1996 CHRYSLER VOYAGER Service Manual

THRUST PLATE INSPECTION
Check the thickness (Fig. 40) of the plate at points
a-b-c-d. If the measurement is not between 3.950 -
4.050 it must be changed.
INSTALLATION
(1) Coat the camshaft journals with clean engine
oil and carefully install the camshaft complete with
thrust plate and gear. Tighten the retaining bolts to
24 N´m. Be sure to align the timing marks as shown.(2) Install hydraulic tappets and retaining yokes.
(3) Install cylinder heads.
(4) Push rods, and rocker arm assemblies. In there
original location.
(5) Install valve cover.
(6) Install Timing case cover.
(7) Install Vibration damper.
(8) Reinstall Engine.
CAMSHAFT BEARINGS
This procedure requires that the engine is removed
from the vehicle.
REMOVAL
(1) With engine completely disassembled, drive out
rear cam bearing core hole plug.
(2) Install proper size adapters and horseshoe
washers (part of Camshaft Bearing Remover/Installer
Tool) at back of each bearing shell. Drive out bearing
shells.
INSTALLATION
(1) Install new camshaft bearings with Camshaft
Bearing Remover/Installer Tool by sliding the new
camshaft bearing shell over proper adapter.
(2) Position rear bearing in the tool. Install horse-
shoe lock and by reversing removal procedure, care-
fully drive bearing shell into place.
(3) Install remaining bearings in the same man-
ner. Bearings must be carefully aligned to bring oil
holes into full register with oil passages from the
main bearing. If the camshaft bearing shell oil holes
are not in exact alignment, remove and install them
correctly. Install a new core hole plug at the rear of
camshaft.Be sure this plug does not leak.
CRANKSHAFT MAIN BEARINGS
REMOVAL
(1) Disconnect battery cable.
(2) Remove engine from vehicle, refer to engine
removal in this section.
(3) Install engine to engine stand.
(4) Remove accessary drive system.
(5) Remove cylinder head cover, refer to cylinder
head cover removal in this section.
(6) Remove rocker arm and push rods, refer to
rocker arm and push rod section in this section.
(7) Remove intake, exhaust manifold and turbo-
charger, refer to Group 11, Exhaust System and
Intake Manifold.
(8) Remove water manifold.
(9) Remove oil feed lines to rocker arms.
(10) Remove cylinder heads.
(11) Remove oil pan and oil pick-up.
(12) Remove piston and connecting rods from
crankshaft journals.

REMOVAL AND INSTALLATION (Continued)

(13) Remove pistons and connecting rods from
block.
(14) Remove vibration damper. Refer to procedure
in this section.
(15) Remove front cover. Refer to procedure in this
section.
(16) Remove oil pump drive gear.
(17) Install special tool VM-1004 onto crankshaft
over gear (Fig. 41).
(18) Remove main bearing oil feed and carrier
locators from block.
(19) Remove flywheel and adaptor plate from
engine block.
(20) Remove thrust bearings from rear main bear-
ing carrier (Fig. 42).
(21) Slide crankshaft and bearing carriers rear-
ward to rear of block. If you encounter difficulty in
removing the complete assembly as previously
described, slide the assembly rearward sufficiently to
gain access to the main bearing carrier bolts. Mark
the carriers for assembly and remove the bolts, two
for each carrier (Fig. 43).
(22) Separate the two halves of each carrier,
remove from the crankshaft and temporarily re-as-
semble the carriers (Fig. 44). Withdraw the crank-
shaft through the rear of the crankcase.
INSTALLATION
NOTE: Assemble engine according to sequence
described, thus saving time and preventing dam-
ages to engine components. Clean parts with a suit-
able solvent and dry them with compressed airbefore assembly. Use new gaskets where applicable
and torque wrenches for correct tightening of com-
ponents.
(1) Thoroughly clean crankcase and oil passages,
and blow dry with compressed air.
(2) Install new main bearing shells in each of the
carrier halves. Assemble the carriers to the crank-
shaft journals, ensuring that the carriers are
installed in their original locations. Secure each car-
rier with the two bolts tightening evenly to 42 N´m
(31 ft. lbs.) (Fig. 44).
(3) Slide special tool (VM-1002) over the crank-
shaft gear and, insert the crankshaft and carrier
assembly into the crankcase in the same manner
used for removal.
(4) Align the holes in the lower carriers, with the
center of the crankcase webs (Fig. 45).
(5) Secure each carrier assembly to the crankcase
with the main bearing oil feed and carrier locators
and tighten them to 54 N´m (40 ft. lbs).
(6) Install rear main bearing carrier onto crank-
shaft ensuring arrow on bearing carrier aligns with
vertical web in center of crankcase.
(7) Install rear oil seal.
(8) Install new O-rings in adaptor plate.
(9) Install adaptor plate and tighten bolts to 47
N´m (35 ft. lbs.).
(10) Install bolts to main bearing carrier and
tighten to 26.5 N´m (20 ft. lbs.).
(11) Position flywheel and O-ring on crankshaft
and align bolt holes.
NOTE: For purposes of checking crankshaft end
play used flywheel bolts may be used. Final assem-
bly requires new flywheel bolts.
(12) Install 2 flywheel bolts, 180É apart, and
tighten bolts to 20 N´m plus 60É (15 ft. lbs.) plus 60É.
(13) Attach dial indicator to engine block.
(14) Move crankshaft toward front of engine and
zero indicator.
(15) Move crankshaft toward the rear of engine
and record measurement.
(16) Subtract specified crankshaft end play from
figure obtained. Crankshaft end play 0.08 to 0.21 mm
(0.0032 to 0.0083 in.).
(17) Select thrust washers which will give correct
end play.
(18) Remove tools and flywheel.
(19) Lubricate thrust washer halves and fit them
into the rear main bearing carrier.
(20) To verify correct end play, install 2 flywheel
bolts 180É apart, and tighten bolts to 20 N´m plus 60É
(15 ft. lbs. plus 60É).
(21) Measure crankshaft end play with a dial
gauge. Crankshaft end play should not exceed 0.08-

REMOVAL AND INSTALLATION (Continued)

0.21 mm (0.0032 to 0.0083 in.) (Fig. 46). If end clear-
ance exceeds these values install oversize thrust
washer.
CAUTION: Use NEW flywheel bolt for the following
procedure.
(22) Install new O-ring on flywheel. Install fly-
wheel. The 6 flywheel bolts must be tightened as fol-
lows:
a. Torque the 6 flywheel bolts to 60 N´m (44 ft.
lbs.).
b. Loosen 2 of the 6 bolts, 180É apart. Torque the 2
bolts to 20 N´m (180 in. lbs.). Then using a torque
angle gauge rotate the 2 bolts 65É additional.
c. Loosen the next 2 bolts, 180É apart and follow
the same procedure.d. Loosen the last 2 bolts, 180É apart and follow
the same procedure.
(23) Install Transmission. Refer to procedure in
Group 21, Transmission.
(24) Install pistons and connecting rod assemblies,
refer to piston and connecting rods in this section.
(25) Install oil pick up tube and tighten bolts to 25
N´m (18 ft. lbs.).
(26) Install oil pan, refer to oil pan installation in
this section.
(27) Install vacuum pump. Tighten retaining
screws to 20 N´m (15 ft. lbs.).
