3pt Control Overhaul?

[nocash247]

The 3 point on my B7200D (with FEL) is acting erratically and I believe the control lever my be to blame. It dips then raises without a real discernable pattern. The lever has no tension to it at all and flops around (currently helps in place by some bailing twine). With the tractor off, I can stand on the lift arms without them dipping, hence my thought the control system is to blame.
If anyone has any experiences with this problem, rebuilding one, or testing procedures I would appreciate it. I checked for Kubota books online but couldn't find a service manual that covered it for my model.

No need to overhaul the valve, you either just need to tighten the nut on the control lever or you need to replace the 2 spring washers under the control lever.

Lets not forget the often neglected drop speed needle valve either...(if it has one)...

Very interested in this thread as well. I have tracked my issue down to the same location.
Not to hijack but I too can confirm hydraulic cylinder is holding and good hydraulic pressure to the back.
Issue is the lever moving won't make hyd. fluid flow to main lift cylinder change.

My handle is loose feeling too, like it isn't connect to much.

HI Nocash,
Check this link to the service manual #3 and look at page 42.
