4H-Lock (4Wd High Center Differential Lock) Position - Suzuki GRAND VITARA JB416 Service Manual

4H-lock (4WD High Center Differential Lock) Position

When 4H-lock 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 differential lock shift fork in the
arrow direction "B", and the differential lock clutch sleeve also moves in the arrow direction "B".
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.
