Specifications

(9) Install adaptor plate and tighten bolts to 47
N·m (35 ft. lbs.).
(10) Install bolts to main bearing carrier and
tighten to 26.5 N·m (20 ft. lbs.).
(11) Position flywheel and O-ring on crankshaft
and align bolt holes.
NOTE: For purposes of checking crankshaft end
play used flywheel bolts may be used. Final assem-
bly requires new flywheel bolts.
(12) Install 2 flywheel bolts, 180° apart, and
tighten bolts to 20 N·m plus 60° (15 ft. lbs.) plus 60°.
(13) Attach dial indicator to engine block.
(14) Move crankshaft toward front of engine and
zero indicator.
(15) Move crankshaft toward the rear of engine
and record measurement.
(16) Subtract specified crankshaft end play from
figure obtained. Crankshaft end play 0.08 to 0.21 mm
(0.0032 to 0.0083 in.).
(17) Select thrust washers which will give correct
end play.
(18) Remove tools and flywheel.
(19) Lubricate thrust washer halves and fit them
into the rear main bearing carrier.
(20) To verify correct end play, install 2 flywheel
bolts 180° apart, and tighten bolts to 20 N·m plus 60°
(15 ft. lbs. plus 60°).
(21) Measure crankshaft end play with a dial
gauge. Crankshaft end play should not exceed 0.08-
0.21 mm (0.0032 to 0.0083 in.) (Fig. 57). If end clear-
ance exceeds these values install oversize thrust
washer.
CAUTION: Use NEW flywheel bolt for the following
procedure.
(22) Install new O-ring on flywheel. Install fly-
wheel. The 6 flywheel bolts must be tightened as fol-
lows:
a. Torque the 6 flywheel bolts to 60 N·m (44 ft.
lbs.).
b. Loosen 2 of the 6 bolts, 180° apart. Torque the 2
bolts to 20 N·m (180 in. lbs.). Then using a torque
angle gauge rotate the 2 bolts 65° additional.
c. Loosen the next 2 bolts, 180° apart and follow
the same procedure.
d. Loosen the last 2 bolts, 180° apart and follow
the same procedure.
(23) Install Transmission. Refer to procedure in
Group 21, Transmission.
(24) Install pistons and connecting rod assemblies,
refer to piston and connecting rods in this section.
(25) Install oil pick up tube and tighten bolts to 25
N·m (18 ft. lbs.).
(26) Install oil pan, refer to oil pan installation in
this section.
(27) Install timing chain. Refer to procedure in
this section.
(28) Install vacuum pump. Tighten retaining
screws to 20 N·m (15 ft. lbs.).
