(31) Gear Pump (Steering Pilot). (32) Breaker Relief Valve. (35) Hydraulic Tank (Steering and Brake).The steering hydraulic system is made up of two basic circuits:
Oil filter and oil cooler circuit
Pilot circuit
High pressure circuit
Secondary steering circuit (if equipped)The secondary steering system is optional. Some machines may also include this circuit.The main components of the oil filter circuit and the oil cooler circuit include the following items: oil cooler (16), pilot relief valve (19), steering pilot oil filter (28),
