Hunt race aero bearing removal

Hello,

I am just trying to remove the bearings on my hunt aero race wheel set pre 2019.

I’m at the point where I am about to tap the spindle out to get to the bearings.

My question is - which side of the spindle should I tap out - the drive side or none drive side?

I’m guessing the spindle will have a lip on it where the bearing will sit so getting it out the right way will matter.

Thanks in advance!

    Is the the NDS cap threaded on ?
    Normally it's tap out from the drive side to remove the axle and nds bearing .

    Hi,

    Yes the NDS cap is threaded on. I’ve given it a few tentative taps from the drive side but not moved yet.

    It doesn’t look like it but is there a spline lock ring nut on the drive side that you have to remove first?

    Thanks

    Why not just drop Hunt a line and they can tell you exactly what to do?

    The camera down the willy isn't anything like as bad as it sounds.

    have you tried their live chat thing or giving them a call?

    i had to call them a while ago and they were quite good.

    You have Hunts? 😱🤣🤔
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.

    no - i have built a bike with them for a friend and they were faulty out of the box which is part of the reason i have such a low opinion of them

    If it has a star nut on the drive side then it comes out the NDS
    The star nut comes off to remove the driveside bearing

    If the treaded NDS cap has flats on it it should screw off ,is there space on the drive side for a hex key to hold it to unscrew the nds cap ?

    Pics of tge inside of the driveside would help

    Hi,

    All sorted now thanks. I gave it a few good taps from the drive side and axel popped out with one of the bearings, so all good now and can replace them.

    Interestingly, non drive side bearing in really good condition and drive side bearing completely worn out - makes sense I guess!

    The drive side is more open to water ingress.
    When installing the new bearings, I'd put the drive side in first, since the axle will be out of the way. Only install by pressing/tapping the bearing on the outer race to prevent damage.

    I'd press/tap on the inside race when fitting to an axle. Outside for in a housing.

    The bearings slide easily on the axle, but are pressed into the hub.

    Might depend on the design. I'm sure mine are the other way round.
    Tap onto axle, slide into housing. I'll find out for sure at the end of summer.

    In summary, tap on the race with the tight fit.
