TRANSFER CASE, AUTOMATIC HUB LOCK & LIMITED SLIP DIFFERENTIAL

Transfer Case and Transfer Case Selector Electric Switch

(If fitted)
On four wheel drive vehicles transfer case is fitted after the
gear box for driving front live axle along with rear axle.
The following 3 selector positions are provided on the knob.
2H - Only two rear wheels are driven and transfer case
operates at 1:1 ratio.
4H - All four wheels are driven and transfer case operates
at 1:1 ratio.
4L - All four wheels are driven and transfer case operates
at 2.48:1 speed reduction ratio.
4X4 Selector Switch
For driving in 2H mode keep the selector knob in 2H position.

Automatic Hub Locks

While driving in 2H mode this mechanism on the front axle
hub allows the hub to free wheel. This avoids the unnecessary
spinning of front drive components and results in fuel saving,
reduced noise and longer component life.
As soon as 4H or 4L mode is selected the hub gets
automatically connected to front drive line to increase the
traction.

Limited Slip Differential

(Standard on 4x4 and optional on others)
A standard differential delivers torque equally to each wheel.
In case one wheel loses traction and begins to spin, the
differential distributes the rotary speed unequally but with
same torque. This can cause the wheel with good traction to
slow down or stop while the wheel which lost traction rotates
with increased speed. Such a situation can prevent the vehicle
from moving.
The limited slip differential provided in the rear axle takes
care of such situations. The clutch lock arrangement provided
internally, ensures that in case one wheel loses traction and
begins to slip, a locking action takes place which prevents
differential action and both wheels turn at the same speed.
