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.
• Set the main change lever and shuttle lever in Neutral
position.
• Set parking brake lever in parking position.
1. Place the disassembling stand under the transmission case.
2. Remove the right rear wheel.
3. Place the disassembling stand under the right rear axle case.
4. Disconnect the differential lock rod from pedal.
5. Disconnect the delivery pipe for power steering or delivery pipe
for 3 point hydraulic from hydraulic pump (2).
6. Install the adaptor 53 and 54 (see page G-71) to the pump
discharge port.
7. Connect the hydraulic test hose (3) to the adaptor at hydraulic
pump (2) and flowmeter (4) inlet port.
8. Connect the other hydraulic test hose (1) to the flowmeter outlet,
insert the hydraulic test hose other end to transmission oil filling
port at PTO case.
9. Open the flowmeter loading valve completely. (Turn
counterclockwise.)
10. Start the engine and set the engine speed at 2000 to 2200 min
-1
(rpm).
11. 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. 55 °C (131 °F).
12. Open the loading valve completely.
13. Set the engine speed. (Refer to "Condition".)
14. Read and note the pump delivery at rated pressure.
15. Open the loading valve completely and stop the engine.
