FINAL DRIVE
AWD Operation Overview
With the Polaris All Wheel Drive System activated
(AWD selected), the machine operates as a 2 wheel
drive vehicle until the rear wheels lose traction. If the
rear wheels lose traction the front wheel rotational
speed will decrease, causing the front drive axle
speed to exceed front wheel speed. Restricting the
rotation of the drive clutch roller cage (2) (see Elec-
tric Hub Operation) will cause the rollers (3) to climb
the ramps of the cam (5), and become squeezed be-
tween the ramps and the ring in the hub. See Ill. 1.
When the hub clutch assembly, wheel hub, and drive
axle are engaged, the front wheels will drive and
stay engaged until rear wheel traction is regained.
When traction is regained, the front wheels will over-
drive the hub clutch, pushing the clutch rollers (3) to-
ward the lower part of the cam (5), disengaging the
clutch. The rollers are held in place by the spring (4).
See Ill. 2. The tension of this spring is critical to AWD
hub operation. Always use the correct spring (refer
to appropriate parts manual) and use installation
tool PN 2870888.
WARNING
It is important that the front and rear axle drive ratio
and tire size are not changed. Changing this ratio
will cause erratic engagement, which could result in
a loss of vehicle control and serious injury or death.
Electric Hub Engagement (AWD)
When AWD is selected in a forward gear,
current flows through a coil of wire located
in the strut housing, creating a magnetic
field. An armature plate (1) coupled to the
roller cage (2) is attracted to the magnetic
field, and resists rotation, creating drag on
the drive roller cage assembly.
This
causes the roller to climb the ramps of the
cam, engaging the hub.
NOTE:
In reverse
gear the override button must be pushed to
deliver power to the wheel coil. Electric
hub engagement offers an advantage over
mechanical systems. When the AWD but-
ton is switched off, the machine will have
the steering ease of a 2 wheel drive unit;
and with the switch turned on, All wheel
drive will be engaged whenever the rear
wheels lose traction.
