Test Procedure
Groundsmaster ® 3280-D/3320
05138SL Rev B
The steering cylinder internal leakage test should be performed if a steering
problem is identified. This test will determine if the steering cylinder is damaged.
Note: Steering circuit operation will be affected by rear tire pressure, steering
cylinder binding, extra weight on the vehicle, and/or binding of rear axle steering
components. Ensure that these items are checked before proceeding with
steering cylinder internal leakage test.
1. Ensure that the hydraulic fluid is at normal operating temperature.
2. Park machine on a level surface with the cutting deck (or implement) lowered
and PTO switch off. Ensure that the engine is shut off. Set the parking brake.
3. Read all Warning, Cautions, and precautions listed at the beginning of this
section.
Before opening hydraulic system, operate all hydraulic controls to
relieve system pressure and avoid injury from pressurized hydraulic
fluid.
4. Turn the steering wheel for a right turn (clockwise) so the steering cylinder
rod is fully extended.
5. Remove hydraulic hose from the fitting on the rod end of the steering cylinder.
Plug the end of the hose.
