Hydraulic Flow Test (for Power Steering)

IMPORTANT

• When using a flowmeter other than KUBOTA specified

flowmeter, be sure to use the instructions with that
flowmeter.

• Do not close the flowmeter loading valve completely,

before testing, because it has no relief valve.

1. Loosen the delivery pipe and install the adaptor 

52

 to the pump

discharge port.

2. Connect the hydraulic test hose to the adaptor 

52

 and flowmeter

inlet port.

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

port and to transmission fluid filling plug hole.

4. Open  the  flowmeter  loading  valve  completely.  (Turn

counterclockwise.)

5. Start the engine and set the engine speed at 2000 to 2200 min

-1

(rpm).

6. Slowly close the loading valve to generate pressure approx. 9.8

MPa  (100  kgf/cm

2

,  1422  psi).  Hold  in  this  condition  until  oil

temperature reaches approx. 40 °C (104 °F).

7. Open the loading valve completely.

8. Refer to 

"Condition"

 below to set the engine speed.

9. Read and note the pump delivery at no pressure.

10. Slowly  close  the  loading  valve  to  increase  pressure  (Rated

pressure).  As  the  load  is  increased,  engine  speed  drops,

therefore, reset the engine speed.

11. Read and note the pump delivery at rated pressure.

12. Open the loading valve completely and stop the engine.

13. If the pump delivery does not reach the allowable limit, check

the pump suction line, oil filter or hydraulic pump.
