(2) Hydraulic Pump for Power Steering

Flowmeter Connecting and Test Preparation
NOTE
• When using a flowmeter other than KUBOTA specified
flowmeter (Code No. 07916-52792), be sure to use the
instructions with that flowmeter.
• In this hook-up, there is no relief valve. Therefore while
testing, do not close the flowmeter loading valve
completely.
1. Open the bonnet and remove the front grille.
2. Remove the side cover (R.H.).
3. Remove the steering wheel and then remove the meter panel
and panel under cover.
4. Remove the plug of power steering gear box and then set the
relief valve pressure tester (use adaptor D). (See page G-33.)
5. Disconnect the power steering delivery pipe (1).
6. Remove the pipe joint (3) and set the adaptor joint (4) (See page
G-45) to the hydraulic pump (2).
7. Set the adaptor joint 66 (6) to the adaptor joint (4) of the
hydraulic pump (2). (See page G-40.)
8. Connect the hydraulic test hose (7) (Code No. 07916-52651) to
the adaptor joint 66 (6) and flowmeter (Code No. 07916-52791)
inlet port and power steering P port.
9. Connect the another hydraulic test hose (8) to flowmeter outlet
port.
10. Open the flowmeter
counterclockwise)
11. Start the engine and set the engine speed at 2600 min
12. Slowly close the loading valve to generate the pressure approx.
11.8 MPa (120 kgf/cm
13. Hold in this condition until oil temperature reaches approx.
50 °C (122 °F).
