AWD OPERATION OVERVIEW
Ramps
Hub
Cage (2)
Roller (3)
Axle
Cam (5)
With the Polaris All Wheel Drive System activated
(A WD 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
rotationof thedriveclutchrollercage(2)(see Electric
Hub Operation) will cause the rollers (3) to climb the
rampsofthecam(5),andbecome squeezedbetween
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
tractionisregained, the front wheels will overdrivethe
hub clutch, pushing the clutch rollers (3) toward the
lowerpart of thecam (5), disengaging theclutch. 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 the
Hilliard Clutch
Garter Spring Installation Tool (PN 2870888).
WARNING
It is important that the front and rear axle drive ratio
and tire sizeare not changed. Changing this ratiowill
causeerraticengagement,whichcouldresultinaloss
of vehicle control and serious injury or death.

Ill. 2
When AWD is selected in a forward gear , current
flowsthroughacoilofwirelocatedinthestruthousing,
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 theroller
to climb the ramps of the cam, engaging the hub.
