Suzuki Grand Vitara JB416 / JB420. Manual — part 173
3C-6 Transfer: Motor-Shift Type (Transfer with Shift Actuator)
The driving force from the transmission is transmitted from the transfer input gear to the rear output shaft, as in the
case of 4H position. Also, as the front drive shaft and front drive sprocket bush are engaged via differential lock clutch
sleeve, the driving force from the input gear is locked and transmitted to the rear output shaft.

N (Neutral) Position
When N position is selected from 4H position by turning the transfer switch, the transfer shift control actuator motor
runs and shift cam rotates in the arrow direction “A”. The shift cam shifts the High / Low shift fork in the arrow direction
“B”, and the reduction shift sleeve moves in the arrow direction “B”. Also, the shift cam shifts the differential lock shift
fork in the arrow direction “C”, and the differential lock clutch sleeve also moves in the arrow direction “C”.
The driving force from the transmission is transmitted to the transfer input gear. However, as the reduction shift sleeve
is not engaged with the transfer input gear and low gear, the driving force is not transmitted to the rear output shaft and
front output shaft.

4L-lock (4WD Low Center Differential Lock) Position
When 4L-lock position is selected from 4H-lock position by turning the transfer switch, the transfer shift control
actuator motor runs and shift cam rotates in the arrow direction “A”. The shift cam shifts the High/Low shift fork in the
arrow direction “B”, and the reduction shift sleeve moves in the arrow direction “B”. Also, the shift cam shifts the
differential lock shift fork in the arrow direction “C”, and the differential lock clutch sleeve also moves in the arrow
direction “C”.
The driving force from the transmission is transmitted from the transfer low gear, through the transfer input gear and
transfer counter gear with the speed reduced. At this time, as the center LSD case and transfer low gear are engaged
via reduction shift sleeve, the driving force is transmitted to the rear output shaft.
The driving force of the rear output shaft makes the front output shaft rotate via the differential lock clutch sleeve as in
the case of 4H-lock position.
