How does Polaris on demand 4X4 work?
When in AWD on any Polaris vehicle, the front gearcase automatically will engage any time the rear wheels lose traction. When the rear wheels regain traction, the front gearcase automatically will disengage. There is no limit to the length of time the vehicle may remain in AWD.
How does a Hilliard clutch work?
The Hilliard Front Drive System is an electro-mechanically activated bidirectional overrunning clutch. When 12 volts of power are sent via the 4WD switch, the unit is activated to engage both front wheels instantaneously, whenever the rear wheels lose traction.
How does a Polaris front differential work?
With the rollers wedged, the ring gear then transfers power to the hubs, axles, and wheels, thus providing four-wheel drive. The rollers want to pop out of the sprague. When they get wedged in a peak, they squeeze the axle hubs with enough force to drive the front wheels.
How does Polaris front differential work?
The front diff is geared lower than the transmission, which means the front axles have more torque and turn slower than the rear axles. If you’re driving on dry, flat ground with four-wheel drive engaged, the ring gear turns slower than the front axles, which are rolling the same speed as the rear axles.
What is the ECM on Polaris ATV?
Polaris determined your ATV was assembled with a possibly defective Electronic Control Module (ECM). Polaris has determined the recall defect could cause the ECM to fail and overheat. If this were to occur, excessive heat could cause a fire, possibly resulting in severe injury or death.
How does a Hilliard differential work?
Front Drive System (Differential) The Hilliard Front Drive System is an electro-mechanically activated bidirectional overrunning clutch. When 12 volts of power are sent via the 4WD switch, the unit is activated to engage both front wheels instantaneously, whenever the rear wheels lose traction.
What is differential lock on a ATV?
The diff lock forces all wheels to spin at the same speed, regardless of traction. This is helpful if you encounter difficult terrain and one or more wheels leave the ground, as full power remains on the other wheels ensuring you are still moving in the direction of travel.
What is ADC fluid for Polaris?
PURE POLARIS OIL ADC FLUID. ADC FLUID : Designed specifically for rapid reaction of the ADC hydraulic system.
Where is the fuse box located on a Polaris four wheeler?

How do you test a front differential?
With the front tires off the ground when you turn one front wheel forward the other should turn backward. If it doesnt The front axle has not engaged. If it does, Have a friend hold one side from moving while you spin the other side.
What is the difference between diff lock and 4X4?
Cars only have one differential, but 4X4 vehicles can have up to three differentials – front, centre and rear. A differential lock secures this differential in place, making all the wheels on the axle move at the same speed. This pushes equal power through to all wheels, which is needed when handling difficult terrain.
