1. OUTLINE

The steering system of this machine consists of a variable displacement piston pump supplying a 
load sensing steering system and an closed center loader system.

The components of the steering system are :

·

Steering pump 

·

Steering valve (EHPS)

·

Steering unit

·

Accumulators

·

Steering cylinders

The steering pump, the first pump of main pump, draws hydraulic oil from the hydraulic tank.
Outlet flow from the pump flows to the priority valve of steering valve. The priority valve of steering 
valve preferentially supplies flow, on demand, to the steering unit. When the machine is steered, the 
steering unit routes flow to the steering cylinders to articulate the machine.

When the machine is not being steered, or if pump flow is greater than steering flow, the priority valve 
supplies flow to the loader system.

That is, output flow from the steering pump enters into the main control valve for the operation of the 
attachment.
