ENGINE 2.0L DOHC
CRANKSHAFT (Continued)
(1) Install the main bearing upper shells with the
lubrication groove and oil hole in the engine block.
Install O-ring into recess in the block (Fig. 46).

1 - LUBRICATION GROOVES
2 - O-RING
3 - OIL HOLES
(2) Make certain oil holes in block line up with oil
hole in bearings and bearing tabs seat in the block
tab slots.
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 bedplate mating
surface. It will affect the sealer ability to seal the
bedplate to cylinder block.
(3) Oil the bearings and journals and install
crankshaft in engine block.
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 the bed plate as
shown in (Fig. 47).
(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. 48).

(8) To ensure correct thrust bearing alignment,
perform the following steps:
• 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. 48) to 41 N·m (30 ft. lbs.).
• Step 6: Remove wedge tool used to hold crankshaft.
(9) Tighten bolts (1–10) again to 41 N·m (30 ft.
lbs.) in sequence shown in (Fig. 48).
(10) Install main bearing bedplate to engine block
bolts (11–20), with baffle studs in positions 12, 13
