Swiss DT240 hubs

I've got a DT240 rear hub left over from a failed project on a second hand bike. It's sat in the corner of the garage for several years now. Thinking about attempting the dark art of wheel building I dug it out yesterday, but found that it has almost locked up. The free hub rotates and engages well, but the main body of the hub is very stiff on the axel. Whilst the free hub is supposedly a tools free service, the rest of the hub requires a £100 + set of tools, which I don't have.

Do you think it is worth getting it professionally serviced, so I can (try to) build it up into a wheel, I was thinking Swiss DT RR1.2 rim? Or as I don't fully know the history of it I should save my money and by a new hub? Probably couldn't stretch to a direct replacement, maybe 105 or Ultegra.

Thanks

    I have 240s on my MTB and when the bearings went on the front wheel took it to an LBS. They replaced bearings and serviced for about £30 - 40. This is the only fettling I've ever had done in a LBS - simply because didn't want to buy the kit (basically a set of 'punches' to knock out the bearings.

    DT 240s are nice hubs so worth having fixed IMHO.

    Thanks for the comment. With the bearings readily available on ebay, is replacing them something that could be attempted without the specific tools? Or would an attempt to "bodge it" be doomed from the start?

    You can just knock them out apparently with appropriatly sized shafts - I just didn't fancy risking it as at the time they were my only set of wheels (so would have been off riding if I screwed it up). As they are just lying around in your case not built up, not much to lose really.

    Have you had a look at the manual for them?

    I'd have a go at changing the bearings yourself, as the other reply suggests. Socket sets are useful stand-ins for bearing drifts, in a pinch. These things are pretty simply constructed, you just need a little mechanical sensitivity, to know when you're destroying something..! And imagination to find something to stand in for the correct tool.

    For bearings, I suggest you start off somewhere like here:
