FINAL DRIVE

                ALL WHEEL DRIVE OPERATION
                The AWD switch may be turned on or off while the
                vehicle is moving, however, AWD will not enable until the
                engine RPM drops below 3100. Once the AWD is
                enabled, it remains enabled until the switch is turned off.
                Engage the AWD switch before getting into conditions
                where the front wheel drive may be needed. If the rear
                wheels are spinning, release the throttle before switching
                to AWD.
                                   CAUTION
                  Switching to AWD while the rear wheels are spinning
                  may cause severe drive shaft and gearcase damage.
                   Always switch to AWD while the rear wheels have
                               traction or are at rest.

                With the AWD switch off, the vehicle drives through the  AWD Disengagement: Once the rear wheels regain
                rear wheels only (2 wheel drive). When the AWD is    traction, the front wheels will return to the “over-running”
                enabled, the front drive acts as an on-demand AWD    condition. The vehicle is now back to rear wheel drive
                system. This means, the front drive will engage once the  until the next loss of rear wheel traction occurs.
                rear wheels have lost traction, and will remain engaged  Torsion Spring Operation: The torsion spring acts as a
                until the torque requirement goes away (i.e. rear wheels  return mechanism to help disengage the coupling of the
                regain traction).                                    output hubs and ring gear by creating an “over-running”
                                                                     condition for the rollers upon disengagement.
                                   CAUTION
                   If the rear wheels are spinning, release the throttle
                          before turning the AWD switch on.
                   If AWD is engaged while the wheels are spinning,
                  severe drive shaft and front gearcase damage could
                                      result.

                AWD Engagement: When the AWD switch is activated,
                the AWD coil is powered by a 12 Vdc input which creates
                a magnetic field. This magnetic field attracts an armature
                plate that is keyed to the roll cage. When the ring gear
                and roll cage are spinning (vehicle is moving), the
                energized coil and armature plate will apply drag to the
                roll cage that indexes the rollers inside the ring gear to an
                engagement position. While in the engagement position,
                the front drive will be in an “over-running” condition (not
                engaged), until the rear wheels lose traction. Once the
                rear wheels begin to lose traction, the front drive will
                engage by coupling the output hubs to the ring gear via
                the rollers. The front drive will remain engaged until the
                torque requirement goes away (i. e. rear wheels regain
                traction).
