Standard Features
Transmission
Programmable Top Gear Selection
Allows the operator to manually set the top gear
(3rd -8th) available to match the conditions or to match
the hauling speed of the fleet to specific job-site needs.
Retarder
Power Train – Transmission
Integrated electronics slows the machine to monitor the
power train which reduces stress as well as provides a
better ride to the operator.
Transmission
Electronically controlled Caterpillar ® planetary
powershift transmission with eight forward and one
reverse speed. Tractor gear 1 & 2 operate in converter
drive for increased torque capability during cut and fill
operations. Gears 3-8 operate in direct drive for drive
train efficiency during the haul. All scraper gears operate
in converter drive for increased torque capability during
the cut and fill.
Synchronized Scraper Transmission
The scraper transmission is electronically controlled
by the tractor transmission, synchronizing the scraper
transmission gear selection with that of the tractor
transmission. The scraper transmission cannot be
shifted manually. A neutral/run switch, located in
the cab, allows the operator to disengage the
scraper transmission.
Planetary Design
Provides larger contact area between gears than
countershaft transmission for greater load-carrying
capacity.
Transmission Hold
Allows the operator to maintain converter for increased
drive for the increased rimpull, or hold the current gear
for enhanced control.
The retarder should be used on downgrades to reduce
wear on the service brakes and enhance machine
control. The retarder acts as an internal brake on the
driveline that minimizes the need to apply service brakes.
The operator typically engages the retarder 3 to 4
seconds before the machine begins a downhill grade.
Differential Control
Electronic differential lock helps prevent the drive wheels
from spinning in poor underfoot conditions located in
the cab.
Neutral Coast Inhibitor
Neutral coast inhibitor prevents the transmission from
shifting into neutral if the operator selects neutral
while moving.
Final Drives
Outboard-mounted planetary design final drives
reduce torque loads on other power train components.
Large-capacity, double-row roller bearings and
Caterpillar ® Duo-Cone seals deliver exceptional reliability
in the toughest applications.
Independent Systems
Expanding shoe-type breaks are a cam-operated design
that is air-applied and spring released. The breaking
systems uses independent front and rear circuits with
secondary brakes automatically applied if the service air
pressure drops to 380 kpa (55psi).
Parking Breaks
The push-button operated parking break features a
spring-applied, air released mechanism that operates
the service brakes.

Cushion Hitch
The electronically actuated cushion hitch incorporates a parallelogram-type linkage for exceptional strength
with nitrogen accumulators to deliver a smooth ride for enhanced operator comfort.
Controlled oil flow dampens rebound oscillation
Leveling valve automatically centers piston in cylinder for all loads.
Steel castings are used extensively to eliminate many welding joints and increased strength. Double kingbolt
design withstands high external forces and simplifies installation and removal.
Nitrogen Accumulators
Vertically mounted hydraulic cylinder transfers road shock to nitrogen accumulators. Nitrogen accumulators
absorb and dampen road shock thus preventing these loads from being transmitted to the operator.
Lockout Switch
An operator-selectable lockout switch, located on the joystick, locks all cushion hitch for improved control of the
cutting edge during loading and dumping.

Standard Features-Structures
Elevator Design
Single drive motor provides improved life over original dual motor design—torque oscillation between motors is eliminated.
A high torque hydraulic drive motor turns the elevator at a constant speed under heavy loads. This lets the operator select the
best loading depth without continual adjustment. Leaves the cut smooth for easier, more efficient loading on the next pass.

Standard Features-Structures
Bowl Design
Bowl cutting edge supports a variety of Caterpillar ® Ground-Engaging Tools (GET). Cellular construction
adds strength and dent resistance to bowl sides and floor.
• Rugged J-link design is used to operate the rotating floor. The rotating floor scrapes the side of the bowl
clean without the use of rollers and tracks which can be deformed or bound by falling material.
• Swinging Elevator Mounting System protects flights and cutting edge against sudden shock. Elevator
is free to swing upward to accommodate rocks or other large objects and quickly returns to its original
position to keep loading the bowl corner system.
• Structural tube design in addition to formed plates to increase strength and durability.
• Hydraulic housing and electrical inside cellular wall.
