Flowmeter Connection and Test Preparation
IMPORTANT
• 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, then remove the front grille and side cover
(R.H.).
2. Remove the accelerator rod (1).
3. Remove the fuel filter retaining nut.
4. Remove the pipe clamp.
5. Disconnect the hydraulic delivery pipe (3).
6. Install the adaptor 61 (6) to the hydraulic pump (4).
7. Reinstall the accelerator rod (1).
8. Connect the hydraulic test hose (7) (Code No. 07916-52651) to
the adaptor 61 and flowmeter (Code No. 07916-52791) inlet
port.
9. Connect the another hydraulic test hose (5) to flowmeter outlet
port and transmission oil filling port.
10. Open the flowmeter loading valve completely. (Turn
counterclockwise)
11. Start the engine and set the engine speed at 2600 min
-1
(rpm).
12. Slowly close the loading valve to generate the pressure approx.
13.9 MPa (142 kgf/cm
2
, 2020 psi).
13. Hold in this condition until oil temperature reaches approx.
50 °C (122 °F).
