Pump, Engine Oil: Removal: Removal

When removing and installing the Balance Shaft/Oil Pump assembly in the vehicle, it is not necessary to align the plated links on the drive chain as long as the reference marks are created during the procedure. 

1. Remove the oil pan

   Refer to PAN, OIL, REMOVAL .

2. Rotate the engine clockwise until the balance shaft/oil pump drive gear and the housing indicator are aligned.
   NOTE:

   IT IS VERY IMPORTANT THAT THE CRANKSHAFT STAYS STATIONARY DURING THE FOLLOWING STEPS. DO NOT MOVE THE CRANKSHAFT UNTIL THE INSTALLATION PROCEDURE IS COMPLETED. 

3. Clean the balance shaft/oil pump assembly drive gear with Mopar® brake cleaner or similar.
   NOTE:

   Make sure the gear is clear of any oil to allow for marking.

5. Install one air-conditioning compressor bracket bolt into the left forward corner thread boss.
   NOTE:

   The bolt will provide a sturdy point to secure a tie strap to hold the tensioner in the compressed position.
