Steering Cylinder Internal Leakage Test
1. Engage the parking brake, and lower the cutting unit
to the floor.
2. Turn the steering wheel all the way to the left (coun-
terclockwise) on a 2WD machine or to the right (clock-
wise) on a 4WD machine, 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. 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
turning the steering wheel to the left, the steering cylin-
der has internal leakage and must be repaired or re-
placed.
NOTE: DO NOT turn the steering wheel to the right
(clockwise) or the steering valve will meter oil out the
disconnected hydraulic hose.
