DISASSEMBLY AND ASSEMBLY CLUTCH
MASTER CYLINDER
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.

TRANSFER 7D-1
The aluminum transfer case directly connected to the
back of the transmission contains the input gear,
countershaft & gear, output rear shaft, output low gear
and output front shaft (for front drive) connected by
way of the hyvo-chain.
The transfer has such a selective mechanism as to
enable the shift control lever to make selection of high
speed (direct connection with transmission output:
main shaft), low speed (speed reduction by input
gear, counter gear and output low gear) or neutral by
way of the reduction sleeve located between input
gear and output low gear, and selection of two-wheel-
drive (high speed only) or four-wheel-drive (high or
low speed) by way of the front drive clutch sleeve lo-cated at the center of the output rear shaft. Also, with
a synchronizer installed to the front drive clutch, it is
possible to change the drive mode between 2WD
(high speed only) and 4WD (high speed only) even
while running.
The front drive shift fork has an auxiliary spring to
make a smooth shift from 4H to 2H possible.
The case has an oil gutter and a plate at synchronizer
to provide proper lubrication even under the strict
conditions of use.
WARNING:
For towing the vehicle for the purpose of repair or
the like, follow the towing instructions in OWN-
ER'S MANUAL.

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.
