Flowmeter Connecting 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.
• The flowmeter does not provide relief valve.
Therefore while testing, do not close the flowmeter loading
valve completely.
1. Remove the 3P delivery pipe (2) from hydraulic pump (1).
2. Set the adaptor flowmeter (4) (see page G-48) and adaptor 53
to the hydraulic pump (1).
3. Connect the hydraulic test hose (7) (Code No.: 07916-52651) to
the adaptor 53 and flowmeter (Code No.: 07916-52791) inlet
port.
4. Connect the another hydraulic test hose (6) to flowmeter outlet
port and insert to the transmission fluid inlet (3).
5. Open the flowmeter loading valve completely. (Turn
counterclockwise.).
6. Start the engine and set the engine speed 2700 min
-1
(rpm).
7. Slowly close the loading valve to generate the pressure approx.
15.7 MPa (160 kgf/cm
2
, 2276 psi).
8. Hold in this condition until oil temperature reaches approx.
40 °C (104 °F).
(Reference)
• Adaptor is included in the adaptor set (Code No.: 07916-54031).
