(17) Install the input clutch assembly into Input
Clutch Pressure Fixture 8260 (Fig. 87). Mount a dial
indicator to the assembly, push down on the clutch
discs and zero the indicator against the underdrive
clutch discs (Fig. 88). Apply 20 psi of air pressure to
the underdrive clutch and record the dial indicator
reading. Measure and record UD clutch pack mea-
surement in four (4) places, 90É apart. Take average
of four measurements and compare with UD clutch
pack clearance specification. The correct clutch clear-
ance is 0.84-1.54 mm (0.033-0.061 in.). The reaction
plate is not selective. If the clutch clearance is not
within specification, replace the reaction plate along
with all the friction and steel discs.
(18) Install the overdrive clutch pack into the
input clutch retainer (Fig. 86). The overdrive steel
separator plates can be identified by the lack of the
half-moon cuts in the locating tabs.
(19) Install the overdrive clutch wavy snap-ring
with the two tabbed ears into the input clutch
retainer.
(20) Install the OD/reverse reaction plate into the
input clutch retainer. The reaction plate is non-direc-
tional (Fig. 86).
(21) Install the OD/reverse reaction plate flat
snap-ring into the input clutch retainer.
(22) Mount a dial indicator to the assembly and
zero the indicator against the OD/reverse reaction
plate (Fig. 89). Apply 20 psi of air pressure to the
overdrive clutch and record the dial indicator read-ing. Measure and record OD clutch pack measure-
ment in four (4) places, 90É apart. Take average of
four measurements and compare with OD clutch
pack clearance specification.Verify that the clutch
clearance is 1.103-1.856 mm (0.043-0.073 in.). The
reaction plate is not selective. If the clutch clearance
is not within specification, replace the reaction plate
along with all the friction and steel discs.
(23) Install the reverse clutch pack into the input
clutch retainer (Fig. 86).

ROAD TESTING WIND NOISE
(1) Drive the vehicle to verify the general location
of the wind noise.
(2) Apply 50 mm (2 in.) masking tape in 150 mm
(6 in.) lengths along weatherstrips, weld seams or
moldings. After each length is applied, drive the vehi-
cle. If noise goes away after a piece of tape is applied,
remove tape, locate, and repair defect.
POSSIBLE CAUSE OF WIND NOISE
²Moldings standing away from body surface can
catch wind and whistle.
²Gaps in sealed areas behind overhanging body
flanges can cause wind-rushing sounds.
²Misaligned movable components.
²Missing or improperly installed plugs in pillars.
²Weld burn through holes.
STANDARD PROCEDURE
STANDARD PROCEDURE - BODY LUBRICATION
All mechanisms and linkages should be lubricated
when necessary. This will maintain ease of operation
and provide protection against rust and excessive
wear. The weatherstrip seals should be lubricated to
prolong their life as well as to improve door sealing.
All applicable exterior and interior vehicle operat-
ing mechanisms should be inspected and cleaned.
Pivot/sliding contact areas on the mechanisms should
then be lubricated.
(1) When necessary, lubricate the operating mech-
anisms with the specified lubricants.
(2) Apply silicone lubricant to a cloth and wipe it
on door seals to avoid over-spray that can soil pas-
senger's clothing.
(3) Before applying lubricant, the component
should be wiped clean. After lubrication, any excess
lubricant should be removed.
(4) The hood latch, latch release mechanism, latch
striker, and safety latch should be lubricated period-
ically.
(5) The door lock cylinders should be lubricated
twice each year (preferably autumn and spring).
²Spray a small amount of lock cylinder lubricant
directly into the lock cylinder.
²Apply a small amount to the key and insert it
into the lock cylinder.
²Rotate it to the locked position and then back to
the unlocked position several times.
²Remove the key. Wipe the lubricant from it with
a clean cloth to avoid soiling of clothing.
STANDARD PROCEDURE - HEAT STAKING
(1) Remove trim panel.(2) Bend or move the trim panel components at
the heat staked joints. Observe the heat staked loca-
tions and/or component seams for looseness.
(3) Heat stake the components.
(a) If the heat staked or component seam loca-
tion is loose, hold the two components tightly
together and using a soldering gun with a flat tip,
melt the material securing the components
together. Do not over heat the affected area, dam-
age to the exterior of the trim panel may occur.
(b) If the heat staked material is broken or miss-
ing, use a hot glue gun to apply new material to
the area to be repaired. The panels that are being
heat staked must be held together while the apply-
ing the glue. Once the new material is in place, it
may be necessary to use a soldering gun to melt
the newly applied material. Do not over heat the
affected area, damage to the exterior of the trim
panel may occur.
(4) Allow the repaired area to cool and verify the
repair.
(5) Install trim panel.
STANDARD PROCEDURE - PLASTIC BODY
PANEL REPAIR
There are many different types of plastics used in
today's automotive environment. We group plastics in
three different categories: Rigid, Semi-Rigid, and
Flexible. Any of these plastics may require the use of
an adhesion promoter for repair. These types of plas-
tic are used extensively on DaimlerChrysler Motors
vehicles. Always follow repair material manufactur-
er's plastic identification and repair procedures.
Rigid Plastics:
Examples of rigid plastic use: Fascias, Hoods,
Doors, and other Body Panels, which include SMC,
ABS, and Polycarbonates.
Semi-Rigid Plastics:
Examples of semi-rigid plastic use: Interior Panels,
Under Hood Panels, and other Body Trim Panels.
Flexible Plastics:
Examples of flexible plastic use: Fascias, Body
Moldings, and upper and lower Fascia Covers.
Repair Procedure:
The repair procedure for all three categories of
plastics is basically the same. The one difference is
the material used for the repair. The materials must
be specific for each substrate, rigid repair material
for rigid plastic repair, semi-rigid repair material for
semi-rigid plastic repair and flexible repair material
for flexible plastic repair.

BODY (Continued)

Adhesion Promoter/Surface Modifier:
Adhesion Promoters/Surface Modifiers are required
for certain plastics. All three categories may have
plastics that require the use of adhesion promoter/
surface modifiers. Always follow repair material man-
ufacturer's plastic identification and repair
procedures.
SAFETY PRECAUTION AND WARNINGS
WARNING:
²EYE PROTECTION SHOULD BE USED WHEN
SERVICING COMPONENTS. PERSONAL INJURY
CAN RESULT.
²USE AN OSHA APPROVED BREATHING MASK
WHEN MIXING EPOXY, GRINDING, AND SPRAYING
PAINT OR SOLVENTS IN A CONFINED AREA. PER-
SONAL INJURY CAN RESULT.²AVOID PROLONGED SKIN CONTACT WITH
RESIN, PETROLEUM, OR ALCOHOL BASED SOL-
VENTS. PERSONAL INJURY CAN RESULT.
²DO NOT VENTURE UNDER A HOISTED VEHI-
CLE THAT IS NOT PROPERLY SUPPORTED ON
SAFETY STANDS. PERSONAL INJURY CAN
RESULT.
NOTE:
²When holes must be drilled or cut in body pan-
els, verify locations of internal body components
and electrical wiring. Damage to vehicle can result.
²Do not use abrasive chemicals or compounds
on undamaged painted surfaces around repair
areas. Damage to finish can result.
