DESCRIPTION
CLUTCH COMPONENTS
Models equipped with a 2.4L Gas engine utilize a
modular clutch assembly (Fig. 1). The modular clutch
consists of a single, dry-type clutch disc, a diaphragm
style clutch cover, and an integrated flywheel. The
clutch cover (pressure plate) is riveted to the fly-
wheel, and therefore can only be serviced as an
assembly.
Models equipped with the 2.5L Turbo Diesel engine
utilize a conventional clutch system (Fig. 2). This
system consists of a flywheel, clutch disc, and clutch
cover (pressure plate), which is fastened to the fly-
wheel, capturing the clutch disc within. Each compo-
nent is individually serviceable, however it ishighly
recommended that the clutch cover and disc be
replaced as a set.

CHRYSLER VOYAGER 2004 Service Manual DIAGNOSIS AND TESTING - DRIVE PLATE
MISALIGNMENT
Common causes of misalignment are:
²Heat warping
²Mounting drive plate on a dirty crankshaft

²Incorrect bolt tightening
²Improper seating on

DIAGNOSIS AND TESTING - DRIVE PLATE
MISALIGNMENT
Common causes of misalignment are:
²Heat warping
²Mounting drive plate on a dirty crankshaft
flange
²Incorrect bolt tightening
²Improper seating on the crankshaft shoulder
²Loose crankshaft bolts
Clean the crankshaft flange before mounting the
drive plate. Dirt and grease on the flange surface
may misalign the flywheel, causing excessive runout.
Use new bolts when mounting drive plate to crank-
shaft. Tighten drive plate bolts to specified torque
only. Over-tightening can distort the drive plate hub
causing excessive runout.
DIAGNOSIS AND TESTING - CLUTCH COVER
AND DISC RUNOUT
Check condition of the clutch cover before installa-
tion. A warped cover or diaphragm spring will cause
grab and/or incomplete release or engagement. Use
care when handling the clutch assembly. Impact can
distort the cover, diaphragm spring, and release fin-
gers.
DIAGNOSIS AND TESTING - CLUTCH CHATTER
COMPLAINTS
For all clutch chatter complaints, perform the fol-
lowing:
(1) Check for loose, misaligned, or broken engine
and transmission mounts. If present, they should be
corrected at this time. Test vehicle for chatter. If
chatter is gone, there is no need to go any further.
(2) If chatter persists, check hydraulic clutch
release system is functioning properly.
(3) Check for loose connections in drivetrain. Cor-
rect any problems and determine if clutch chatter
complaints have been satisfied. If not:
(a) Remove transaxle.
(b) Check to see if the release bearing is sticky
or binding. Replace bearing, if needed.
(c) Check linkage for excessive wear on the pivot
stud and fork fingers. Replace all worn parts.
(d) Check clutch assembly for contamination
(dirt, oil). Replace clutch assembly, if required.
(e) Check to see if the clutch disc hub splines
are damaged. Replace with new clutch assembly, if
necessary.
(f) Check input shaft splines for damage.
Replace, if necessary.
(g) Check for uneven wear on clutch fingers.
(h) Check for broken clutch cover diaphragm
spring fingers. Replace with new clutch assembly,
if necessary.
