How to change bearings DTswiss240s (Front hub)
Moderator: robbosmans
Hey guys,
Just wondering if anyone has any tips on how to change bearings on a straight pull DTswiss240s front hub?
Can it be done with out DtSwiss specific bearing pull tools?
I have opened her up (taken the dust covers off) and it seems like there are 3 parts, but no way to pull the bearings, is it a matter or pulling them out of pushing them through I have no idea.?
Also does anyone know if I can use these 6803 bearings? I'm not sure what the difference is between them, or can someone recommend a decent set?

Have not seen one of these hubs, but if it's the case that you have dismantled the hub and are left with the axle sticking out each end it means that the axle has shoulders which are simply being held in place by each of the cartridge bearings. A gentle strike with a soft hammer on one end of the axle should dislodge one of the bearings, and then you just put the axle back in and strike again to remove the other bearing.

The 240 front axle does have shoulders.
Here's a link that will get you to the service manual.

The shoulders on the axle are inside the hub shell - you cannot see them.
Front hub bearings tend not to wear out. Perhaps they are slightly mis-aligned. try a gentle tap with a socket over the end of the axle - both sides.

I wish I read that a bit earlier... I did check each bearing on it's own and it appeared one had a rough spot.
When I put the new bearings in I had a similar thing were it felt a little 'tick' in one part of the wheel might need to change the caps? I tried my other dt240s they are smooth as silk!
The dodgy hub is on my training wheels so i'll leave it as a mechanics lesson learnt haha
Btw, if anyone is planning to do this... I used an old skewer and a washer and an old bearing to press the knew ones in place works a treat!
