Front Axle. The Caterpillar

sealed

spindle keeps the bearings free from
contaminants and lubricated in a
light-weight oil (1). This durable,
low-maintenance design reduces your
owning and operating costs. Two tapered
roller bearings (2) support the wheel
spindle. The Cat “Live Spindle” design
places the larger tapered roller bearing
outboard where the load is greater,
extending bearing life.

Gear Selection. Eight forward and
six reverse gears give the operator a
wide operating range. The specifically
designed range of gears ensures
maximum productivity in all
earthmoving applications.

Programmable Autoshift. The operator
can easily customize various shift
parameters through Cat Messenger
to match the specific application
requirement. This feature automatically
shifts the transmission at optimal points
so the operator can focus on the work,
improving safety, productivity and
ease of operation.

Inching Pedal. Allows precise control
of machine movements in any gear
with low pedal effort and excellent
modulation, critical in close-quarter
work or finish grading.

Hydraulic Brakes. The oil bathed,
multi-disc service brakes are
hydraulically actuated (1), providing
smooth predictable braking and lower
operating costs. With brakes located at
each tandem wheel, the 120M offers
the largest total brake surface area in
the industry (2), delivering dependable
stopping power and longer brake life.

Brake Serviceability and Reliability.
An easily accessible brake wear
indicator/compensator system (3)
maintains consistent brake performance
and indicates brake wear without
disassembly. This system cuts service
time and extends brake service life.

Parking Brake. The spring-applied,
hydraulically released multi-disc
parking brake is a sealed, oil-cooled
design extending component life and
reducing the need for service. The parking
brake is integrated into the Operator
Presence System to prevent unintended
machine movement.
