(6) Lower vehicle and remove upper timing belt
cover fasteners and remove cover.
(7) Remove right engine mount and support
bracket. Refer to Removal and Installation procedure
in this section.
CAUTION: When aligning crankshaft and camshaft
timing marks always rotate engine from crankshaft.
Camshaft should not be rotated after timing belt is
removed. Damage to valve components may occur.
Always align timing marks before removing timing
belt.
(8) Before the removal of the timing belt, rotate
crankshaft until TDC mark on oil pump housing
aligns with TDC mark on crankshaft sprocket (trail-
ing edge of sprocket tooth) (Fig. 58).
NOTE: The crankshaft sprocket mark is located on
the trailing edge of the sprocket tooth. Failure to
align trailing edge of sprocket tooth to mark on oil
pump housing will cause the camshaft marks to be
misaligned (Fig. 58).
(9) Install 6 mm Allen wrench into belt tensioner.
Before rotating the tensioner insert the long end of a
1/8º or 3 mm Allen wrench into the pin hole on thefront of the tensioner (Fig. 59). While rotating the
tensioner counterclockwise push in lightly on the 1/8º
or 3 mm Allen wrench, until it slides into the locking
hole.
(10) Remove timing belt.

CAUTION: If timing belt was damaged due to incor-
rect tracking (alignment), the belt tensioner assem-
bly must be replace. Refer to Timing Belt Tensioner
Assembly Removal and Installation procedure out-
lined in this section.
INSTALLATION
(1) Set crankshaft sprocket to TDC by aligning
the sprocket with the arrow on the oil pump housing.
(2) Set camshafts timing marks so that the
exhaust camshaft sprocket is a 1/2 notch below the
intake camshaft sprocket (Fig. 61).
CAUTION: Ensure that the arrows on both cam-
shaft sprockets are facing up.
(3) Install timing belt. Starting at the crankshaft,
go around the water pump sprocket, idler pulley,
camshaft sprockets and then around the tensioner
(Fig. 62).
(4) Move the exhaust camshaft sprocket counter-
clockwise (Fig. 62) to align marks and take up belt
slack.
NOTE: A new tensioner is held in the wound posi-
tion by a pull pin.
(5) Remove the pull pin or Allen wrench from the
belt tensioner.
(6) Once timing belt has been installed and ten-
sioner released, rotate crankshaft two (2) complete
revolutions. Verify that the TDC marks on crank-
shaft and timing marks on the camshafts are aligned
as shown in (Fig. 60).
(7) Install right engine mount and support
bracket. Refer to Removal and Installation procedure
in this section.
(8) Install upper timing belt cover bolts 4.5 N´m
(40 in. lbs.).
(9) Install the lower timing belt cover bolts 4.5
N´m (40 in. lbs.).
(10) Install crankshaft damper. Refer to procedure
outlined in this section.
(11) Install accessory drive belts. Refer to Group 7,
Cooling System.

INSTALLATION
CAUTION: If burr or scratch is present on the
crankshaft edge (chamfer), cleanup with 400 grit
sand paper to prevent seal damage during installa-
tion of new seal.
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. 76).
(2) Position seal over pilot tool. Make sure you can
read the wordsTHIS SIDE OUTon seal (Fig. 76).
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. 77) until the tool bot-
toms out against the block (Fig. 78).

CRANKSHAFT
REMOVAL
NOTE: Crankshaft can not be removed when
engine is in vehicle.
(1) Remove oil filter and oil pan. Refer to proce-
dure outlined in this section.
(2) Remove Timing Belt Cover, Timing Belt and
Oil Pump. Refer to procedure outlined in this section.
(3) Remove Balance Shafts Assembly. Refer to pro-
cedure outlined in this section.
(4) Remove all main bearing cap bedplate bolts
from the engine block. Refer to procedure outlined in
this section.
(5) Using a mallet gently tap the bedplate loose
from the engine block dowel pins.
CAUTION: Do not pry up on one side of the bed-
plate. Damage may occur to cylinder block to bed-
plate alignment and thrust bearing.
(6) Bedplate should be removed evenly from the
cylinder block dowel pins to prevent damage to the
dowel pins and thrust bearing.
(7) Lift out crankshaft from cylinder block. Do not
damage the main bearings or journals when remov-
ing the crankshaft.
INSTALLATION
(1) Install the main bearing shells with the lubri-
cation groove in the cylinder block (Fig. 82).
(2) Make certain oil holes in block line up with oil
hole in bearings and bearing tabs seat in the block
tab slots.CAUTION: Do not get oil on the bedplate mating
surface. It will may effect the sealer ability to seal
the bedplate to cylinder block.
(3) Oil the bearings and journals. Install crank-
shaft.
CAUTION: Use only the specified anaerobic sealer
on the bedplate or damage may occur to the
engine.
(4) Apply 1.5 to 2.0 mm (0.059 to 0.078 in.) bead of
Mopar Torque Cure Gasket Maker to cylinder block
as shown in (Fig. 83).
(5) Install lower main bearings into main bearing
cap/bedplate. Make certain the bearing tabs are
seated into the bedplate slots. Install the main bear-
ing/bedplate into engine block.
(6) Before installing the bolts the threads should
be oiled with clean engine oil, wipe off any excess oil.

(7) Install main bearing bedplate to engine block
bolts 11, 17 and 20 finger tight. Tighten these bolts
down together until the bedplate contacts the cylin-
der block.
(8) To ensure correct thrust bearing alignment per-
form the following steps:
²Step 1: Rotate crankshaft until number 4 pis-
ton is at TDC.
²Step 2: Move crankshaft rearward to limits of
travel.
²Step 3: Then, move crankshaft forward to lim-
its of travel.
²Step 4: Wedge an appropraite 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. 84) to 41 Nzm (30 ft. lbs.).
²Step 6: Remove wedge tool used to hold crank-
shaft.
(9) Tighten bolts (1-10) again to 41 Nzm (30 ft. lbs)
+ 1/4 turn in sequence shown in (Fig. 84).
(10) Install main bearing bedplate to engine block
bolts (11-20), and torque each bolt to 28 Nzm (20 ft.
lbs.) in sequence shown in (Fig. 84).
(11) After the main bearing bedplate is installed,
check the crankshaft turning torque. The turning
torque should not exceed 5.6 Nzm (50 in. lbs.).
OIL FILTER
CAUTION: When servicing the oil filter avoid
deforming the filter can by installing the remove/in-
stall 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) Turn counterclockwise to remove.
(2) To install, lubricate new filter gasket. Check
filter mounting surface. The surface must be smooth,
flat and free of debris or old pieces of rubber. Screw
filter on until the gasket contacts base. Tighten to 21
N´m (15 ft. lbs.).

PISTON AND CONNECTING ROD
REMOVAL
NOTE: Cylinder Head must be removed before Pis-
tons and Rods. Refer to Cylinder Head Removal in
this section.
(1) Remove top ridge of cylinder bores with a reli-
able ridge reamer before removing pistons from cyl-inder block.Be sure to keep tops of pistons
covered during this operation. Mark piston with
matching cylinder number (Fig. 90).
(2) Remove oil pan. Scribe the cylinder number on
the side of the rod and cap (Fig. 91) for identification.
(3) Pistons have a directional stamping in the
front half of the piston facing towards thefrontof
engine.
(4) Pistons and connecting rods must be removed
from top of cylinder block. Rotate crankshaft so that
each connecting rod is centered in cylinder bore.
