UT bearing circlip removal

In Ultra torque chainsets, the Drive side bearing is retained in place by a circlip... I have removed it a few times, but always with great difficulty, as I haven't found a tool for the job yet... normally I use two tiny flat screwdrivers and try to get some leverage to pull it with quite some struggling...
Is there some form of circlip pliers which are bang on for the job? Normal ones seem to be designed for circlips with holes...

Thanks

    just hold and pull one end and then do the other.

    it is not like it is fragile.

    Needle nosed pliers to do as Nick suggests works for me

    It's not that one... it's the one that retains the bearing, sitting on the UT axle
  • It's this one I mean

    See what you mean. I've never dealt with any circlips without the holes for the pliers.

    Crazy Italian engineering!

    as you do now. screwdrivers.

    Yes, but when it sits in the groove, it's a hell of a job to pop it out... was wondering if there was a tool to make the job a 3 seconds rather than 5 minutes struggle

    Can you not still prise the ends apart with circlip pliers?? I have an adjustable pair that I feel would work in that situation.

    Is that what the bearings look like? No seal on the inside??

    That is what I am wondering... I don't own a pair of plyers like that and don't want to waste money if they don't work... need someone with hands on experience...

    The picture is of bearings with Si3N4 balls, they don't really need seals and normally come without... the steel ones have seals, but they get rusty regardless

    You see the ends are tapered. They are like that to get a pick (screwdriver) in and lift it out and around.

    that's what I currently do, but it's anything but easy... a hit and miss... need a dozen attempts before succeeding... how come Campagnolo and Park haven't come out with a 50 pounds tool to do this simple task?
  • Got it!

    they do use circlip pliers combined with a small flat screwdriver... censored !

    Spooky! That's what was happening in my mental picture of how my circlip pliers might work!

    Never done the job personally, but as suggested, use a pair of external cir-clip pliers. I would buy a cheap set off ebay and grind the ends if necessary.
    Make mine an Italian, with Campagnolo on the side..
