Dodge RAM TRUCK 1500 1995 Service Manual page 874

(2) Insert a 6.850 mm (1/4 inch) spacer between
rocker arm pad and stem tip of No.l intake valve. Al­
low spring load to bleed tappet down giving in effect
a solid tappet.
(3) Install a dial indicator so plunger contacts'
valve spring retainer as nearly perpendicular as pos­
sible. Zero the indicator.
(4) Rotate the crankshaft clockwise (normal run­
ning direction) until the valve has lifted 0.254 mm
(0.010 inch). The timing of the crankshaft should
now read from 10° before top dead center to 2° after
top dead center. Remove spacer.
CAUTION: DO NOT turn crankshaft any further
clockwise as valve spring might bottom and result
in serious damage.
(5) If reading is not within specified limits:
(a) Check sprocket index marks.
(b) Inspect timing chain for wear.
(c) Check accuracy of DC mark on timing indica­
tor.
VIBRATION DAMPER
REMOVAL
(1) Disconnect the negative cable from the battery.
(2) Remove fan shroud retainer bolts and set
shroud back over engine.
(8) Remove the cooling system fan.
(4) Remove the serpentine belt (refer to Group 7,
Cooling System).
(5) Remove the vibration damper pulley.
(6) Remove vibration damper bolt and washer from
end of crankshaft.
(7) Install bar and screw from Puller Tool Set
C-3688. Install 2 bolts with washers through the
puller tool and into the vibration damper (Fig. 1).
Fig. 1 Vibration Damper Assembly
(8) Pull vibration damper off of the crankshaft.
INSTALLATION
(1) Position the vibration damper onto the crank­
shaft.
(2) Place installing tool, part of Puller Tool Set
C-3688 in position and press the vibration damper
onto the crankshaft (Fig. 2).
Fig. 2 Installing Vibration Damper
(3) Install the crankshaft bolt and washer. Tighten
the bolt to 183 N-m (135 ft. lbs.) torque.
(4) Install the crankshaft pulley. Tighten the pul­
ley bolts to 23 N-m (200 in. lbs.) torque.
(5) Install the serpentine belt (refer to Group 7,
Cooling System).
(6) Install the cooling system fan. Tighten the bolts
to 23 N-m (17 ft. lbs.) torque.
(7) Position the fan shroud and install the bolts.
Tighten the retainer bolts to 11 N-m (95 in. lbs.)
torque.
(8) Connect the negative cable to the battery.
TIMING CHAIN COVER
REMOVAL
(1) Disconnect the negative cable from the battery.
(2) Drain cooling system (refer to Group 7, Cooling
System).
(3) Remove the serpentine belt (refer to Group 7,
Cooling System).
(4) Remove water pump (refer to Group 7, Cooling
System).
(5) Remove power steering pump (refer to Group
19, Steering).
(6) Remove vibration damper.
(7) Loosen oil pan bolts and remove the front bolt
at each side.
(8) Remove the cover bolts.
(9) Remove chain case cover and gasket using ex­
treme caution to avoid damaging oil pan gasket.
(10) Place a suitable tool behind the lips of the oil
seal to pry the oil seal outward. Be careful not to
damage the crankshaft seal surface of cover (Fig. 3).
TIMING CHAIN STRETCH
(1) Place a scale next to the timing chain so that
any movement of the chain may be measured.
(2) Place a torque wrench and socket over cam­
shaft sprocket attaching bolt. Apply torque in the di­
rection of crankshaft rotation to take up slack; 41
