REAR GEARCASE (RZR S INT’L)
General Operation
The RZR S INT’L rear gearcase has three traction operational
modes: AWD, Differential Lock, and Differential Unlock.
Locking the rear differential is beneficial in low traction and
rough terrain conditions. Unlocking the rear differential makes
maneuvering easier and minimizes damage to turf and sensitive
terrains.
When “Differential-Unlock” is selected on the switch, the rear
differential becomes unlocked for tighter turns. An electrical
solenoid mounted in the rear gearcase housing actuates the shift
yoke. The solenoid plunger extends out to move the shift yoke
and slides the clutch gear away from the engagement dogs that
are attached to the differential gear assembly. This unlocks the
rear differential.
When “Differential-Lock” is selected on the switch, power is
removed from the electrical solenoid allowing the solenoid
plunger to retract. Spring tension moves the shift yoke back into
place and engages the clutch gear into the engagement dogs that
are attached to the differential gear assembly, locking the rear
differential as a solid rear axle.
