Are you referring to the plug or the locating bolt?

The plugs thread depends on the crank;

If 2 plugs then it is 7/8 x 11 tpi BSF.

If only one plug in then it is 7/8 x 20 tpi. I think UNF or Cycle not sure which.

The change happened around October 1964 according tothe Service bulletins.

Great fun getting them out, two hours or two minutes if you are lucky. Some make up a home made tool for this job. Just bought a brand sludge tube from Kidderminster M/C's. Good luck  ;D

One of mine (A10J came out easily. To get the other out I drilled a hole in it and used a good quality screw extractor. Came out nicely then.

I've never taken both out as the tube comes out of one end and you flush it out from there surely? Mind you, it was 12 years ago that I last took one out. One of the benefits is the new plugs have a socket head not that pathetic slot, so next time will be much easier.
