DT SWISS threaded ring insert removal tool

rs6mra1

I bought a set of new DT Swiss wheels for £150 (RRP £290)and they come with the 350 hub which retails for about £120 (rear only)
I now have to replace the shimano freehub for £60 but doing so I would like to remove the bearings and regrease or replace them if required.
The reason i want to regrease or replace the bearings is due to them seizing up and hence me not being able to remove the freehub and damaging it.

Now the tool that is required to do this is £60, so that's £120 down already on a set of wheels that cost £150.

I have an old set of wheels that I am using now but i can't come to terms as to whether it is worth spending the money or ditching the wheels.
Do freehubs and the servicing of other wheels amount to the same sort of outlay or not?

...i got one for my 190 hub

assuming the 350 has similar arrangement...

hub bearings can be accessed enough without special tools, use a pick to carefully remove the bearing seal, squish fresh grease in, replace seals

if the 350 freehub body has the same bearing arrangement as the 190 (and 240), you can replace the bearings this way...

inside the fhb there is a tube that sits between the inner races of the two bearings, this can be pushed to the side enough to allow the outer bearing to be tapped out

once that is done, the tube can be removed through the hole leaving plenty of room to tap out the inner bearing

bearings in the 190 are 15x21x4 6702-2RS, but i think the ones in the 350 may be different

improvise a press with nuts, bolt, washers, and an old bearing to press in the new ones

If you just need to replace the freehub, you don't need to remove any bearing. Poo the hub cap off, slide out the freehub, slide in the new one with the new hub cap job done

Sungod is right. You can do it the way he has decribed and that faff involved is downside to DT hubs. Fit the best bearing you can so this job comes up less frequently or not all.

Poo the end cap off. normally it me that makes the typo's.

Thanks very much guys.
I couldn't pull the free hub off as it had seized. Eventually I took a hammer to it based on a video I saw. By then it was late and the damage had been done.
