How is a DAT tape guide roller secured??

  1. I picked up a second unit and I'm repairing my Sony DTC 700 DAT tape unit by
    mixing and matching parts
    One thing I noticed is that the tape guide rollers that wrap teh tape around
    teh drum and that you adjust to align the tape to the head are all loose.You
    can actually pull them right out of the blocks on both of th etransports I
    have !
    This is causing a problem because one pops up and the tape is out of
    alignment so I get no audio until I reposition it.
    It looks like its a press fit that has just become loose with age and I'm
    inclined to super glue it back into the block that it attaches to
    wondering if anyone has seen this and can advise how to keep this where it
    The model is Sony DTC 700 and the guide is item #622 on page 57 of the
    service manual
    I have teh servive manual and can post it on my website if somebody wants to
    see it
    Thanks in advance

    Hello Bob,

    I have a problem with the ALPS switch and I need the part number of
    the gear of it. It breaks easily and without it, the caution light
    goes on and the tape won't run.

    If you can post the service manual for the DTC-700 will be great.

    About the pin that get loose, I would go with the super glue.
