Testing

Note: For testing the gear pump section that supplies

the steering circuit, see Test No. 8 in Chapter 4−Hydrau-

lic System of this manual.

Steering Cylinder Internal Leakage Test

1. Engage the parking brake, and lower the cutting

units to the floor.

2. Turn the steering wheel all the way to the left (coun-

terclockwise) so the steering cylinder rod is extended all

the way.

3. Turn the engine OFF

4. Disconnect the hydraulic hose from the fitting on the

rod end of the cylinder (Fig. 8). Put a plug in the end of

the hose to prevent contamination.

5. With the engine OFF, continue turning the steering

wheel to the left (counterclockwise) with the cylinder rod

completely extended and observe the open fitting on the

steering cylinder. If oil comes out of the fitting while turn-

ing the steering wheel to the left, the steering cylinder

has internal leakage and must be repaired or replaced.

Note: DO NOT turn the steering wheel to the right

(clockwise) or the steering valve will meter oil out the dis-

connected hydraulic hose.
