Description

Volvo BM L70C is a four-wheel drive loader with articulated steering.

The engine is a 6-cylinder, turbocharged diesel engine type TD61GD or TD63KDE (low-emission engine).

The transmission is hydro-mechanical, where all gears are in constant mesh. The type designation is HT90.

Between engine and transmission there is a single stage hydraulic torque converter.

Front and rear axles have fully floating drive shafts with planetary gears in the wheel hubs.

The service brakes of the machine are disc brakes running in oil and integrated with the respective planetary gear hubs. The drum brake type parking brake is fitted on the front axle.

The machine is provided with two load-sensing variable hydraulic pumps connected in parallel which, via a central valve, supply steering, brakes, servo and working hydraulics with oil.

For further description of function and components, see the respective manual section.
