    Hi,
    Does anyone have a suggestion or tips for a "stuck" roller holder? The post that slides in to remove the
    the roller will not slide back out to secure the new roller. It is the second unit and the BLUE form roller mount on the op side.
    Things I have already tried:
    Removing the roller to make sure it was not impeding it, it would not slide back even with the roller removed.

    Penetrating oil, mild solvent and type wash to try and loosen it in case it was seized from ink or debris

    Using a big screwdriver to pry it back out, I have done this to the point of being afraid of breaking the piece.
    Any suggestions woulg be awsome, thanks!

    Can you get a small handled lever behind the pin to push it back out. I have used that method in the past. I have tool that does that job, so something in your area should be available in a tool shop.

    Lift the spring loaded knurled up with one screwdriver and push pin out with another from behind

    There is not much room yo move in there. I could try. Do you have a picture of the tool? that might help me figure out if it will work.
    Thanks

    I have tried that several times. the knurled nob should not even need to be lifted to move it in that direction, but yes, I tried.
    Thanks

    Thank You for all the suggestions!! mrheidelberg wins with the small lever suggestion! I was able to get it in position and with some serious pressure it popped out!
    Thanks again

    In the future you might want to consider using a slap hammer to gently pull it STRAIGHT out. Its often the side loading of the shaft that causes binding.

    Depending upon the model and year of press, isn't there a knurled thumbscrew that could be removed to allow for attachment of the puller? I remember using the roller bearing puller with an adapter that was fabbed up in our machine shop, that would slip over the knurled thumbscrew on our older Speedmasters.
