Pump, Engine Oil: Removal
Do not remove the bolt for the sprocket as this is a non-serviceable part and the bolt is a one-time use fastener. If the bolt is removed, the entire balance shaft assembly will have to be replaced.
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.
- Remove the oil pan. Refer to REMOVAL
.
- Remove the screws (1) and remove the splash shield.
- Rotate the crankshaft clockwise until the balance shaft/oil pump drive gear indicator (1) and the housing indicator (2) 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.
- 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.
- If the balance shaft/oil pump assembly is being reused, mark the oil pump chain and the sprocket (1) to the module body (2) for reassembly.
- 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.
- Position a plastic tie strap (3) around the chain, tensioner (4) and bolt (2) that was previously installed.
- Push the chain, guide (4) and tensioner (1) to the compressed position.
- Tighten the tie strap (3) to hold the components together.NOTE:
The tighter the strap, the more room for removal and installation of the balance shaft/oil pump assembly.
- Remove the balance shaft/oil pump assembly mounting bolts.
- Remove the assembly from the engine by tilting the rear of the balance shaft/oil pump assembly downward while lifting the drive gear out of the chain links.
- If removal of the tensioner (3) or guides (1, 6) is required, remove the engine timing cover. Refer to REMOVAL .
- If removal of the chain or sprockets is required, remove the engine timing cover, timing chain and crankshaft sprocket. Refer to CHAIN AND SPROCKETS, TIMING, REMOVAL .
