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.

Make sure to use wood block to prevent contact which
may occur between dash panel and CMP sensor case
(G16), CMP sensor (J20) or intake manifold (H25), and fan
and shroud.
IN CABIN
1) Remove console box.
2) Remove shift lever of transmission and transfer.
ON LIFT
1) Drain transfer oil.

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.

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.
