Steering Servo Valve Testing
This section explores the testing of the steering servo valve. The pump deadband signifies the pressure needed to counteract the control springs and initiate the pump upstroke. Adjustments can be made using the neutral adjusting screw to balance pressures in varying directions. The test verifies the positioning of the servo valve for optimal steering.

Conduct this diagnostic test under the following conditions:
u2022 If the steering pump upstrokes while the transmission control lever is in the PARK position.
u2022 If belts move while the machine is elevated and the transmission control lever is in PARK.

Electrical issues may be indicated by:
u2022 Steering pump upstrokes only when the transmission control lever is in NEUTRAL.
u2022 Belts moving when the machine is raised and the transmission control lever is in NEUTRAL.

It may be necessary to calibrate the steering wheel as a preliminary step.
