Vehicle Systems Testing And Adjusting

Steering System Pressure Check

If the steering system does not work correctly, check

the hydraulic tank for the correct oil level and the

hoses and connections for leakage. If all these items

are correct, use the Pressure Gauge Kit to check the

steering hydraulic system and its relief pressure

setting.

Hydraulic pressure can cause personal injury.

Before any steering system hydraulic lines or

components are disconnected, make sure all

hydraulic pressure is released in the steering sys-

tem. Move the steer wheels to the left and right

and then to the straight forward direction.

Check steering system relief pressure as follows:

1. Turn the motor off.

2. Remove plug from elbow(1)

Install pressure-checking adapter(4) and connect

pressure-tube (5) and pressure gage (6). Pressure

gage(6) has a range of 2800 kpa (4000psi).

3. Move the seat to the normal position for operation,

turn the key switch to the ON position and activate

the hydraulic controls until the oil is at a tempera-

ture for normal operation.

4. Turn the steer wheels to the left or right against

the stops and make a note of the indication on the

pressure gauge.

5. The indication on the pressure gauge must be the

priority valve relief setting of 8000 L 350 kPa

(1160 L 50 psi). If the indication is correct and a

problem exists, then there is possibly a mechani-

cal failure in the steering system.

6. If the indication is not correct, then there is steer-

ing hydraulic failure in the components.
