    Broken impeller screw

    Just when I thought the motor replacement couldn't get more complicated this happens. I just received my motor and was trying to remove the impeller. I have the Hayward Tristar model where a screw holds the impeller in. The screw was worn out and the hex key didn't fit. So I used a vice grip to turn the impeller counter clockwise. I turned little too hard and hear a snap followed by the impeller loosening. Here are some pictures. Any ideas on how I can remove the head of the impeller screw from the impeller? Thanks in advance

    The screw is reverse thread. I'd try drilling and using an ex out.

    Wait. The impelled is loose, so just screw it off. Regular threaded. Install new motor with the impeller and use a new screw.

    Sorry, wasn't seeing the pictures at first.

    Screw is reverse thread if that helps.

    I'd try a drill buy probably just buy a new one on Amazon .... about $40.

    The screw head should pop out fairly easily. Just use something metal about the diameter of the screw and tap it out from the back.

    Thanks. It was late in the night and didn't think to try this

    I'm now wrestling with the question.... do I even need one? This thread seem to suggest otherwise

    Most impellers don't use one. I have installed impellers without the screw with no problems.

    The main risk of unwinding the impeller is if you have compressed air in the filter that blows water backwards and reverses the impeller rotation when the pump turns off.
