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.
