Connecting Rod Final Assembly Procedure

  1. Guide the connecting rod away from the crankshaft connecting rod journal in order to lubricate the crankshaft connecting rod bearing journal.
  2. Apply a liberal amount of crankshaft prelube or clean engine oil to the crankshaft connecting rod bearing journal. Refer to Adhesives, Fluids, Lubricants, and Sealers for recommended lubricant.
  3. Guide the connecting rod to the crankshaft connecting rod journal.
  4. Install the connecting rod end cap on its original connecting rod and ensure the bearing lock tangs are aligned on the same side of the rod.

    CAUTION:

    Do not lubricate the NEW connecting rod bolts. The NEW bolts have a pre-applied graphite lubricant. Applying lubricant to the connecting rod bolts will effect the clamp load when the connecting rod bolts are torqued. Improper clamp load can lead to component failure and extensive engine damage.

    CAUTION:

    This vehicle is equipped with torque-to-yield or single use fasteners. Install a NEW torque-to-yield or single use fastener when installing this component. Failure to replace the torque-to-yield or single use fastener could cause damage to the vehicle or component.

  6. Install the NEW connecting rod bolts into the connecting rod cap.
  7. Tighten the connecting rod bolts.
    1. First Pass

      Tighten the connecting rod bolts to 25 N.m (18 lb ft).

    2. Final Pass

      Tighten the connecting rod bolts an additional 110 degrees using the EN 45059  meter.

  8. During and after installation, ensure each piston is positioned properly in the correct cylinder. The arrow on the top of each piston must be pointing toward the front of the engine.
  9. Repeat these procedures for the remaining piston/connecting rod assemblies using the EN 45059  meter in order to rotate the crankshaft.
