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.
