Section 06 DRIVE SYSTEM
Subsection 01 (FRONT DRIVE)
GENERAL
The procedure explained below is the same for
the RH and LH sides unless otherwise instructed.
SYSTEM DESCRIPTION
The Visco-Lok ® system constantly monitors front
wheel speed and, if it detects one wheel spinning
faster than its mate, it progressively sends more
power to the wheel with the better traction.
The Visco-Lok system is comprised of two princi-
pal components, a shear pump and the controlled
multi-plate clutch.
A unique feature of the shear pump is that it
is self-contained and independent. It does not
require an external source of hydraulic fluid. The
self-contained viscous shear pump generates a
pressure proportional to wheel speed differential
- meaning the difference in rotational speed be-
tween the two wheels. This pressure engages
the friction clutch via a piston to transmit the
torque.
In the event of a failure, the Visco-Lok carrier/ring
gear and pinion gear will have to be replaced.
NOTE: The Visco-Lok shear pump is not service-
able. If the pump is disassembled, the viscous
fluid contained inside will be lost and it cannot be
replaced.

TYPICAL
1. Cotter pin
2. Castellated nut
3. Belleville washer
Remove wheel hub.
Wheel Hub Inspection
Check wheel hub for cracks or other damages.
Check inner splines for wear or other damages.
If any damage is detected on wheel hub, replace
it with a new one.
Wheel Hub Installation
The installation is the reverse of the removal pro-
cedure. However, pay attention to the following.
Install Belleville washer with its convex side out-
wards.
Tighten castellated nut to specification.
Castellated nut
NOTE: Tighten further castellated nut if required
to align grooves with drive shaft hole.
BRAKES
Install a NEW cotter pin.
