7C-2 CLUTCH
GENERAL DESCRIPTION
The clutch is a diaphragm-spring clutch of a dry single disc type. The diaphragm spring is of a tapering-finger
type, which is a solid ring in the outer diameter part, with a series of tapered fingers pointing inward.
The disc, carrying four torsional coil springs, is positioned on the transmission input shaft with an involute spline
fit.
The clutch cover is secured to the flywheel, and carries the diaphragm spring in such a way that the peripheral
edge part of the spring pushes on the pressure plate against the flywheel (with the disc in between), when the
clutch release bearing is held back. This is the engaged condition of the clutch.
Depressing the clutch pedal causes the release bearing to advance and pushes on the tips of the tapered fin-
gers of the diaphragm spring. When this happens, the diaphragm spring pulls the pressure plate away from the
flywheel, thereby interrupting the flow of drive from flywheel through clutch disc to transmission input shaft.

UNIT INSTALLATION
Install transfer assembly (2) by reversing removal procedure and
noting following points.
Tighten transfer mounting bolts (3) to specified torque.
Tightening torque
Transfer mounting bolts (a) : 50 N·m (5.0 kg-m, 36.5 lb-ft)
Tighten rear mounting bracket bolts (1) to specified torque.
Tightening torque
Transfer rear mounting bracket bolts
(a) : 55 N·m (5.5 kg-m, 40.0 lb-ft)These contact patterns indicate that the “offset” of
reduction driven gear is too much or too little. The rem-
edy is to change the division of the bevel gear shim(s).
These contact patterns, located on toe or heel on both
drive and coast sides, mean that 1) both pinion and
gear are defective, 2) retainer is not true, or 3) gear is
not properly seated on transfer case. The remedy is to
replace the defective member.
Irregular patterns: If the pattern is not oval, it means
that bevel gear is defective. High or low spots on tooth
surfaces or on the seat of bevel gear are the cause of
irregular patterns appearing on some teeth. The rem-
edy is to replace the pinion and gear set and, if the seat
is defective, so is transfer case. TOOTH CONTACT PATTERN DIAGNOSIS AND REMEDY
