2002 DODGE RAM seat adjustment

INSTALLATION
(1) If previously removed, install the push rods in
their original location (Fig. 62).Verify that they
are seated in the tappets.
(2) Lubricate the valve tips and install the cross-
heads in their original locations.
(3) Lubricate the crossheads and push rod sockets
and install the rocker arms and pedestals (Fig. 60) in
their original locations. Tighten bolts to 36 N´m (27
ft. lbs.) torque.
(4)Verify valve lash adjustment (Refer to 9 -
ENGINE/CYLINDER HEAD/INTAKE/EXHAUST
VALVES & SEATS - STANDARD PROCEDURE).
(5) Install cylinder head cover and reusable gasket
(Fig. 59) (Refer to 9 - ENGINE/CYLINDER HEAD/
CYLINDER HEAD COVER(S) - INSTALLATION).
(6) Connect battery negative cables.
ENGINE BLOCK
STANDARD PROCEDURE
STANDARD PROCEDURE - CYLINDER BLOCK
REFACING
(1) The combustion deck can be refaced twice. The
first reface should be 0.25 mm (0.0098 inch). If addi-
tional refacing is required, an additional 0.25 mm
(0.0098 inch) can be removed. Total allowed refacing
is 0.50 mm (0.0197 inch) - (Fig. 68).
(2) The upper right corner of the rear face of the
block must be stamped with a X when the block is
refaced to 0.25 mm (0.0098 inch). A second X must be
stamped beside the first when the block is refaced to
0.50 mm (0.0197 inch) - (Fig. 69).
(3) Consult the parts catalog for the proper head
gaskets which must be used with refaced blocks to
ensure proper piston-to-valve clearance.
STANDARD PROCEDURE - CYLINDER BORE -
DE-GLAZE
(1) New piston rings may not seat in glazed cylin-
der bores.
(2) De-glazing gives the bore the correct surface
finish required to seat the rings. The size of the bore
is not changed by proper de-glazing.
(3) Cover the lube holes in the top of the block
with waterproof tape.
(4) A correctly honed surface will have a cross-
hatch appearance with the lines at 15É to 25É angles
(Fig. 70). For the rough hone, use 80 grit honing
stones. To finish hone, use 280 grit honing stones.
(5) Use a drill, a fine grit Flex-hone and a mixture
of equal parts of mineral spirits and SAE 30W engine
oil to de-glaze the bores.(6) The crosshatch angle is a function of drill
speed and how fast the hone is moved vertically (Fig.
71).
(7) Vertical strokes MUST be smooth continuous
passes along the full length of the bore (Fig. 71).
(8) Inspect the bore after 10 strokes.
(9) Use a strong solution of hot water and laundry
detergent to clean the bores. Clean the cylinder bores
immediately after de-glazing.

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:

INSTALLATION
INSTALLATIONÐCAMSHAFT BEARINGS
(1) Apply a coating of Loctitet640 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).
INSTALLATIONÐCAMSHAFT
(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.
(10)Verify valve lash adjustment (Refer to 9 -

KEY-IN IGNITION SWITCH
DESCRIPTION
The key-in ignition switch is integral to the igni-
tion switch, which is mounted on the left side of the
steering column. It closes a path to ground for the
Central Timer Module (CTM) when the ignition key
is inserted in the ignition lock cylinder and the
driver door ajar switch is closed (driver door is open).
The key-in ignition switch opens the ground path
when the key is removed from the ignition lock cyl-
inder. The ground path is also opened when the
driver door ajar switch is open (driver door is closed).The key-in ignition switch cannot be repaired and,
if faulty or damaged, the entire ignition switch must
be replaced, (Refer to 19 - STEERING/COLUMN/IG-
NITION SWITCH - REMOVAL).

INPUT SHAFT END PLAY CHECK
NOTE: Overdrive unit must be installed in order to
correctly measure the input shaft end-play.
(1) Measure input shaft end play (Fig. 62).
NOTE: If end play is incorrect, transmission is
incorrectly assembled, or reaction shaft thrust
washer is incorrect. The reaction shaft thrust
washer is selective.
(a) Attach Adapter 8266-5 to Handle 8266-8.
(b) Attach dial indicator C-3339 to Handle
8266-8.
(c) Install the assembled tool onto the input
shaft of the transmission and tighten the retaining
screw on Adapter 8266-5 to secure it to the input
shaft.
(d) Position the dial indicator plunger against a
flat spot on the oil pump and zero the dial indica-
tor.
(e) Move input shaft in and out and record read-
ing. End play should be 0.86-2.13 mm (0.034-0.084
in.). Adjust as necessary.
ACCUMULATOR, VALVE BODY, OIL PAN, AND
TORQUE CONVERTER
(1) Install accumulator inner spring, piston and
outer spring (Fig. 63).(2) Verify that park/neutral position switch has
notbeen installed in case. Valve body can not be
installed if switch is in position.
(3) Install new valve body manual shaft seal in
case (Fig. 64). Lubricate seal lip and manual shaft
with petroleum jelly. Start seal over shaft and into
case. Seat seal with 15/16 inch, deep well socket.
(4) Install valve body as follows:
(a) Start park rod into park pawl. If rod will not
slide past park pawl, pawl is engaged in park gear.
Rotate overdrive output shaft with suitable size 12
point socket; this will free pawl and allow rod to
engage.
(b) Align and seat valve body on case. Be sure
manual lever shaft and overdrive connector are
fully seated in case.
(c) Install and start all valve body attaching
bolts by hand. Then tighten bolts evenly, in a diag-
onal pattern to 12 N´m (105 in. lbs.) torque.Do
not overtighten valve body bolts. This could
result in distortion and cross leakage after
installation..
(5) Install new filter on valve body. Tighten filter
screws to 4 N´m (35 in. lbs.).
(6) Install seal on park/neutral position switch.
Then install and tighten switch to 34 N´m (25 ft.
lbs.).
CAUTION: If the condition of the transmission
before the overhaul procedure caused excessive
metallic or fiber contamination in the fluid, replace
the torque converter and reverse flush the cooler(s)
and cooler lines. Fluid contamination and transmis-
sion failure can result if not done.
(7) Install torque converter. Use C-clamp or metal
strap to hold converter in place for installation.
