21. Install lock washer and lock screw in the following
manner.
Turn the side with larger diameter of the tapered
bore to the vehicle outer side, and attach the
washer.
If the bolt holes in the lock plate are not aligned with
the corresponding holes in the nut, reverse the lock
plate.
If the bolt holes are still out of alignment, trun in the
nut just enough to obtain alignment.
Screw is to be fastened tightly so its head may
come lower than the surface of the washer.

TRANSFER CASE (STANDARD TYPE)
4D1–7
A/T, WO/Shift On The Fly, WO/4WD Switch, model
A07RW055
The transfer case is used to provide a means of providing
power flow to the front axle. The transfer case also
provides a means of disconnecting the front axle,
providing better fuel economy and quieter operation when
the vehicle is driven on improved roads where four wheel
drive is not required. In addition, the transfer case
provides an additional gear reduction when placed in low
range, which is useful when difficult off–road conditions
are encountered.
A floor mounted shift lever is used to select the high–low
range. When four wheel drive switch has been turned on,
the four wheel drive indicator light is designed to come on
when the front axle has been engaged.
