12. INSTALLATION OF OIL PUMP OIL SEALInstall the oil seal into the oil pump cover, making sure that
its lip is in correct direction.
8. APPLICATION OF SEALANT TO OIL PAN(1) Clean both mating surfaces of oil pan and cylinder block.
(2) Apply sealant into groove of oil pan flange, ~keeping clear of
holes as shown. The width of sealant bead as sqeezed outof tube should be about 4 mm
(.I6 in.).
Caution
After application of sealant, do not exceed l’5 minutes
before installing the oil pan.

2. INSTALLATION OF OIL PRESSURE
SWlTCHCoat the threads of switch with sealant and install the
switch using the special tool.
Specified sealant: MOPAR Part No.4318034 or equiva-
lent
Caution
1. Keep the end of threaded portion clear of sealant.2. Avoid an
overtightening.
1. APPLICATION OF ENGINE OIL TO OIL FILTERApply a thin coat of engine oil to the packing surface.
,.Caution
Do not apply oil too much.

N026:(2) Install the front case assembly through a new front
case gasket and temporarily tighten the flange bolts
(other than those for tightening the filter bracket).
(3) Mount the oil filter bracket with oil filter bracket gasket.
Then, install the four bolts with washers.
(4) Tighten the bolts to specification.
NOTE
Bolts indicated by the * symbol should be tightened at atorque of 27-34 Nm
(20-25 ft.1b.s.).20. INSTALLATION OF DRIVEN GEAR BOLT
(1) Insert a Phillips screwdriver into a hole in the left side ofthe cylinder block to lock the silent shaft.
(2) Secure the oil pump driven gear onto the left silent
shaft by tightening the driven gear bolt to specified
torque.18. INSTALLATION OF PLUG CAP
(1) Install a new O-ring to the groove of front case.
(2) Using the special tool, install the plug cap and tighten tospecified torque.

equivalent
(3) The oil pan should be installed in 15 minutes after the
application of sealant.
(4) Note the difference in bolt lengths at the location
shown.8. INSTALLATION OF OIL PRESSURE SWITCH
(1) Coat sealant on the thread area, and using the special
tool, install the pressure switch.
Specified sealant: MOPAR Part No.4318034

Caution
1. Do not let sealant ooze out of the top of the
thread area.
2. Do not overtighten the pressure switch.
(2) Install the oil pressure switch terminals.
5. INSTALLATION OF OIL COOLER
First insert the oil cooler projecting stopper in the oil filter
bracket groove and then tighten the oil cooler bolts.lu3. INSTALLATION OF OIL FILTER
Wipe clean the mounting surface on the filter bracket.
Then, apply a thin coat of engine oil to filter O-ring and
tighten the oil filter by hand.
Caution
-.Never use a wrench to tighten the oil filter.
