2004 CHRYSLER VOYAGER engine

(1) Install the main bearing upper shells with the
lubrication groove and oil hole in the engine block
(Fig. 6).
(2) Make certain oil holes in block line up with oil
hole in bearings and bearing tabs seat in the block
tab slots.
NOTE: If the crankshaft is sent out for machine
work, it must be balenced as an assembly with the
target ring installed.
(3) Clean crankshaft and target ring with
MOPARtbrake parts cleaner and dry with com-
pressed air to ensure that the crankshaft mating sur-
face and target ring mounting holes are free from oil
and lock patch debris.
NOTE: Always use NEW mounting screws whether
installing original or new target ring.
(4) InstallNEWmounting screws finger tight
starting with the #1 location. (Fig. 7) Make sure
engagment occurs with the shoulder of the screw and
mounting hole before starting all other screws.
(5) Torque all mounting screws with T30 torx bit
to 13 Nm (110 in-lbs) following the torque sequence.
CAUTION: Use extreme care when handling crank-
shaft. Tone wheel damage can occur if crankshaft is
mis-handled.
CAUTION: Do not get oil on the bed plate mating
surface. It will affect the ability of the sealer to seal
the bed plate to cylinder block.(6) Oil the bearings and journals. Install crank-
shaft in the engine block.
CAUTION: Use only MoparTBed Plate Sealant on
the bed plate or damage may occur to the engine.
(7) Install lower main bearings into main bearing
cap/bed plate. Make certain the bearing tabs are
seated into the bed plate slots and apply oil.
(8) Apply 1.5 to 2.0 mm (0.059 to 0.078 in.) bead of
MopartBed Plate Sealant to bed plate as shown in
(Fig. 8).

(9) Install the main bearing/bed plate into engine
block.
(10) Before installing the bolts the threads should
be oiled with clean engine oil, wipe off any excess oil.
(11) Install main bearing bed plate to engine
block bolts 11, 17, and 20 finger tight. Tighten these
bolts down together until the bed plate contacts the
cylinder block.
(12) To ensure correct thrust bearing alignment,
perform the following steps:
²Step 1: Rotate crankshaft until number 4 piston
is at TDC.
²Step 2: Move crankshaft rearward to limits of
travel.
²Step 3: Then, move crankshaft forward to limits
of travel.
²Step 4: Wedge an appropriate tool between the
rear of the cylinder block(NOT BED PLATE)and
the rear crankshaft counterweight. This will hold the
crankshaft in it's furthest forward position.
²Step 5: Install and tighten bolts (1±10) in
sequence shown in (Fig. 9) to 41 N´m (30 ft. lbs.).
²Step 6: Remove wedge tool used to hold crank-
shaft.
(13) Tighten bolts (1±10) again to 41 N´m (30 ft.
lbs.) in sequence shown in (Fig. 9).
CAUTION: Do Not use a torque wrench for the fol-
lowing step.
(14) Turn bolts (1±10) an additional 1/4 turn in
sequence shown in (Fig. 9).(15) Install main bearing bed plate to engine
block bolts (11±20), and torque each bolt to 28 N´m
(250 in. lbs.) in sequence shown in. (Fig. 9)
(16) Tighten bolts (11±20) again to 28 N´m (250 in.
lbs.) in sequence shown in (Fig. 9).
(17) After the main bearing bed plate is installed,
check the crankshaft turning torque. The turning
torque should not exceed 5.6 N´m (50 in. lbs.).
(18) Check crankshaft end play (Refer to 9 -
ENGINE/ENGINE BLOCK/CRANKSHAFT - STAN-
DARD PROCEDURE).
(19) Install connecting rod bearings and caps.Do
Not Reuse Connecting Rod Bolts.Torque connect-
ing rod bolts to 27 N´m (20 ft. lbs.) plus 1/4 turn.
(20) Install balance shafts and housing assembly
(Refer to 9 - ENGINE/VALVE TIMING/BALANCE
SHAFT - INSTALLATION).
(21) Install the oil pump (Refer to 9 - ENGINE/
LUBRICATION/OIL PUMP - INSTALLATION).
(22) Install oil pump pick-up tube. Torque fastener
to 28 N´m (20 ft.. lbs.).
(23) Install the oil pan (Refer to 9 - ENGINE/LU-
BRICATION/OIL PAN - INSTALLATION).
(24) Install crankshaft position sensor.
(25) Install cylinder head if it was removed (Refer
to 9 - ENGINE/CYLINDER HEAD - INSTALLA-
TION).
(26) Install the timing belt rear cover (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT COVER(S)
- INSTALLATION).
(27) Install crankshaft sprocket (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT AND
SPROCKETS - INSTALLATION).
(28) Install the timing belt (Refer to 9 - ENGINE/
VALVE TIMING/TIMING BELT AND SPROCKETS -
INSTALLATION).
(29) Install the timing belt front covers (Refer to 9
- ENGINE/VALVE TIMING/TIMING BELT COV-
ER(S) - INSTALLATION).
(30) Install engine mount support bracket.
(31) InstallNEWoil filter.
(32) Install crankshaft rear oil seal (Refer to 9 -
ENGINE/ENGINE BLOCK/CRANKSHAFT OIL
SEAL - REAR - INSTALLATION).
(33) Install flex plate. Apply MopartLock & Seal
Adhesive to bolt threads and tighten to 95 N´m (70
ft. lbs.).
(34) Attach transaxle to engine. Tighten attaching
bolts to 101 N´m (75 ft. lbs.).
(35) Install the engine assembly (Refer to 9 -
ENGINE - INSTALLATION).
