(3) Oil the bearings and journals. Install crank-
shaft 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 cylinder block as
shown in (Fig. 66).
(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 (Fig. 67).
(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. 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. 67).
(10) Install main bearing bedplate to engine block
bolts (11–20), and torque each bolt to 28 N·m (250 in.
lbs.) in sequence shown in (Fig. 67).
