    Default 4 wheel steer problem

    i have the 4 wheel steer switch in the 4 wheel steer position and only the front wheels turn (the rear arent aligned), and if i switch it to the 2 wheel steer when the light is on, and turn the wheel it blows the 20 amp fuse and kicks a 50-56 code

    i tried disconnecting one solenoid at a time on the valve block in the back it still blows the fuse if i remove either of the top 2 solenoids
    if i disconnect the botom solenoid it doesnt blow the fuse

    what does each solenoid do?
    does anyone have a service manual i can download?

    ulmn,

    The 50-56 error code is referencing a communication error. There is a short in that circuit. Is this intermittent?

    It only happens when. Flip the 4 wheel steer switch

    I pulled the 3 coils off the valve block in the rear

    The bottom coil is bad only reads around .4 ohms
    The other 2 read around 6 ohms

    Does anyone know if there is a parts microfiche for the toolcats online?

    What about a PDF copy of the service manual?

    Using Windows IE go to Bobcat.com, then at the bottom of the page, click "Parts and Accessories" under "Ownership".

    Click "Parts Catalog", then download and install "ArborText IsoView".
    Hold "Ctrl" (Control) and click on a picture or a Link, to open it in a new Tab.

    No need to check. Thats why I asked if the engine was laboring. How many hours on unit? Have drive motors ever been replaced? See "Weak drive on 5600s' thread.

    Default Re: 4 wheel steer problem

    When trying to turn while using 4-wheel steering on hard surfaces like asphalt and Im at a dead stop, I have to crank my engine up pretty good to get my D-Series tires to turn. If I don't the steering feels 'notchy' and it's like trying to turn the wheels on a very heavy vehicle without power steering. It's better in 2-wheel steer but it's not like power steering in a car at all. I don't remember the steering being this difficult when I first bought it (new) back in 2008 but it does seem to be getting worse and worse the last few years. I just really noticed it today when I was moving 1 ton pallets of rocks around. Can I assume this is normal? Is there something that going out on me?

    Thanks, DEWFPO

    Sounds like its time for a pressure test and a steering relief test.
