Main components of loader:

1, engine.

2. Drive: transmission shaft, main differential and wheel side reducer.

3. Working hydraulic oil circuit, hydraulic oil tank, working pump, multi-way valve, lifting oil cylinder and tilting oil cylinder.

4. Travel oil circuit: transmission oil pan, travel pump, one-way torque converter, one-way gear valve and transmission clutch.

5. Steering oil circuit: oil tank, steering pump, steering gear with steady flow valve (or priority valve) and steering cylinder. 7. There are two types of gearboxes: integrated (planetary) and split (fixed shaft).

6. There are three pumps on the torque converter. The working pump (supplying lifting and tipping pressure oil) and the variable speed pump (supplying steering pressure oil) are also called walking pumps (supplying torque converter and gearbox pressure oil). Some models of steering pump are also equipped with a pilot pump (which provides pilot pressure oil for the control valve).
