(1) Hydraulic Pump for Three-Point Hitch
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. Disconnect the delivery pipe (3) from hydraulic pump (1) to
hydraulic cylinder (4).
2. Install the adaptor (5) (refer to “8. SPECIAL TOOLS” at “G.
GENERAL” section) to the pump discharge port and hydraulic
cylinder inlet port.
3. Connect the hydraulic test hose (7) to the adaptor (5) (refer to “8.
SPECIAL TOOLS” at “G. GENERAL” section) on the pump and
flowmeter inlet port.
4. Connect the other hydraulic test hose (8) to the flowmeter outlet
port and hydraulic cylinder inlet 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 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.
Condition
• Engine speed ............. Approx. 2600 min
-1
(rpm)
• Rated pressure .......... 18.7 MPa (190 kgf/cm
2
, 2710 psi)
• Oil temperature .......... 45 to 55 °C
113 to 131 °F
