DESCRIPTION AND OPERATION
MODULAR CLUTCH ASSEMBLY
All 2.0L SOHC engines equipped with the A578
5-speed transaxle use a modular clutch assembly
(Fig. 1). The transaxle must be removed to gain
access to and replace the modular clutch, drive plate,
and/or clutch release bearing and lever.
The modular clutch assembly used in this vehicle
consists of a single, dry-type clutch disc, a diaphragm
style clutch cover, and an integrated flywheel. The
clutch cover is riveted to the flywheel, containing theclutch disc within. The modular clutch can only be
serviced as an assembly.
The clutch disc has cushion springs riveted to the
disc hub assembly. The clutch disc facings are riveted
to the cushion springs. The facings are made from a
non-asbestos material.
The clutch cover pressure plate assembly is a dia-
phragm type unit with a one-piece diaphragm spring
with multiple release fingers. The pressure plate
release fingers are preset during manufacture and
are not adjustable.
CLUTCH CABLE
The clutch cable assembly (Fig. 2) carries the
movement of the clutch pedal to the clutch release
bearing. The cable is designed to maintain tension
against the clutch fork, or lever, and has a built in
self-adjusting mechanism, which compensates for
clutch disc wear.
CLUTCH INTERLOCK/UPSTOP SWITCH
DESCRIPTION
The clutch interlock/upstop switch is an assembly
consisting of two switches: an engine starter inhibit
switch (interlock) and a clutch pedal upstop switch
(Fig. 3). The switch assembly is located in the clutch/
brake pedal bracket assembly (Fig. 4), each switch
being fastened by four plastic wing tabs.
OPERATION
Clutch Interlock Switch
The clutch interlock switch prevents engine starter
operation and inadvertent vehicle movement with the
clutch engaged and the transaxle in gear.

DIAGNOSIS AND TESTING (Continued)

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.
CLUTCH CHATTER COMPLAINTS
For all clutch chatter complaints, do the following:
(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. If
chatter persists:
(2) Check to see if clutch cable routing is correct
and operates smoothly.
(3) Check for loose connections in drive train. Cor-
rect any problems and determine if clutch chatter
complaints have been satisfied. If not:
(4) Remove transaxle. See Group 21, Manual Tran-
saxle for procedure.
(5) Check to see if the release bearing is sticky or
binding. Replace bearing, if needed.
(6) Check linkage for excessive wear on the pivot
stud and fork fingers. Replace all worn parts.
(7) Check clutch assembly for contamination (dirt,
oil). Replace clutch assembly, if required.
(8) Check to see if the clutch disc hub splines are
damaged. Replace with new clutch assembly, if nec-
essary.
(9) Check input shaft splines for damage. Replace,
if necessary.
(10) Check for uneven wear on clutch fingers.
(11) Check for broken clutch cover diaphragm
spring fingers. Replace with new clutch assembly, if
necessary.
CLASH±INTO±REVERSE COMPLAINTS
Certain NV T350 (A-578) manual transaxles are
equipped with a reverse brake. It prevents clash
when shifting into reverse, but only if the vehicle is
not moving. See Group 21, Transaxle for further
diagnosis.
(1) Depress clutch pedal to floor and hold. After
three seconds, shift to reverse. If clash is present,
clutch has excessive spin time, and the reverse brake
may not be functioning.(2) Remove transaxle. See Group 21, Manual Tran-
saxle for procedure.
(3) Check the input shaft spline, clutch disc
splines, and release bearing for dry rust. If present,
clean rust off and apply a light coat of bearing grease
to the input shaft splines. Apply grease on the input
shaft splines only where the clutch disc slides. Verify
that the clutch disc slides freely along the input shaft
spline.
(4) Check to see if the clutch disc hub splines are
damaged, and replace with new clutch assembly if
required.
(5) Check the input shaft for damaged splines.
Replace as necessary.
(6) Check for broken clutch cover diaphragm
spring fingers.
(7) Install clutch assembly and transaxle.
CLUTCH INTERLOCK/UPSTOP SWITCH
The clutch interlock/upstop switch is an assembly
consisting of two switches: an engine starter inhibit
switch (clutch interlock) and a clutch pedal upstop
switch (Fig. 5). The switch assembly is located in the
clutch/brake pedal bracket assembly (Fig. 6), each
switch being fastened by four plastic wing tabs.
CLUTCH INTERLOCK SWITCH
Mechanical Test
(1) With the park brake set and the transaxleIN
NEUTRAL,turn the ignition key to the start posi-
tion. The engine starter should not crank with the
clutch pedal at rest (not depressed). If the starter
cranks, proceed to the electrical test to determine
whether the switch is defective or the circuit is
shorted. If the vehicle does not crank, proceed to the
next step.
(2) With the park brake set and the transaxleIN
NEUTRAL,fully depress the clutch pedal and turn
