Before disconnecting or performing any work on the hydraulic
system, all pressure in the system must be relieved. See

3. Disconnect the hose connection on the reel gear pump leading to the
steering control valve.
4. Install the tester in series with reel drive pump and the disconnected hose
leading to the steering control valve.
5. Make sure that the flow control valve on the tester is fully open.
6. Sit in the operator's seat and start the engine. Move the throttle to full speed
(2650 ±50 RPM).
7. Make sure that the hydraulic fluid is at normal operating temperature by
operating the machine for approximately 10 minutes.
8. Verify with a phototach that the pump speed is approximately 3100 RPM.
9. Verify pump flow at No Load as follows:
Record tester pressure and flow readings at no load. Unrestricted pump
output should be approximately 14.7 LPM (3.9 GPM).
Do not close tester valve fully when performing this test. In this test,
the hydraulic tester is positioned before the manifold relief valve.
Pump damage can occur if the fluid flow is fully restricted by fully
closing the tester flow control valve.
