    Hi, I have a Genie 60 ft stick boom, with a diesel engine. I am having problems with the boom swing. It will swing, but it really jumps a lot and jerks.

    I have replaced the joystick control and have also replace the circuit board.

    Is there a hydraulic solenoid that could be causing problems?

    Also, the machine will not walk fast. I saw on the other thread the limit switch on the rear of the boom may fix this issue.

    I have the manual on this machine
    I appreciate any help or pointing me in the right direction.

    How well does the swing operate when using the lower controls?

    I tried the lower controls and it does the same thing. It seems to swing back and forth when you move it left or right. thanks for your reply.

    Are you sure your swing unit and pinion gear are in good shape?

    Or the lower bearing for the pinion shaft in the swing gearbox.

    I checked the pinion and ring gear today on the turntable. They look to be ok. I did not see any wear or bad spots.

    I looked at the pinion bearing and it seemed to turn correctly. No wobble or excess movement.
    I can use my hands to push on the boom and it will move back and forth a little but I dont think this is excessive.

    Any idea how to test the hydraulics going to the swing motor? I appreciate the help and feed back. thanks

    The main boom has to be down in order to fast travel, if you have the main boom raised up very far, it's designed not to fast travel.
