Hydraulic Flow Test
IMPORTANT
■
• 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. Remove the delivery pipe (1).
2. Install the adaptor (4) (See page G-72) the pump discharge port
and regulator valve inlet port.
3. Connect the hydraulic test hose (5) to the adaptor at hydraulic
pump (3) and flowmeter inlet port.
4. Connect the other hydraulic test hose (6) to the flowmeter outlet
and adaptor (4) (see page G-72) at regulator valve (2).
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 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, next page.)
10.Read and note the pump delivery at no pressure.
11.Slowly close the loading valve to increase rated pressure. (Refer
to Condition, next page.) 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.
