    DT Swiss 350 20mm End Cap Removal?

    So, having worked on other DT Swiss hubs where the 9mm QR caps simply pop off I assumed the 20mm through axle caps on my 350 hubs would do the same. No such luck. I don't see a retainer clip holding these caps in place so as of now I am stumped. I know it can't be that hard to remove them but apparently I'm not smart enough to figure it out. What am I missing?

    Those may not be convertible like the 240s hubs are.

    From the DT Swiss website:

    "Affordable Ratchet SystemŽ hubs which are perfect for top end performance all the time down the trail. The 350 IS disc hubs are available in dedicated QR, 15 mm or 20 mm fronts and completely convertible rear hubs with options for 135 QR, thru bolt versions and 142 mm thru axle versions. There also is a dedicated 150 mm option."

    Thanks. I read that on the site but I could not find anything on removing the caps for the purpose of servicing the bearings (I'm not wanting to convert to 15mm or QR) My guess is they will pop out with enough force but I'm not willing to try it until I know that for certain.

    DT Swiss 350 20mm End Cap Removal?

    If they are like OS 240s, they thread on and off.

    Not threaded in, the caps spin in the hub shell.

    Measure the diameter of the adapter.

    Drill a hole the same size in a 3/4" thick piece of wood.

    Cut the wood in half through the hole.

    Now you have 2 pieces

    Put the wood around the end cap and clamp in a vise.

    Wiggle the wheel, the end cap stays in the blocks of wood and are free from the hub.

    Thanks for the help! I manged to remove them by using the through axle as a lever. Note: you need to remove the rotor on the left side to get the cap off. The next problem: looks like the bearings are shot and since they are sealed they're not really serviceable.

    DT Swiss 350 20mm End Cap Removal?

    Sealed bearings are easily serviceable.

    There are plenty of videos on YouTube. Use a dental pick to remove a seal, flush the bearings, dry, re-pack with grease, put seal back on.

    Good point, but only if the bearing does not run rough already/ has rust in it.

    Yeah, I did a little search after my comment and learned that they could indeed be serviced. However, one of my bearings is toast so I'll need to replace them. Thanks again, I learned a lot in the last 24 hours!

    onepivot, can you explain how you did all that? I do not understand how you used the front axle as a lever. Also, what kind of bearing-extracting tools did you use?

    I just happened to come across this thread. It's relevant for some. I have had several others ask this same question on how to remove the DT Swiss 350 end caps. It's just as onepivot explained, but with a little more explanation.

    The press ring that surrounds the end cap is what is physically retaining the end cap to the hub. The actual end cap freely 'floats' in the surrounding press-ring.

    Like onepivot, I usually use the thru-axle as leverage to pop off the end cap. Insert the thru-axle into the end cap, but not so deep that it enters the inner bearing race. Gently leverage the thru-axle as it was a pry bar and the cap will pop off.

    On re-installation, apply some grease to the outer bearing seal to act as a seal or barrier to water and contaminates. Apply a small amount of grease to the inside groove of the press-ring.

    You will then need to press the press-ring and end cap into place. I just use an appropriately sized socket to clear the end cap and gently tap the press-ring into the hub. You're done.

    Good job!

    Cleared2land, what size of socket did you use?

    I pressed the ring/cap with a socket but a think I need another a little small than that I used because the cap is some loose. I need to press it a little more.
