Got a bit of play in my rear wheel, hub is a powertap pro, so I guess its new bearings time, had a look at some info on line & replacement looks pretty straightforward (I service all my own mtb hubs as and when). Other than the obvious of not 'twatting it' with a hammer is there anything to be aware of/watch out for before I set to it?
A berm? were you expecting one?

    If you service yourself you affect the calibration of the torque tube or worse damage it. You have to send of to Paligap and part with £100 I'm afraid. Personally given the cost of parts for a Powertap I would not touch them I send them to Paligap. However they will take there time. 2-3 weeks!

    I replaced my bearings about 18 months ago - no problems. I recommend that you spend an extra few pounds on decent branded bearings - i.e. SKF or Ina. As you say, don't tw*t it with a hammer, use a long bolt and various sockets to pull the axle out.

    Replaced the bearing in my PowerTap plenty of times. The wheel is able to withstand the pounding from Surrey's "finest" highways, so appears unconcerned at me nudging out the bearings with a hammer and an aluminium drift. Notably the calibration appears unaffected between bearing changes. It's basically a function of temperature; around 505 when cold, 512 when hot.

    Cheers for the info, it's pretty much what I thought, as discussed I don't think a bearing change, if done with care will result in the death of the hub.... considering the pot hole infested roads it is ridden on regularly and I cant be without for 3 weeks :shock:

    For a shop though remember if the customer find a problem after a bearing change I have done I am liable hense my advise. I do not fancy having to shell out for a pailgap repair if the customer thinks there is an issue as they will charge even there isn't. If you are doing it your self you take the risk even if it small.
