  • 500EFL Pro Auto rotation gear difference

    Hi All.

    Just doing a major service on the 500 and putting back together. Tightened up the bolt that goes through the AR gear and cracked the plastic. Its a year old original so no worries have a spare so just went to swap it out. The reason I never changed it last time is it has a metal bush in the middle I couldn't get out and the new one didn't have the bush. So looking at it trying to work out how to get the metal bush out I realize they are not the same. The new one has a much smaller ID. So pushed it straight onto the shaft that goes through the one way bearing and it is a neat fit.

    I am sure it is for a Pro as looks identical accept the lack of need for the metal bush. Is this just something they have changed or am I missing something here?

    Cheers

    The Pro one has the metal bush.
    Supposed to stop splitting.
    I've used both types, not noticed any difference.

      I think another difference is you only get 1 in the pack, I have used the bushed one on my ESP before
