REMOVAL
1) Remove rear axle shaft. Refer to REAR AXLE SHAFT RE-
MOVAL in Section 3E.
2) In order to remove sensor rotor from retainer ring, grind with a
grinder one part of the sensor rotor as illustrated till it becomes
thin.
CAUTION:
Cover vinyl sheet or the like over wheel bearing so that
fine grains from grinding will not enter there.
Be careful not to go so far as to grind the retainer ring.
3) Break with a chisel the thin ground sensor rotor, and it can be re-
moved.
INSTALLATION
1) Press-fit sensor rotor as shown.
NOTE:
Use care not to cause any damage to outside of retainer
ring.
2) Install rear axle shaft. Refer to REAR AXLE SHAFT INSTALLA-
TION in Section 3E.

As the aluminum case is sealed with liquid type gas-
ket, it is necessary to use genuine sealant or its equiv-
alent on its mating surfaces when reassembling it.
Also, the case fastening bolts must be tightened to
specified torque by means of the torque wrench and
tightening over or below the specified torque should
be avoided.
The description under ON-VEHICLE SERVICE in this
section covers a part of the TYPE 2 manual transmis-
sion and the transfer. The transfer is next to the trans-
mission as well, but their gear boxes are independent
and each of them has its own drain and level / filler
plugs for the oil change or the level check.
For the repair procedure of the transfer unit, refer to
Section 7D.
SECTION 7A
MANUAL TRANSMISSION
(TYPE 1)
CONTENTS
GENERAL DESCRIPTION
The manual transmission consists of the input shaft,
main shaft, countershaft and reverse gear which are
installed in the aluminum case. Its gears are of for-
ward five speeds in synchro mesh and reverse one
speed in constant mesh system.
The main shaft gears are held by the needle bearings
and on them the synchronizer rings and synchronizer
sleeve & hubs are assembled.
The gear shift lever case is located at the upper be-
hind the transmission case and has a cam which pre-
vents direct gear shift from the 5th speed gear to the
reverse gear.

7C1-2 CLUTCH
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 torsional coil springs, is positioned
on the transmission input shaft with an involute spline
fit.
The clutch cover is secured to the flywheel, and car-
ries the diaphragm spring in such a way that the pe-
ripheral edge part of the spring pushes on the pres-
sure plate against the flywheel (with the disc in be-
tween), when the clutch release bearing is held back.
This is the engaged condition of the clutch.Depressing the clutch pedal causes the release bear-
ing to advance and pushes on the tips of the tapered
fingers 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 transmis-
sion input shaft.
