I sent the one on my /7 to Bob's when it started to leak. That was several years back and it's still working like a champ. I'd bet any of the regular shops mentioned here would be fine choices depending on your location (those Kurt mentioned, Bob's BMW, Engle Motors, the Beemer Shop, etc...). Good luck!

Yes
I do most of my own work but haven't yet invested in any rear end tools. Probably because I've yet to see a leaking rear end on any Airhead I've ever worked on.
Funny this topic just came up when it did. I just pulled my RT off the lift due to a oiled up rear wheel or should I say a lot of oil on the rear wheel from someplace. Anyway, sadly, I don't wash my bikes a whole lot and when I did the other day, the wheel had a lot of gunk on it from oil collecting.
First thing I thought was the final drive was leaking and yep, the sight level showed oil below the full mark. Lucky for me, the problem was a bad crush washer on the drain plug I stupidly didn't check when I changed the gear oil the last time.
As for the other seals, knock on wood, I am still going strong at 240K miles with only one spline change. So, LOL I have never invested in tools to do final drive work or transmission work as I never have had to. I have a local small retirement shop who works on airheads and provides me with coffee and conversation.
Where are you located at? St.

240k is pretty impressive.
I'm in southern central MI, about 20 miles north of the OH border.

a little to far
LOL, just a bit too far for me to give a hand, or for my shop to work on your bike. Good luck. St.

Hansen's has my final drive right now for a reseal. They've had it a while, as they are making new tooling for all the special Airhead jobs after losing everything in a fire in September 2020. I spoke to Craig a few days ago and they now have new fixtures for the job.
For a lot of the Airhead stuff, they're using this as an opportunity to build better fixtures. For something as simple as the drive cup (splines) on the rear wheel, it seems the old tool took two mechanics to run it. Three if using hot rivets. The new tool is a one-man item.
