started to start to service my wheels, replacing ball bearings, lubing up etc

i have notice that one of the caps on the cup is no longer stuck to the top of the cup

is it possible to glue this back on? what glue would you use? or is it okay just to let it cover the top with plenty of lube

heres the photos of the loose cap and the cap sitting on the hub ... otostream/

    The plastic cap is a dirt seal - the wheels will work fine but you'll need to keep up with the maintenance, particularly if you ride the bike lots in the rain.
    Make mine an Italian, with Campagnolo on the side..

    I believe you can also buy the seal seperately and cheap. Your bearings will last longer with it.

    If what that shows if a sealed bearing race with the seal out, the the seal should just pop back in. Alternatively, if both sides are sealed, just remove the bearing and turn it around so that the non-sealed side is facing inwards.

    Is that a metal seal that fits over the cone in an ordinary cup and cone bearing hub?
    If so just bend the inside edge a little and tap it back on to the cone, not too far or it will rub, compare it to the one on the other side.

  • Hey! i joined because I stupidly managed to remove the dust cover from the cone. I don't want to buy a complete axle just for this part so I'll give this a go. Thanks. I got an Orbea Aqua last May and ride it almost every day. Never thought much about maintenance but am finding that I should be doing a lot more!

    Thanks for the answer to the OP - this will help me too!
