CRANKSHAFT (Continued)
CAUTION: Use only the specified anaerobic sealer
on the bedplate or damage may occur to the
engine.
(4) Apply a 1.5 to 2.0 mm (0.059 to 0.078 in.) bead
of Mopar Bed Plate Sealant to cylinder block as
shown in (Fig. 59).
Fig. 59 Bedplate Sealing
(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 oil threads 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 (Fig. 60).

Sequence
(8) To ensure correct thrust bearing alignment,
perform the following steps:
ENGINE 2.0L DOHC
• Step 1: Rotate crankshaft until number 4 piston
is at TDC.
• Step 2: Move crankshaft rearward to limits of
travel.
• Step 3: Then, move crankshaft forward to limits
of travel.
• Step 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.
• Step 5: Install and tighten bolts (1–10) in
sequence shown in (Fig. 67) to 41 N·m (30 ft. lbs.).
• Step 6: Remove wedge tool used to hold crank-
shaft.
(9) Tighten bolts (1–10) again to 41 N·m (30 ft.
lbs.) in sequence shown in (Fig. 60).
(10) Install main bearing bedplate to engine block
bolts (11–20), with baffle studs in positions 12, 13
and 16 and torque each bolt to 34 N·m (25 ft. lbs.) in
sequence shown in (Fig. 60).
(11) Tighten bolts (1–10) to 81 N·m (60 ft. lbs.) in
sequence shown in (Fig. 60).
(12) Tighten bolts (11–20) again to 34 N·m (25 ft.
lbs.) in sequence shown in (Fig. 60).
(13) After the main bearing bedplate is installed,
check the crankshaft turning torque. The turning
torque should not exceed 5.6 N·m (50 in. lbs.).
(14) Check crankshaft end play (Refer to 9 -
ENGINE/ENGINE BLOCK/CRANKSHAFT - STAN-
DARD PROCEDURE).
NOTE: The connecting rod cap bolts should not be
reused.
(15) Before installing NEW bolts, lubricate the
threads with clean engine oil.
(16) Install each bolt finger tight then alternately
torque each bolt to assemble the cap properly.
(17) Tighten the connecting rod bolts using the 2
step torque-turn method. Tighten according to the
following values:
CAUTION: Do not use a torque wrench for the sec-
ond step.
1. Tighten the bolts to 27 N·m (20 ft. lbs.).
2. Tighten the connecting rod bolts an additional
1/4 TURN.
(18) Install oil pump (Refer to 9 - ENGINE/LU-
BRICATION/OIL PUMP - INSTALLATION).
(19) Install oil pump pick-up tube. Torque fastener
to 23 N·m (200 in. lbs.).
(20) Install the oil pan (Refer to 9 - ENGINE/LU-
BRICATION/OIL PAN - INSTALLATION).
(21) Install oil filter adapter and oil filter (Fig. 53)
(Refer to 9 - ENGINE/LUBRICATION/OIL FILTER
ADAPTER - INSTALLATION).
