Very helpful - thanks very much! My only comment is that you don’t need a spacer for pressing the drive side hub bearings in (@3:25) if you press the bearings in the other way around (i.e. press drive side bearings first, reinstall ratchet ring, insert axle, then press non-drive side bearings). Not an issue if you have a suitable spacer lying around the workshop, but for those of us that don’t it’s one less tool to buy 👍 Putting the components back together in this order also allows you to reinstall the ratchet ring before inserting the axle, should the hole in your ratchet ring tool not be wide enough to accommodate the axle.
Leave the cassette on the hub, just pull the cassette and hub of as one unit. This also removes the outer drive side end cap at the same time, simples.
I’m just trying to find this out myself. I have a DT Swiss 240S hub and I belive there are two different types of bearing in the hub shell. Some bike shops say they’re the same but DT Swiss have said they’re different. It’s highly confusing. I recommend you wipe the outer seal during removal and check the text on the bearings both sides before buying new ones!
Thanks for a great video. I just did the service. A couple of things I descovered reinstalling the wheel bearings I would install the drive side bearing first as you can use a normal socket to seat the bearing before the shaft goes in also the spacer washer needs to be seated in the rachet grove I used grease to keep it in place also my ebay tool did not clear the shaft so I could not tighten the drive side down with the shaft in place.
Great video 👍 Interested in what you said about pre load by adjusting the bearings, I was under the impression the 240s is pre loaded by the spacer collars and does not have any actual adjustment, it’s done by fine machining tolerances of the spacers?
Thanks. There isn't any adjustment like with Mavic hubs for instance. But I still find you might need to adjust the bearings to get them to run freely - same is true with most cartridge hubs. If you tap them in lightly they might be just fine without any adjustment.
what is that gray cylinder and where to get it from online (which the wheel hub rest on it when removing the freehub spacers)? what is ratchet removal tool? can relink the removal again as the product page is not found. thanks
Yes Oxic coated.They wore away very quickly in the winter weather we get here on Dartmoor in the UK. Only used with their recommended Swiss Stop pads. But they did replace them under warranty and I sold the wheels on! Breaking with them in the wet was hopeless!
where did you get the nylon ring over the tube supporting the hub shell at the flange you are hammering the bearings down into? I suppose one could just use PVC

Extracting bearings is easiest with a drift - but if you mean reusing the bearings I personally wouldn't - it's very difficult to not damage them at least slightly when you extract them.
Hello, I'am looking for 15x26x7 bearing for my DT Swiss 240 hub (installed on DT Swiss ERC 1400 DB 47 spline wheels). Unfortunately, the on-line shop you suggest has only the basic Endruro bearings, as the 15x26x7 hybrid ceramic ones are out of stock. Do you know any alternatives? Thank you in advance, kind regards, George.
I think it's the same freehub - so should be 6802 bearings. But if you pull off the freehub you should be able to see or measure with some calipers. 6802 bearings are 24mm outside, 15mm inside.
Hi, excellent video about the rear hub maintenance! I have a DT Swiss 240 rear hub with star ratchet, the problem is that the freewheel is so stiff that it doesn’t freewheel when I stop pedalling...It even transports the chain that the chain jumps off the cassette. It is almost like an engagementof the ratchets in the reverse direction...and it is unusually loud as well. Do you have an idea what it could be- can’t use the wheel like this... Do you always replace the sealing ring when you do hub maintenance? Is there a way to check the bearing sizes you need prior to dismantling? Thanks!
Thanks Ulrich. You'll really need to take it apart to see what's going on. A lot of times just cleaning it and re-greasing will do the job. No you don't need to replace the seal every time. You should be able to find spec sheets for your specific hub - to check the bearing sizes. Good luck and let us know how you get on!
Do you mean the hub support tool? That's made by Hope - surprisingly handy - although a couple of blocks of wood would do the same job. Wiggle: tidd.ly/983c8ecb
love the video!! Is it completely necessary to have a bearing press for re-installing the bearings into the free hub body? Thanks; need to do a swap at the moment
Hi can you please Link to The ratchet removal tool, really dont want to pay for a dt swiss original, other then that i have The enduro press with all The diferrent sizes, Great video, hope you respond
Any chance to do this tutorial for the fron wheel? I have no idea how to get the bearings out since the axle is flush with the inner bearing race on both sides...
@@TheCyclingMan Actually solved it - there is a tool from Dt Swiss that sits in the axle and that can be used to knock the bearing and axle out on the other side. There are 3D files of this tool on thingiverse for 3D printing
I can't double check since I've now sold on that wheelset - but pretty sure it's as described in the video and its description on my hub at least. Just double check when you remove them.
Hey m8... thank you for the video. RRP definitely needs to send you a check :) Which ceramics did you use (the link is not going to a particular bearing) and what are your thoughts so far?
Sorry for late reply Andew McGaha and thanks for your comment! I've been missing notifications from this channel! If it's not too late - I got them from Aire Velo.
Do you have any strange pinging sounds from your rear wheel? We have similar wheels and mine makes that noise when riding mainly up hills. Also do you prefer dt Swiss hubs or hope hubs?
Are you sure that's not coming from the spokes? Try applying some grease to the spoke intersection and see if that helps. My Hope hubs on my mountain bike need far less attention. But they only have 4 pawls so are quite slow to engage. The star ratchet for road is better in this respect. I've not tried the newer Hope hubs with more pawls.
The Cycling Man : could one possible reason be: under bigger stress the cogs of the chainwheel "plucking" the chain-a little like pickin' the string of a guitar maybe? < th-cam.com/video/TzqZxtW4xJk/w-d-xo.html > the resulting vibrations could then continue from the chain (or the chainwheels) via hub-body to the spokes. i have this soft tone pling-pling on my mountainbike's DT swiss spline-wheels all the time when pedaling really steep. kind regards.

Is there any tool I can use to extract the bearings safely from a brand new , but damaged freehub body for the DT 240s?
Extracting bearings is easiest with a drift - but if you mean reusing the bearings I personally wouldn't - it's very difficult to not damage them at least slightly when you extract them.

I had the same issue after reassembling the hub. The problem was the washer over the threaded ratchet ring, which I didn't press in fully.
is this the same as DT Swiss disc brake wheel 240s bearing size
Sorry I'm not sure - DT Swiss normally have service manuals and diagrams if which should list the size of the bearings.
