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.
