(2) Install the pump (Fig. 116). Verify the idler
gear pin is installed in the locating bore in the cylin-
der block. Tighten the oil pump mounting bolts in
two steps, in the sequence shown in (Fig. 122).
• Step 1—Tighten to 8 N·m (71 in. lbs.) torque.
• Step 2—Tighten to 24 N·m (18 ft. lbs.) torque.

(3) The back plate on the pump seats against the
bottom of the bore in the cylinder block. When the
pump is correctly installed, the flange on the pump
will not touch the cylinder block.
(4) Measure the idler gear to pump drive gear
backlash and the idler gear to crankshaft gear back-
lash (Fig. 123). The backlash should be 0.15- 0.25
mm (0.006-0.010 inch). If the backlash is out of lim-
its, replace the oil pump.
(5) If the adjoining gear moves when you measure
the backlash, the reading will be incorrect.

(6) Apply a bead of Mopar Silicone Rubber Adhe-
sive Sealant or equivalent to the gear housing cover
sealing surface.
(7) Install the gear housing cover (Refer to 9 -
ENGINE/VALVE TIMING/GEAR HOUSING COVER
- INSTALLATION).
(8) Install the vibration damper (Refer to 9 -
ENGINE/ENGINE BLOCK/VIBRATION DAMPER -
INSTALLATION) and speed indicator ring.
(9) Install the fan support/hub assembly and
torque bolts to 32 N·m (24 ft. lbs.).
(10) Install hydraulic pump.
(11) Install accessory drive belt tensioner. Torque
bolt to 43 N·m (32 ft. lbs.).
(12) Install the accessory drive belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
INSTALLATION).
(13) Install the cooling fan (Refer to 7 - COOLING/
ENGINE/RADIATOR FAN - INSTALLATION).
(14) Connect battery negative cables.
(15) Start engine and check for oil leaks.
