I am trying to remove the nut that holds the plate that the drive shaft bolts to on the transmission of a '62 BMW R50/2. The nut is round on the outside, but has four slots cut into the top - sort of like a castle nut, but with just four slots.

The tool must be like a 4 point socket with 4 pegs sticking out at the corners. Anybody know what the proper name is for this socket/tool ? It is very hard to find if you don't know what you are asking for.

Work arounds gratefully accepted.

Thanks

Greg

Capital is still in business and probably has the tool. Ed Korn also has the tool. Actually Ed makes a nice, inexpensive set of pullers for working on the /2 motors. His transmission output nut socket is $50. A little steep for a socket that will get used once.

Honda does have a similar tool for their clutch basket. I even have one, but it is too big for this nut. I was hoping that this would be a specialty socket that could be bought over the counter.

Ive never done that job but you sound like you are winging it without the service manual.There are two other service tools you may need to do that job.I rebuilt a 1977 motor in 1978 [1000 cc] it had a rod seized to the crank.Ill take a Harley anyday over those sideways shakers.No offense and good luck.

Thanks for the good wishes. Actually, I have the service manual and the parts book. I am trying to wing it without investing in $500 worth of specialty tools. It's a long story. I'm doing as a favor for a guy who wants to get the bike going for a friend of his as a surprise. Both of them are customers of mine, neither of them are mechanics...

The BMW is a nice bike, but I'll take my Norton over it every day. I wouldn't mind one of those Buell XB900s.

That nut is designed to keep "shade tree mechanics" out of the works, and so you have to take the car to the dealer to have it repaired!

The nut is called a spindle nut, and they are usually used with a "French Lock " underneath . one of the tabs of the lock is bent into a slot on the nut to keep it from backing off.

It looks like the Honda clutch nut socket, any idea on the 'official' name of this tool ? The one I need has a 15 mm ID.
