[2]  HYDRAULIC PUMP (FOR THREE POINT HITCH)

(1)  Pump Test Using Flow-meter

Preparation

1. Pull down the knob and open the bonnet.

2. Remove the side skirt R.H..

3. Remove the main delivery pipe (1).

(When reassembling)

• Install the copper washers firmly.

Hydraulic Flow Test

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. Install  the  pump  adaptor  (see  page  G-68)  with  O-ring  to  the

pump discharge port.

2. Connect the hydraulic test hose to the adaptor 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.

14.7 MPa (150 kgf/cm

2

, 2133 psi). Hold in this condition until oil

temperature reached 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 (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.
