Hydraulic Flow Test
• When using flowmeter other than KUBOTA specified
flowmeter, be sure to use the instructions with the
flowmeter.
• Do not close the flowmeter 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 other 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 engine of 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 min
-1
(rpm).
7. 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. 50 °C (122 °F).
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.
