WARNING
WARNING: Exercise care when servicing clutch components. Factory installed clutch discs do not contain
asbestos fibers. Dust and dirt on clutch parts may contain asbestos fibers from aftermarket components.
Breathing excessive concentrations of these fibers can cause serious bodily harm. Wear a respirator during
service and never clean clutch components with compressed air or with a dry brush. Either clean the components with water dampened rags or use a vacuum cleaner specifically designed to remove asbestos
fibers and dust. Do not create dust by sanding a clutch discs. Replace the disc if the friction material is
damaged. Dispose of all dust and dirt containing asbestos fibers in sealed bags or containers. This will
minimize exposure to yourself and to others. Follow all recommended safety practices prescribed by the
occupational safety and health administration (OSHA) and the environmental safety agency (EPA), for the
handling and disposal of products containing asbestos. Failure to follow these instructions may result in
personal injury or death
DIAGNOSIS AND TESTING
CLUTCH
Road test and inspect components to determine a clutch problem. Road test the vehicle at normal speeds. Shift the
transmission through all gear ranges and observe clutch action. If clutch chatters, grabs, slips or does not release
properly, remove and inspect clutch components. If problem is noise or hard shifting, further diagnosis may be
needed to the transmission and driveline component.
CLUTCH CONTAMINATION
Contamination is a frequent cause of clutch malfunctions. Oil, water or clutch fluid on the clutch disc and pressure
plate surfaces will cause chatter, slip and grab. Oil contamination indicates a leak at either the rear main seal or
transmission input shaft. Clutch fluid leaks are usually from damaged slave cylinder push rod seals. Heat buildup
caused by slippage between the pressure plate, disc and flywheel can bake the oil residue onto the components.
The glaze-like residue ranges in color from amber to black.
Road splash contamination is dirt/water entering the clutch housing due to loose bolts, housing cracks. Driving
through deep water puddles can force water/road splash into the housing through such openings.
IMPROPER RELEASE OR CLUTCH ENGAGEMENT
Clutch release or engagement problems can be caused by worn or damage clutch components.
Release problems can cause hard shifting and noise. Look for leaks at clutch cylinders, connecting line and loose
slave cylinder bolts. Also worn/loose release fork, pivot stud, clutch disc, pressure plate or release bearing.
Engagement problems can cause slip, chatter/shudder and noisy operation. The causes may be clutch disc con-
tamination, wear, distortion or flywheel damage.
CLUTCH MISALIGNMENT
Clutch components must be in proper alignment with the crankshaft and transmission input shaft. Misalignment
caused by excessive runout or warpage of any clutch component will cause grab, chatter and improper clutch
release.
CLUTCH COVER AND DISC RUNOUT
Check the clutch disc before installation. Axial (face) runout of a new disc should not exceed 0.50 mm (0.020 in.).
Measure runout about 6 mm (1/4 in.) from the outer edge of the disc facing. Obtain another disc if runout is excessive.
Check condition of the clutch before installation. A warped cover or diaphragm spring will cause grab and incomplete release or engagement. Be careful when handling the cover and disc. Impact can distort the cover, diaphragm
spring, release fingers and the hub of the clutch disc.
Use an alignment tool when positioning the disc on the flywheel. The tool prevents accidental misalignment which
could result in cover distortion and disc damage.
DR CLUTCH 6 - 3
A frequent cause of clutch cover distortion (and consequent misalignment) is improper bolt tightening.
FLYWHEEL RUNOUT
Check flywheel runout whenever misalignment is suspected. Flywheel runout should not exceed 0.08 mm (0.003
in.). Measure runout at the outer edge of the flywheel face with a dial indicator.
Common causes of runout are:
• heat warpage
• improper machining
• incorrect bolt tightening
• improper seating on crankshaft flange shoulder
• foreign material on crankshaft flange
Flywheel machining is not recommended. The flywheel clutch surface is machined to a unique contour and machining will negate this feature. Minor flywheel scoring can be cleaned up by hand with 180 grit emery or with turning
equipment. Remove only enough material to reduce scoring (approximately 0.001 - 0.003 in.). Heavy stock removal
is not recommended. Replace the flywheel if scoring is severe and deeper than 0.076 mm (0.003 in.). Excessive
stock removal can result in flywheel cracking or warpage after installation; it can also weaken the flywheel and
interfere with proper clutch release.
Clean the crankshaft flange before mounting the flywheel. Dirt and grease on the flange surface may cock the flywheel causing excessive runout. Use new bolts when remounting a flywheel and secure the bolts with Mopar™
Lock And Seal or equivalent. Tighten flywheel bolts to specified torque only. Overtightening can distort the flywheel
hub causing runout.

INSTALLATION
CAUTION: Before installing a clutch disc on 5.9 L
Diesel with Dual Mass Flywheel and self-adjusting
pressure plate, the pressure plate must be reset.
Failure to reset the pressure will result in damage
to the clutch disc.
1. Check runout and free operation of new clutch
disc.
2. Lubricate crankshaft pilot bearing with a NLGI - 2
rated grease.
3. Install clutch alignment tool in clutch disc hub with
the raised side of hub is facing away from the flywheel.
NOTE: Flywheel side is imprinted on the disc face.
4. Install alignment tool (3) in pilot bearing and position disc on the flywheel (1).
5. Position pressure plate over disc (2) and onto the flywheel.
6. Align and hold pressure plate in position and install bolts finger tight.
7. Tighten bolts evenly and a few threads at a time in a diagonal pattern.
CAUTION: Bolts must be tightened evenly and to specified torque to avoid warping pressure plate cover.
8. Tighten pressure plate bolts to:
• V6 & V8 Engines - 50 N·m (37 ft. lbs.)
• V10 & Diesel Engines - 30 N·m (22 ft. lbs.)
9. Remove release lever (3) and release bearing from
clutch housing (1). Apply Mopar™ high temperature
bearing grease to bore (4) of release bearing,
release lever (5) contact surfaces and release lever
pivot stud (2).
