(5) Power Steering Hydraulic Pump

Hydraulic Flow Test

A

When using a flowmeter other than KUBOTA specified
flowmeter (Code No. 07916-52792), be sure to use the
instructions with the flowmeter.

A

Do not close the flowmter loading valve completely,
before testing, because it has no relief valve.

1. Disconnect the delivery pipe which is connected from

hydraulic pump to steering controller.

2. Install the adaptor 53 and 54 to the pump discharge port.

[Adaptor 53 and 54 are included in adaptor set (Code No.
07916-54301).]

3. Connect the hydraulic test hose to the adaptor 53 and

flowmeter inlet port.

4. Connect the other hydraulic test hose to the flowmeter outlet

and put the end of the hose into the transmission oil port.

5. Open the flowmeter loading valve completely. (Turn

counterclockwise.)

6. Start the engine and set the engine speed at 2000 to 2200

(rpm).

7. Slowly close the loading valve to generate pressure approx.

9.8 MPa (100

, 1422 psi). Hold in this condition until oil

temperature reaches approx. 50

(122

).

8. Open the loading valve completely.
9. Set the engine speed. (Refer to condition.)
10. Read and note the pump delivery at no pressure.
11. Slowly close the loading valve to increase rated pressure.

(Refer to condition.) As the load is increased, engine speed
drops, therefore, reset the engine speed.

12. Read and note the pump delivery at rated pressure.
13. Open the loading valve completely and stop the engine.
14. If the pump delivery does not reach the allowable limit, check

the pump suction line, oil filter or hydraulic pump.
