Replacing bearings in a DT Swiss 240s hub and freehub

The 240s hub uses a 6802 bearing on the non-drive side, and a 15267 on the drive side.
The freehub uses two 6802 bearings.

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.

[@TheCyclingMan]

Good tip thanks!

[@dannyholder1359]

Very nicely explained and shot. Professional. Thank you.

[@nicktonks9817]

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.

[@TheCyclingMan]

Nice tip!

[@Stoffendous]

Thanks for this excellent demonstration!

[@TheCyclingMan]

No problem - hope it helped!

[@testingtesting972]

Just about to start this journey when I get out of bed….will go see the lovely team at Spoke N Trail (Noosaville) to buy my replacement bearings.

Very useful video cheers mate.

[@chizhang001001]

very nice video, just note DT 240 rear hub comes with different bearings, mine is 6902 on DS and NDS

[@TheCyclingMan]

Thanks Chi Zhang! There are subtle differences on the different variants of the 240 hub ...

[@kendericklin]

@@TheCyclingMan how do we find out what type of bearings we need on DT240?

[@edeag3]

@@kendericklin see the manual, 6902 for disc versions rear and both fronts and 6802 for rim brake rear I believe

[@KOL630]

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!

[@bigalsbash]

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.

[@TheCyclingMan]

Yes - good tip - gives more leverage 👍.

[@davidgeorge9233]

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?

[@TheCyclingMan]

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.

[@tuber7853]

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

[@TheCyclingMan]

That's the Hope Hub Support Tool - super useful and not expensive! Search eBay for DT Swiss Ratchet Removal.

[@bostonbright2533]

What RRP Kit did you use for pressing the bearings in? Can only find a kit that works for a 6802 bearing but not the 15267 bearing.

[@TheCyclingMan]

It's Kit no 10 I believe - OD 26, ID 15.

[@kb1jki1]

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

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?

[@jamesbutler1949]

Hey. Are those the rims with the Oxic coated brake surface ? I was under the impression that it would not wear away!!

[@TheCyclingMan]

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!

[@trintorian]

Is there any tool I can use to extract the bearings safely from a brand new , but damaged freehub body for the DT 240s?

[@TheCyclingMan]

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.

[@apv1]

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?

[@TheCyclingMan]

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.

[@schneefoen]

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? < kzbin.info/www/bejne/iqvUi6uqjJmrgM0 > 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.

[@TheCyclingMan]

Possibly - noises like this are always tricky to track down!

[@rexfest]

can you please link all of the bearing adapters that were used in this video? given that i would use the same bearing press.

[@TheCyclingMan]

It's Kit 9 for the 6802 bearings - think I had to improvise with the others!

[@rexfest]

I seem to have 2 x 6902, and 2 x 6802 bearings for my rear 240s hub. Am I mistaken? Or do you have a different 240s?

[@TheCyclingMan]

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.

[@shreded7]

I also have a 240s with 6902. I think this hub is a special system hub, but process is the same.

[@xawerionify]

Can you measure the rod size in the RapidRacerProducts press?

[@TheCyclingMan]

IIRC it's M8 but will check next time I have the set out.

[@ulrichemmer4134]

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!

[@TheCyclingMan]

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!

[@yuriyganusyak]

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.

[@andrewmcgaha9629]

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?

[@colw07]

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

[@TheCyclingMan]

No - just need something a fraction smaller than the bearing and a hammer. Old used bearings make good drifts, as do sockets.

[@foxhound143]

Did the tool come with adapters or you had to buy them separately?

Unfortunately you have to buy the adapters separately.

Do you know which bearings the 350 freehub uses?

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.

[@martynstokes9289]

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.

@@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

Hy, I have a problem to remove the bearings on a front wheel from DT Swiss. Is there any tool or hack? It doesnt work with the VAR bearing extractor kit. Should I use a center punch?

[@TheCyclingMan]

Have you tapped out the axle? This usually takes out the first bearing. Then you can flip it around to take out the second bearing.

[@Christian.....]

@@TheCyclingMan That works for the rear wheel, but for the front wheel it seems to be more tricky?! Anyway, I have already purchased an bearing puller www.bearingprotools.com/products/bearing-puller?variant=6945719943226 and waiting for another order with stainless bearings. With the puller it will works for sure. But the order takes time so i must wait some weeks.

@@Christian..... I've changed the bearings in the front wheels a couple of times but don't remember any special procedure I followed. I may have used the RRP tool (tidd.ly/82d76865) which also does bearing extraction. Next time I do it I'll let you know what I did.
