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.

INSPECTION
Input Shaft Bearing
Check bearing (1) for smooth rotation and replace it if abnormality
is found.
Clutch Disc
Measure depth of rivet head depression, i.e. distance between
rivet head and facing surface. If depression is found to have
reached service limit at any of holes, replace disc assembly.
Rivet head depth
Standard : 1.65 – 2.25 mm (0.06 – 0.09 in.)
Service limit : 0.5 mm (0.02 in.)
Clutch Cover
1) Check diaphragm spring (1) for abnormal wear or damage.
2) Inspect pressure plate (2) for wear or heat spots.
3) If abnormality is found, replace it as assembly. Do not disas-
semble it into diaphragm and pressure plate.
Flywheel
Check surface contacting clutch disc for abnormal wear or heat
spots. Replace or repair as required.

INSTALLATION
1) Install flywheel (1) to crankshaft and tighten bolts (2) to spec-
ification.

2) Using special tool, install input shaft bearing to flywheel.
Special tool
(B) : 09925-98210
3) Aligning clutch disc to flywheel center by using special tool,
install clutch cover (1) and bolts. Then tighten bolts to speci-
fication.
Special tool
(A) : 09924-17810
(C) : 09923-36320
Tightening torque
Clutch cover bolts (b) : 23 N·m (2.3 kg-m, 16.5 lb-ft) NOTE:
Before assembling, make sure that flywheel surface and
pressure plate surface have been cleaned and dried thor-
oughly.
NOTE:
While tightening clutch cover bolts, compress clutch
disc with special tool (C) by hand so that disc cen-
tered.
Tighten cover bolts little by little evenly in diagonal
order.

7F-2 REAR DIFFERENTIAL
GENERAL DESCRIPTION
The differential assembly uses a hypoid bevel pinion and gear.
The differential assembly is decisive in that the drive power is concentrated there. Therefore, use of genuine
parts and specified torque is compulsory. Further, because of sliding tooth meshing with high pressure between
bevel pinion and gear, it is mandatory to lubricate them by hypoid gear oil.
VISCOUS COUPLING
The 4WD vehicle is equipped with a viscous coupling (1) in front of the rear differential.
The 4WD mechanism used for this vehicle distributes optimum driving force to the front and rear wheels accord-
ing to road conditions and driving conditions.
