STEERING AND BRAKE SYSTEM

1. Steer Cylinders

. A cylinder is mounted at both ends of each axle and controlled by the steering wheel.

2. Steering Control Valve

. Connected directly to the steering wheel and located behind the instrument access panel. Con-

trols the steering function by directing the flow of hydraulic fluid to the cylinders.

3. Steer Select Valve

. Externally mounted under the cab. Allows the selection of two wheel, four wheel, or crab steering

through the steer select control, a three-position switch.

4. Brake Control Valve

. Located under the cab. Provides a priority flow to the brake system. Excess flow is directed by the

priority valve to the frame tilt system.

5. Service Brakes

. Dry disc, caliper-type brakes are mounted on all four wheels. The service brakes are hydraulically

actuated by pressing the brake or transmission disconnect pedals. An accumulator in the braking system enables a

limited number of stops without engine power.

6. Parking Brake

. A mechanically actuated drum brake is mounted on the front axle input shaft. A lever in the cab engages

and disengages the parking brake.
