPROCKETS, TIMING, REMOVAL AND INSTALLATION .
  24. Install the engine. Refer to REMOVAL AND INSTALLATION .
  25. If removed, install the oil filter and fill the engine crankcase with the proper oil to the correct level. Refer to OIL, STANDARD PROCEDURE .
  26. Operate the engine until it reaches normal operating temperature. Check cooling system for correct fluid level.
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.
