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.

Advanced Hydraulic System



The hydraulic system has builtin reliability and provides exceptional lift, breakout and auxiliary power to work tools.

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 fixeddisplacement and provide 60 Lmin 15.6 galminat 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 Lmin 26 galmin at high idle. Control of the loader lift and tilt functions is by hydraulicallyoperated 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 Oring face seals help assure a leakfree 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 5micron spinon filter. A filter restriction indicator is located at the operator station. A 74micron screen in the hydraulic tank prevents larger debris from entering the system and causing damage to the hydraulic components.
