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.

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.

Before performing the trouble diagnosis, check that the transfer and front differential are in good condition and
there is no air leakage from air hoses and the actuator. Refer to ªON-VEHICLE SERVICEº in this section for air
leakage.
[NOTES ON SYSTEM CIRCUIT INSPECTION]
Be sure to read ªPrecautions for Electrical Circuit Serviceº in Section 0A before circuit inspection and observe
what is written there.
For system circuit, refer to the figure of ªGENERAL DESCRIPTIONº in this section.
For terminal arrangement, refer to ª4WD Control Circuit Inspectionº in this section.

MAINTENANCE SERVICE
NOTE:
When having driven through water, check immediately if wa-
ter has entered (if so, oil is cloudy). Water mixed oil must be
changed at once.
Whenever vehicle is hoisted for any other service work than
oil change, also be sure to check for oil leakage and status
of breather hoses.
Gear Oil Change
NOTE:
Hypoid gear oil must be used for differential.
It is highly recommended to use SAE 80W ± 90 viscosity.
1) Before oil change or inspection, be sure to stop engine and lift
up vehicle horizontally.
2) Check oil level and existence of leakage. If leakage is found, cor-
rect its cause.
3) Drain old oil and pour proper amount of gear oil as specified be-
low (roughly up to level hole).
4) Apply sealant to thread of drain plug (b) and torque plugs to
specification.
