Differential Operation

The INT'L tra nsmission h as two traction operational
modes: Differential Lock and Differential Unlock. Locking
the rear differential is beneficial in low traction and rough
terrain co nditions. Unlo cking the rea r differential makes
maneuvering easier and minimizes damage to terrain.

Differential - Lock
Differential - Unlock
When "Differential-Unlock" is selected, the rear differential
becomes unlocked for tighter turns. An electrical solenoid
mounted in the rear portion of the gearcase actuates the
shift fork. The solenoid plunger extends out to move the
fork and slides the engagement dog away from the side
gear that is part of the planetary differential assembly. This
unlocks the rear differential. The rear drive shafts are now
dependent on the differential allowing for tighter turns.

When switch position is set
to "Unlock", the solenoid is
powered and the plunger
extends to disengage the
side gear and unlock
the differential.
When "Dif ferential-Lock" is selected, po wer is re moved
from the electrical solenoid allowing the solenoid plunger
to retract. Spring tensio n moves the shif t fo rk back into
place and mates the engagement dog to the side gear that
is part of the planetary differential assembly. This locks the
rear differential as a solid rear axle, increasing traction.
When switch position is set
to "Lock", power is removed
from the solenoid and spring
tension retracts the plunger
to engage the clutch gear
and lock the differential.
