INSPECTION
Check pipe and hose for dent, kink, crack, dirt and dust. Replace
if check result is not satisfactory.
INSTALLATION
Reverse removal sequence noting following points.
Tighten flare nuts to specified torque.
Tightening Torque
(a): 16 N
.m (1.6 kg-m, 11.5 lb-ft)
NOTE:

For air bleeding of master cylinder alone, it must be removed
from vehicle.
(For procedures of removal and installation of master cylin-
der assembly and air bleeding, refer to CLUTCH MASTER

or other parts.

Install each clamp securely.

Install E-ring securely as shown.

After installation, check clutch pedal free travel and bleed air
from system.

Check fluid leakage.

Add fluid close to MAX level of reservoir.

INSTALLATION
1) To bleed air from master cylinder itself, tilt it as shown in figure
and add fluid into it.
NOTE:
After bleeding air from master cylinder, plug pipe hole in it
to prevent fluid from spilling out of it till pipe is connected.
2) Install master cylinder assembly and new gasket to body, attach-
ing bolt, nuts and push rod clevis pin.
NOTE:
Do not reuse gasket.
3) Torque attaching bolt and nut to specification.
4) Connect fluid pipe and torque flare nut to specification.

5) Apply grease to clevis pin and install it.
ªAº: Grease 99000-25010
6) Fill reservoir with specified brake fluid and check fluid leakage.
7) After installation, bleed air from system and check clutch pedal
free travel. Refer to BRAKE section for air bleeding procedure.
FLUID INSPECTION
Fluid level should be always between MIN and MAX lines on reser-
voir. If fluid decreases quickly, check for leakage, repair leaky point,
if any, and add fluid up to MAX level.
NOTE:

Brake fluid damages painted surface badly. Should it get on
painted surface, remove it immediately and clean surface
thoroughly.

Do not use shock absorber fluid or any other fluid which con-
tains mineral oil. Do not use container which has been used
for mineral oil or which is wet from water. Mineral oil will
cause swelling and distortion of rubber parts in hydraulic
clutch system and water will mix with brake fluid, lowering
fluid boiling point. Keep all fluid containers capped to pre-
vent contamination.

Make sure not to use fluid whose container cap was first
opened more than a year ago.

DISASSEMBLY
1) Remove boot and then circlip with piston pushed in.
2) Remove push rod and blow compressed air gradually into hole
for pipe connection to remove piston assembly, using care to
prevent it from jumping out.
INSPECTION
Inspect all disassembled parts for wear or damage and replace
parts if necessary.
NOTE:

Wash disassembled parts with brake fluid.

Do not reuse piston assembly and circlip.
Inspect cylinder bore for scoring or corrosion. It is best to replace
corroded cylinder. Corrosion can be identified as pits or excessive
roughness.
NOTE:
Polishing bore of cylinder with anything abrasive is prohib-
ited, as damage to cylinder bore may occur.
Rinse cylinder in clean brake fluid. Shake excess rinsing fluid from
cylinder. Do not use a cloth to dry cylinder, as lint from cloth cannot
be kept away from cylinder bore surfaces.
ASSEMBLY
NOTE:
Before installation, wash each part in specified brake fluid.
1) Apply brake fluid to inside of piston assembly and cylinder body.
2) Install piston assembly into cylinder.
3) With piston pushed down, install circlip as shown.
And install boot.

7D-2 TRANSFER
DIAGNOSIS
DIAGNOSIS TABLE
Before attempting to repair the transfer or related components for any reason other than mechanical failure, the
condition and probable causes should be identified.
Transfer failures are revealed by shifting difficulties such as excessive shifting effort, gear clash, or gear grinding.
When any of these conditions occur, the following inspections should be made before disassembling the transfer.
1) Check transfer oil level for insufficient or incorrect oil. Refer to ªTransfer and Differential Oil Inspection and
Changeº in SECTION 0B ªMAINTENANCE AND LUBRICATIONº.
2) Check transfer mountings for wear or looseness.
3) Check gearshift control lever for distortion or excessive wear.
After performing the above inspections, refer to following diagnosis table.

DIFFERENTIAL (FRONT) 7E-1
The differential assembly using a hypoid bevel pinion
and gear is installed to the front axle.
4WD control system controls drive force to be trans-
mitted to front axles or not. The reduction ratio varies
depending on transmission or engine type.The differential assembly is decisive in that the drive
power is concentrated there. Therefore, use of genu-
ine parts and specified torque is compulsory. Further,
because of sliding tooth meshing with high pressure
between bevel pinion and gear, it is mandatory to lu-
bricate them by hypoid gear oil.
