Including engine, torque converter, gearbox, front and rear drive axles, referred to as four major parts
1. Engine
2. There are three pumps on the torque converter, the working pump (supplying pressure oil for lifting and dumping bucket), the steering pump (supplying steering pressure oil), the variable speed pump, also known as the traveling pump (supplying torque converter, transmission pressure oil), some models The steering pump is also equipped with a pilot pump (supplying pilot pressure oil for the control valve)
3.. Working hydraulic oil circuit, hydraulic oil tank, working pump, multi-way valve, lift cylinder and tipper cylinder
4. Traveling oil circuit: transmission oil sump oil, travel pump, all the way into torque converter and one into gear valve, transmission clutch
5. Drive: drive shaft, main differential, wheel reducer
6. Steering oil circuit: fuel tank, steering pump, steady flow valve (or priority valve) steering gear, steering cylinder
7. There are two types of gearboxes: integrated (planetary type) and split (fixed shaft type)
