(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. Then torque these bolts to 28 N·m (20 ft.
lbs.).
(8) Install main bearing bedplate to engine block
bolts (1 through 10) and torque each bolt to 41 N·m
(30 ft. lbs.) in sequence then in sequence turn each
bolt 1/4 turn shown in (Fig. 14).
(9) Install main bearing bedplate to engine block
bolts (11 through 20), and torque each bolt to 28 N·m
(20 ft. lbs.) in sequence shown in (Fig. 14).
(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.).
CRANKSHAFT END PLAY
Fig. 15 Checking Crankshaft End Play—Typical
(1) Mount a dial indicator to front of engine, locat-
ing probe on nose of crankshaft (Fig. 15).
(2) Move crankshaft all the way to the rear of its
travel.
(3) Zero the dial indicator.
(4) Move crankshaft all the way to the front and
read the dial indicator. Refer to Crankshaft Specifi-
cation Table for end-play specification.
CRANKSHAFT SPECIFICATION TABLE
Crankshaft End-Play
New Part: 0.09 - 0.24mm (0.0035 - 0.0094 in.)
Wear Limit: 0.37 mm (0.015 in.)
OPTIONAL CRANKSHAFT END PLAY CHECK
(1) Move crankshaft all the way to the rear of its
travel using a lever inserted between a main bearing
cap and a crankshaft cheek, using care not to dam-
age any bearing surface. DO NOT loosen main bear-
ing cap.
(2)
Use a feeler gauge between number three
thrust bearing and machined crankshaft surface to
determine end play.
CAMSHAFT END PLAY
(1)
Oil camshaft journals and install camshaft
WITHOUT cam follower assemblies. Install rear cam
caps and tighten screws to specified torque.
(2)
Using a suitable tool, move camshaft as far
rearward as it will go.
(3) Zero dial indicator (Fig. 16).
(4) Move camshaft as far forward as it will go.
(5) End play travel: 0.05 - 0.15 mm (0.002 - 0.010
in.).
(6) If end play is excessive check cylinder head and
camshaft for wear; replace as necessary.
