NOTE: Do not reuse connecting rod bolts.
(18) Remove all main bearing cap and bedplate
bolts from the engine block (Fig. 96).
(19) Using a mallet 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 and bed-
plate alignment.
(20) Bedplate should be removed evenly from the
cylinder block dowel pins.
(21) Lift out crankshaft from cylinder block (Fig.
94). Be sure not to damage the main bearings or
journals when removing the crankshaft.
CRANKSHAFT MAIN BEARINGS LOCATION
The crankshaft is supported in five main bearings.
All upper bearing shells in the crankcase have oil
grooves. All lower bearing shells installed in the (bed-
plate) main bearing cap are plain. Crankshaft endplay is controlled by a flanged bearing on the number
three main bearing journal (Fig. 97).
NOTE: The upper and lower main Bearing shells
are Not interchangeable. The lower shells have a
revised tab to prevent improper installation.
CRANKSHAFT MAIN JOURNALS INSPECTION
The crankshaft journals should be checked for
excessive wear, taper and scoring. 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
Number 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
used it is important that the final paper or cloth pol-
ish after any journal regrind be in the same direc-
tion as normal rotation in the engine.
Upper and lower Number 3 bearing halves are
flanged to carry the crankshaft thrust loads and are
NOT interchangeable with any other bearing halves
in the engine (Fig. 97). All bearing cap bolts removed
during service procedures are to be cleaned and oiled
before installation. Bearing shells are available in
standard and the following undersized: 0.016 mm
(0.0006 in.), 0.032 mm (0.0012 in.), 0.250 mm (0.010
in.). Never install an undersize bearing that will
reduce clearance below specifications.

REMOVAL AND INSTALLATION (Continued)

INSTALLATION
(1) Install the main bearing shells with the lubri-
cation groove in the cylinder block. Install O-ring
into recess in the block (Fig. 98).
(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 affect the sealer ability to seal the
bedplate to cylinder block.
(3) Oil the bearings and journals and install
crankshaft in cylinder block.
CAUTION: Use only the specified anaerobic sealer
on the bedplate or damage may occur to the
engine.
(4) Apply 1.5±2.0 mm (0.059±0.078 in.) bead of
MopartBed Plate Sealant to cylinder block as shown
in (Fig. 99).
(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. 100).(8) Install main bearing bedplate to engine block
bolts (1±10) and torque each bolt to 81 N´m (60 ft.
lbs.) in sequence shown in (Fig. 100).
(9) 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. 100).
(10) 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.).
(11) If crankshaft end play is to be checked, refer
to service procedures in this section.
(12) Install connecting rod bearings and caps.
Install new connecting rod bolts and tighten to 27
N´m (20 ft. lbs.) plus 1/4 turn.
(13) Install oil pump and crankshaft front oil seal.
(14) Install oil pick-up tube and oil pan. Refer to
procedure in the section.
(15) Install oil filter adapter and filter.
(16) Install lower torque strut/air conditioning
compressor mounting bracket to engine (Fig. 95).
