1996 CHRYSLER VOYAGER oil filter

Install new gasket and tighten screws to 12 N´m (105
in. lbs.).
OIL FILTER
CAUTION: When servicing the oil filter (Fig. 71)
avoid deforming the filter can by installing the
remove/install tool band strap against the can-to-
base lock seam. The lock seam joining the can to
the base is reinforced by the base plate.
(1) Using Tool C-4065, turn filter counterclockwise
to remove from base. Properly discard filter.
(2) Wipe base clean, then inspect gasket contact
surface.
(3) Lubricate gasket of new filter with clean
engine oil.
(4) Install new filter until gasket contacts base.
Tighten filter 1 turn or 20 N´m (15 ft. lbs.). Use filter
wrench if necessary.
(5) Start engine and check for leaks.
ENGINE OIL GALLERY PLUGS
REMOVAL
Using a blunt tool such as a drift and a hammer,
strike the bottom edge of the cup plug. With the cup
plug rotated, grasp firmly with pliers or other suit-
able tool and remove plug (Fig. 72).CAUTION: Do not drive cup plug into the casting
as restricted cooling can result and cause serious
engine problems.
INSTALLATION
Thoroughly clean inside of cup plug hole in cylin-
der block or head. Be sure to remove old sealer.
Lightly coat inside of cup plug hole with Loctite Stud
N' Bearing Mount or equivalent. Make certain the
new plug is cleaned of all oil or grease. Using proper
drive plug, drive plug into hole so that the sharp
edge of the plug is at least 0.5 mm (0.020 in.) inside
the lead-in chamfer.
DISASSEMBLY AND ASSEMBLY

REMOVAL AND INSTALLATION (Continued)

NOTE: When installing seal, no lube on seal is
needed.
(1) Place Special Tool 6926-1 on crankshaft. This is
a pilot tool with a magnetic base (Fig. 60).
(2) Position seal over pilot tool. Make sure you can
read the wordsTHIS SIDE OUTon seal (Fig. 60).
Pilot tool should remain on crankshaft during instal-
lation of seal. Ensure that the lip of the seal is facing
towards the crankcase during installation.
CAUTION: If the seal is driven into the block past
flush, this may cause an oil leak.
(3) Drive the seal into the block using Special Tool
6926-2 and handle C-4171 (Fig. 61) until the tool bot-
toms out against the block (Fig. 62).
CRANKSHAFT
REMOVAL
(1) Remove oil filter and adapter from bedplate.(2) Remove collar from oil pan to transmission
housing.
(3) Remove oil pan.
(4) Remove crankshaft sprocket and oil pump both
procedures outlined in this section.
(5) Remove all main bearing cap and bedplate
bolts from the engine block (Fig. 63).
(6) Using a mallet tap the bedplate loose from the
engine block dowel pins.
