CAMSHAFT & BEARINGS (IN BLOCK) (Continued)
Camshaft Gear
Inspect the camshaft gear for cracks (gear and
hub) (Fig. 95), and chipped/broken/fretted teeth (Fig.
96). If replacement is necessary, (Refer to 9 -
ENGINE/ENGINE BLOCK/CAMSHAFT & BEAR-
INGS (IN BLOCK) - REMOVAL).
Fig. 95 Inspect Camshaft Gear Hub for Cracks
Fig. 96 Inspect Camshaft Gear for Cracks and
Thrust Plate
Inspect the camshaft thrust plate for excessive
wear in the camshaft contact area. Measure thrust
plate thickness using the CAMSHAFT THRUST
PLATE THICKNESS CHART. Replace any thrust
plate that falls outside of these specifications:
CAMSHAFT THRUST PLATE THICKNESS
9.34 mm (0.368 in.) MIN.
9.58 mm (0.377 in.) MAX.

INSTALLATION—CAMSHAFT BEARINGS
(1) Apply a coating of Loctite 640 Adhesive to the
backside of the new bushing. Avoid getting adhesive
in the oil hole.
(2) Use a universal cam bushing installation tool
and install the bushing so that it is even with the
front face of the cylinder block. The oil hole must be
aligned. A 3.2 mm (0.128 inch) diameter rod must be
able to pass through the hole (Fig. 97).
(3) Measure the installed bushing. The limit of the
inside diameter is 54.133 mm (2.1312 inch).

INSTALLATION—CAMSHAFT
(1) Lubricate the camshaft bushing and bores with
fresh engine oil or suitable equivalent.
(2) Liberally coat the camshaft lobes, journals, and
thrust washer with fresh engine oil or suitable equiv-
alent.
CAUTION: When installing the camshaft (Fig. 91),
DO NOT push it in farther than it will go with the
thrust washer in place. Pushing it too far can dis-
lodge the plug in the rear of the camshaft bore and
cause an oil leak.
(3) Install the camshaft (Fig. 91) and thrust plate.
Align the timing marks as shown in (Fig. 89).
(4) Install the thrust plate bolts and tighten to 24
N·m (18 ft. lbs.) torque.
(5) Measure camshaft back lash and end clearance
(Fig. 98).
(6) Remove the wooden dowel rods and rubber
bands from the tappets.
(7) Lubricate the push rods with engine oil and
install in their original location (Fig. 87). Verify that
they are seated in the tappets.
(8) Lubricate the valve tips with engine oil and
install the crossheads in their original locations.
(9) Lubricate the crossheads and push rod sockets
with engine oil and install the rocker arms and ped-
estals in their original locations (Fig. 86). Tighten
bolts to 36 N·m (27 ft. lbs.) torque.
