    Default Latitude gear and worm disconnect CEM60



    Anyone using the CEM60. I have notice a weird "disconnect" with the Latitude grub screw and gear. I use the Polemaster, if during alignment I overshoot and need to lower the latitude for a few degrees the gear and grub screw are separated until it becomes re engaged .

    This is Ioptrons answer , I could not get my head round the response

    Hi Trevor

    If you release the ALT locking nuts too loose, the gear might separated from the worm. It is OK during coarse adjustment. During polar alignment, you would just loose the ALT nut a bit .
    If this happens when the ALT locking knob is almost tightened, you may need to adjust the alt gear position, which is locked by three small screws.

    I asked Ioptron :

    Should the gear and grub be in contact all the time ?
    How is the adjustment made if I need to bring the gear and grub closer?
    Does the adjustment of the Latitude bolt need feeler gauges ?
    Whats the ALT locking nut ? (singular)

    Does my video show an issue ?


    As I indicated , should I overshoot during polar alignment I have to pass the disconnected region where the gear and worm are not engaged


    Ok ................

    Anyone seen this "problem" and knows the correct way to adjust the worm , Gear gap IF necessary . I can see the 3 screws involved on the crescent gear. I'm worried the lack of contact could lead to grub damage as typically I do a polar alignment each session as I can quite justify an OB :-(
