is there anything i can check for, before i remove hydraulic pump? There is no tilt, raise, or steering. I'm leaning towards pump being bad because the motor spins when any of the three commands are called upon, but not sure if there is a way to test pump flow. Also, is there a way to lilt mast down to get more room to work on things with no tilt action at this time? it was tilted all the way back when it broke down and clearance/work room is minimal.
