The steering system consists of the following components:
• The wheel motor housings have pivots on the top and bottom, and are mechanically linked
together via a tie-rod.
• Steering is accomplished hydraulically by using two (2) double-acting cylinders, and a 4-way
3-position solenoid-operated, hydraulic directional control cartridge valve.
• Maximum steering pressure is limited by the steering relief valve (refer to Relief Pressure
Adjustment Procedure).
