Procedure for Steering Control Valve and Steering Cylinder Test: 1. Make sure hydraulic oil is at normal operating temperature by operating the machine for approximately 10 minutes. 2. Perform the Steering Pump Relief Pressure and Steering Pump Flow tests to make sure that pump and relief valve are functioning correctly. NOTE: This steering test procedure will be affected by incorrect tire pressure, binding of the hydraulic steering cylinder, excessive weight on the vehicle, and/or binding of the steering assembly (e.g. wheel spindles, tie rods, steering pivot). Make sure that these items are checked before proceeding with any hydraulic testing procedure. 3. Drive machine slowly in a figure eight on a flat level surface. A. There should be no shaking or vibration in the steering wheel or front wheels. B. Steering wheel movements should be followed immediately by a corresponding front wheel movement without the steering wheel continuing to turn. 4. Stop machine with the engine running. Turn steering wheel with small quick movements in both directions. Let go of the steering wheel after each movement. A. The steering must immediately return to the neutral position. B. The steering wheel or front wheels should not continue to turn. 5. If either of these performance tests indicate a steering problem, determine if the steering cylinder is faulty using the following procedure. A. Park machine on a level surface with the spray system turned off. B. Turn the steering wheel all the way to the right (clockwise) so the steering cylinder rod is fully extended. C. Turn engine off and engage the parking brake. D. Read Pre<strong>caution</strong>s for Hydraulic Testing. E. Remove hydraulic hose from the fitting on the rod end of the steering cylinder. Plug the end of the hose. WARNING Keep body and hands away from disconnected hose and fitting that might eject hydraulic fluid under high pressure. Use paper or cardboard, not hands, to search for leaks. Hydraulic fluid escaping under pressure can have sufficient force to penetrate the skin and cause serious injury. If fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury. Gangrene may result from such an injury. IMPORTANT: Do not turn steering wheel to the left (counterclockwise) as system damage may occur. F. With the engine off, continue turning the steering wheel to the right (clockwise) with the steering cylinder fully extended. Observe the open fitting on the steering cylinder as the wheel is turned. If oil comes out of the fitting while turning the steering wheel to the right, the steering cylinder has internal leakage and must be repaired or replaced. G. Remove plug from the hydraulic hose. Reconnect hose to the steering cylinder. 6. If steering problem exists and the steering cylinder tested acceptably, steering control valve requires service (see Steering Control Valve and Steering Control Valve Service).
