backhoe function problem

[gurnbow]

Hi.my username is gurnbow. A friend of mine is having issues with the bh75 hoe on his b3030 Kubota. The hydraulic system got over pressurized.the vavle bank has been rebuilt and the hydraulic pump has been replaced

. Now he can only run one function at a time. Does anyone have an idea where to look next

If the BH was removed during the repair work, make sure it was not reconnected backwards.

Sounds like power beyond from the upstream source is not hooked up to the backhoe valve inlet, how many hyd lines are to the backhoe valve?
