Hi guys!

I have a united machinez sprocket with a 19mm adapter installed
I am changing cranks to a 24mm spindle and I need to know if the adapter can be safely removed and the 24mm adapter inserted.

I'm afraid that it will mess up the sprocket

Does anyone even make 24mm adapters?

I've never seen one before but I'm sure that if you used some lubricant and knocked it out carefully, it'll be absolutely fine. Again I've never seen one so I couldn't really say. If you feel worried about doing it and no one can give you a confident answer, taking it to a bike store and asking for advice will almost certainly give you the answers you want. They'll know what to do with it. I had a Titanium 19mm spindle and a bolt had seized on, I heated it up and got it off with force, which striped all the thread out and it's tricky to cut thread into titanium, so I wish I had just gone to the bike store in the first place. Good luck.

If it's the adapter type in the picture, then yes, it's fine to remove it. If it's stuck in there, you can tap it out with a hammer and punch. There's no need to baby your parts, they're designed and made with neglect and abuse in mind.

Yes you can remove it, but do it carefully. You don't want to wear out the Socket Drive interface in the sprocket, as that could give it some wiggle room & cause further damage later on.

Just make sure to hit it out evenly, I would try to find a socket or something that sits on the insert without touching the sprocket, and give it a couple gentle-ish whacks with a mallet. Keep an eye on it & make sure it's coming straight out, not one side before other.

Also, before you buy 24mm cranks, I would contact Empire & have them confirm that the Mutiny 24mm Insert (same exact insert as the United) fits snug on whatever cranks you're looking to buy. Save yourself the trouble of the NIGHTMARE I had to deal with trying to run a 22mm Spline Drive set up with the United Machinez/Mutiny Pentra insert (on going issue still, 2 months later. 100% wish I had went with Bolt-Drive.)

Thanks guys!
I'll be going to a bike shop, maybe they can use a vice or something.

@Tim
I've seen your video with the spindle and how the socket slides onto it. That shit is crazy laughing
Never go with spline drive only cranks
