clean engine oil before installation.
(2) While holding camshaft sprocket and chain in
hand, place timing chain around the sprocket, align-
ing the plated link with the dot on the sprocket. Posi-
tion the timing arrow to the 6 o'clock position (Fig.
140).

perpendicular on nose of crankshaft (Fig. 1).
(2) Move crankshaft all the way to the rear of its
travel.
(3) Zero the dial indicator.
(4) Move crankshaft all the way to the front and
read the dial indicator. Refer to Engine Specifica-
tions.
REMOVAL - CRANKSHAFT
NOTE: Crankshaft can not be removed when engine
is in vehicle.
(1) Remove engine assembly from vehicle (Refer to
9 - ENGINE - REMOVAL).
(2) Separate transaxle from engine.
(3) Remove drive plate/flex plate.
(4) Remove crankshaft rear oil seal (Refer to 9 -
ENGINE/ENGINE BLOCK/CRANKSHAFT OIL
SEAL - REAR - REMOVAL).
(5) Mount engine on a suitable repair stand.
(6) Drain engine oil and remove oil filter.
(7) Remove crankshaft vibration damper (Refer to
9 - ENGINE/ENGINE BLOCK/VIBRATION
DAMPER - REMOVAL).
(8) Remove engine mount support bracket.
(9) Remove front timing belt covers (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT COVER(S)
- REMOVAL).
(10) Remove the timing belt (Refer to 9 - ENGINE/
VALVE TIMING/TIMING BELT AND SPROCKETS -
REMOVAL).(11) Remove the rear timing belt cover (Refer to 9
- ENGINE/VALVE TIMING/TIMING BELT COV-
ER(S) - REMOVAL).

SHAFT - REMOVAL).
(16) Remove crankshaft position sensor.
NOTE: If piston/connecting rod replacement is nec-
essary, remove cylinder head (Refer to 9 - ENGINE/
CYLINDER HEAD - REMOVAL).
(17) Using a permanent ink or paint marker, iden-
tify cylinder number on each connecting rod cap (Fig.
2).
CAUTION: DO NOT use a number stamp or a punch
to mark connecting rods. Damage to connecting
rod could occur.
(18) Remove all connecting rod bolts and caps.
Care should be taken not to damage the fracture rod
and cap surfaces.
NOTE: Do not reuse connecting rod bolts.
(19) Remove all bed plate bolts from the engine
block (Fig. 3).
(20) Using a mallet gently tap the bed plate 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.
(21) Bed plate should be removed evenly from the
cylinder block dowel pins to prevent damage to the
dowel pins and thrust bearing.

9s - 6 ENGINE 2.4L SUPPLEMENTRS

CAUTION: Use extreme care when handling crank-
shaft. Tone wheel damage can occur if crankshaft is
mis-handled.
(22) Lift out crankshaft from cylinder block. Do
not damage the main bearings or journals when
removing the crankshaft.
(23) Remove the target ring mounting screws and
discard.
(24) Remove the target ring from the crankshaft.
INSPECTION
For crankshaft specifications (Refer to 9 - ENGINE
- SPECIFICATIONS).
The crankshaft journals should be checked for
excessive wear, taper and scoring (Fig. 4). Limits of
taper or out of round on any crankshaft journals
should be held to 0.025 mm (0.001 in.). Journal
grinding should not exceed 0.305 mm (0.012 in.)
under the standard journal diameter. DO NOT grind
thrust faces of No. 3 main bearing. DO NOT nick
crank pin or bearing fillets. After grinding, remove
rough edges from crankshaft oil holes and clean out
all passages.
CAUTION: With the nodular cast iron crankshafts, it
is important that the final paper or cloth polish be
in the same direction as normal rotation in the
engine.
INSTALLATION - CRANKSHAFT
CRANKSHAFT MAIN BEARING LOCATION
The crankshaft is supported in five main bearings.
All upper bearing shells in the crankcase have oil
grooves and holes. All lower bearing shellsexcept
for the thrust bearing half have oil grooves and holes
(Fig. 5). Crankshaft end play is controlled by a
flanged bearing on the number three main bearing
journal.

RSENGINE 2.4L SUPPLEMENT9s-7
CRANKSHAFT (Continued)

(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.

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
