806 Hitch PumpTest

Poloz · Nov 14, 2011

Mowing yesterday w my 63 Farmall 806 and Rhino Flex 15 using a 3 spool Cross valve to control shredder wings when it lost all hydraulic flow on aux and 3pt hitch totally. No flow at all. Can someone tell me the best way to test for a stuck valve or how to test pump? Also location of main pump? Thanks!

Does the PTO work okay?

Ya got steering and brakes don't ya . If not them ya got problems up at the pressure plate . If ya do have steering and brakes then i would look for a blowen O/Ring where the pump mounts on the rear frame or pump to plate. Since you do not have a flow rater this is where i would start first.

Yes steering, brakes and pto are working ok. Where is main pump located?

If you lost all flow most likely the cause is a stuck relief valve. A blown O-ring will usually still move a cylinder or hitch without a load.

3pt hitch will not lift the quick hitch at all.
Is the relief valve integrated into the pump? If not, where is it located? Thanks for everyone's help!
