    NOTE:

    There are no timing marks on the oil pump gear or chain. Timing of the oil pump is not required.

    CAUTION:

    Always reinstall timing chains so that they maintain the same direction of rotation. Inverting a previously run chain on a previously run sprocket will result in excessive wear to both the chain and sprocket.

  5. Place the oil pump sprocket (4) into the oil pump chain (3). Align the oil pump sprocket with the oil pump shaft and install the sprocket. Install the T45 retaining bolt (2) and tighten the bolts to the proper specifications. Refer to TORQUE SPECIFICATIONS .
  6. Remove the retaining pin (1). Verify that the oil pump chain is centered on the tensioner and crankshaft sprocket.
  7. Rotate the crankshaft clockwise one complete revolution to verify proper oil pump chain installation.
