Help with DT Swiss 240s axle conversion

I've picked up a rear DT Swiss 240s hubbed wheel, and it's set for 135x12. I want to convert it to QR. I have bought the "DT Swiss Conversion Kits 12mm to QR Rear" from CRC, but when I pop on the two end caps, I end up with too wide a hub. Back to the order desk to guess which hub kit has the shortened axle. I find what I think is right, which is the 12 to QR rear for the 440s, because that's all I can find with what looks like the right axle. I turn to the DT Swiss hub disassembly document, but can't get past the locking mechanism inside the freehub and the hub itself. The document has a reference to a special tool, with no indication what it is or what P/N it can be ordered on.

Who's a 240s expert and knows what I need to do to get this thing apart?

Thanks!

I'm here to save the day! :thumbsup:

You need this tool in order to remove the ring nut. Then the bearing comes out. BUT, you may not need to remove the bearing(s) if you get the correct kit. The tool is shown on page 25 of the 240s manual.

I'm having a hard time getting my head around a 130mm x 12mm TA rear hub though. I don't see it in the manual, you might need a new axle and a pair of bearings. The tool will help with that if you do need to replace the bearings and axle.

Monte,

That's great, thanks for that -- so much for tool free disassembly which was claimed on some Sea Otter video.

As you noted, the wheel is a bit of a custom job. It's labelled as an EN 144, which is an OEM DT Swiss wheel made specifically for a Scott Ransom LTD, which is a UK only model I believe. Other than this rear axle, the wheels are exactly the same as the EX 1750.

It's all in the exact wording. DT 240 hubs offer tool-free SERVICING, not overhaul. The ratcheting mechanism can be serviced (cleaned and re-lubed) with no tools but the ring drive needs the special ringdrive socket. The DT toolkit consists of drivers for the sealed bearing units and this socket. The ring drive needs to be removed to overhaul the hub with new bearings.

Maybe bearings can be replaced with normal workshop tools (hammer/punch) but not the ring drive.

Your comment has come up a few times over the years and it's all in the interpretation of what was said versus what you think you heard.

Here's a couple of hundred dollars worth -

Ah, missing information. No wonder it didn't work.

Check that the end caps are fully seated. I had to grind a small lip off of the new end caps when I converted my hub from QR to 10mm RWS as they were slightly different from the originals.
