deore xt m730 freehub, is there a way to remove the oil port/dust cover ring?

I'm trying to switch out the freehub on this hub and wondering if it is necessary to remove the ring that slides to expose oil ports. It's located externally and has more to do with the hub bearings than the internal mechanism of the freehub. It would be nice to transfer it onto the new freehub. I was able to remove the piece of rubber that wraps around inside of it. How do go about removing it, if it's possible? I know it may be difficult to tell what I'm talking about without a photo. I was hoping someone had experience with this and could some how decipher what I'm talking about. Thanks.

If I'm understanding you, you want to transfer the original right-side dust cover/oil port from the original cassette body to a new one. If you're changing the cassette body to a Hyperglide (which is usually the only reason to change them) then this won't work- the old dust cap will block the threads for the Hyperglide lockring. You should use the correct right-side cone for the cassette body, not the hub. It will have a rubber seal on it.

FWIW: I had a M730 hub converted to Hyperglide 9-speed on my touring bike. It worked great until the body failed- while on tour in Canada. Fortunately this was a supported tour, so I got to the mechanic, he loaned me a wheel, and had my original wheel repaired and working almost perfectly that evening. The TourBC folks are great!

I see now that the part I'm attempting to discuss is most likely pressed into the freehub and not intended to be removed. I understand that each freehub is unique and comes with its own cone, hardware, seals etc. If attempting to transfer certain freehubs it truly is best to buy another donor hub and use the accompanying hardware.

No problem. Just don't ask me to cook. I can't cook worth a darn.
