Steel Rear Idlers

Steel rear idlers are standard, providing maximum reliability in the toughest conditions.

Cat Diesel Power

The heart of the Cat Multi Terrain Loader power train is the Caterpillar C2.2 T diesel engine. This rugged, reliable, four cylinder engine offers aggressive performance and a fast torque curve for quick response. It is also a low emission engine and is Interim Tier 4 compliant.

Dual Engine Throttle Controls

The hand and foot throttles allow the operator to match engine speed to the task. The hand throttle is ideal for jobs requiring consistent engine speed - such as cold planing, trenching or snow blowing. The foot throttle lets the operator vary engine speed and minimizes fuel consumption for other tasks such as load and carry, truck loading, grading and dozing.

Anti-Stall Feature

The anti-stall system on the Cat Multi Terrain Loader allows maximum power to the tracks while minimizing engine stalling. The system helps maximize productivity for experienced operators and makes it easier for novice operators to become productive.

Closed-Loop, High Output Hydrostatic System

The dual, closed-loop, axial piston hydrostatic pumps are driven directly off the engine. The pumps provide pressure and flow to two fixed displacement motors that power the final drive motors, driving the tracks. No chains are used.

Cold Starting Aid

Lift Arms

The loader lift arms are purpose-designed to provide a substantially straight load path into the machine and a good viewing area to the work tool and sides of the machine. The lift arms are also designed to handle heavy loads without twisting and bending for exceptional reliability.

Spherical Bearing

The spherical bearing distributes the load from the lift arm into the frame by allowing the pin to rotate and pivot within the bore, reducing the chance of developing fatigue cracks in the arms.

Power and Reliability

Maximum power and reliability are built into the Cat Multi Terrain Loader hydraulic system. In addition to providing power to drive the tracks, this system also provides the loader lift and tilt functions, powers the auxiliary circuit to drive work tools and drives the engine cooling fan.

Hydraulic Pumps

The hydraulic pumps are driven off the engine for maximum hydraulic performance and reliability - no belts are used. Pumps are fixed-displacement and provide 60 L/min (15.6 gal/min)at high idle. Maximum system pressure for the loader and auxiliary circuit is 23 000 kPa (3,335 psi). Two fixed displacement gear pumps provide flow and pressure for the high flow loader and auxiliary circuit at 100 L/min (26 gal/min) at high idle. Control of the loader lift and tilt functions is by hydraulically-operated joystick controls for low effort and precise operation.

Auxiliary Hydraulics

Standard auxiliary hydraulics to power work tools is available through quick connect hydraulic couplings that are rigidly mounted to the loader arm. The Caterpillar line of XT™ ES and ToughGuard™ hoses as well as O-ring face seals help assure a leak-free system.

Reliability and Cleanliness

Hydraulic system reliability and cleanliness are improved by using single components in place of multiple components, such as the monoblock hydraulic valve and monoblock pumps. Fewer leak points improve reliability and result in a cleaner machine. In addition, hydraulic oil flows through a 5-micron spin-on filter. A filter restriction indicator is located at the operator station. A 74-micron screen in the hydraulic tank prevents larger debris from entering the system and causing damage to the hydraulic components.

Hydraulic Oil Cooler

A high-efficiency hydraulic oil cooler lets the Cat Multi Terrain Loader work longer and harder in higher ambient temperatures, even when using continuous high flow work tools. The high capacity hydraulic oil reservoir also helps keep operating temperatures lower.

Main Frame

The MTL main frame consists of two fully welded, heavy duty structures, the upper frame and lower frame. Weld bosses and links are used throughout the frames and provide chafe-free attachment points for hydraulic tubes, hoses and electrical wiring harnesses to prevent damage.

Lower Main Frame

The lower frame has an internal fuel tank incorporated into the design that is protected from external damage. A removable section has been placed in the floor of the lower frame for cleaning ease.

Upper Main Frame and Lift Arms

Careful attention was given to the placement of components within the frame for favorable weight distribution. The upper frame forms the loader towers and fenders and serves as the attachment point for the rear-tilting cab and tilt-up cooling package. The loader lift arms allow for an excellent viewing area to the work tool. The lift arms also protect the tilt cylinders and associated hydraulic lines and facilitate cab access and egress. The loader arms are designed to handle heavy loads without twisting and bending.

Rear Structures

The rear door, which now opens on the right hand side, and the upper engine enclosure is made of thick gauge steel to protect the back of the Multi Terrain Loader from impact damage and to house the taillights. The bumper is made up of fabricated sections and incorporates two conveniently located tie-down points for transporting the machine. The bumper sits slightly outward from the rear door to protect the body of the machine from dents and scratches to help increase the machine's resale value.

E-Coat Protection

All chassis and cab components are corrosion protected using a process called electro-depositioned paint or “e-coat”. This method is used throughout the automotive industry as a way of providing superior rust prevention and long life. An acrylic topcoat is then applied before the components are assembled on the line for additional protection and durability.

Quick Coupler

Work tools can be changed quickly and easily with the Cat Multi Terrain Loader's quick coupler system. The universal coupler interface features:
• Low profile side plate designed for optimum match to work tools and minimal material packing
• Opposing wedges ensure a tight tool fit, even after years of use
• Rugged design and large contact area absorbs loads and minimizes stress
• Vertical pins are chrome plated and lubricated for smooth engagement and prevention of corrosion
• Coupler allows excellent visibility to work tools and unobstructed entry and exit to the cab
The standard quick coupler features manual engagement and disengagement of work tools using two high leverage handles. An optional hydraulic quick coupler is also available and allows engagement and disengagement of work tools without the operator needing to exit the machine. Control of the coupler by use of a rocker switch inside the cab makes work tool changes quicker and easier.
