Title: socket for stanchion top nut and oil tank nut
Post by: Scott and Jay on 29.10. 2024 02:44
Hi, Scott here
I know the tool I'm supposed to get is part 61-3001. This is meant to do both the above purposes. However, the oil tank nut is recessed, and I'd prefer to have a socket. That should do both. What socket and where might I buy one, please?
Kind regards, Scott

If you measure across the flats and then look at the link contained here https://www.a7a10.net/forum/index.php?topic=17883.0 it should be possible to identify the weapon needed and then find someone happy to take your money online.
(OTOH, many here probably know the size off the top of their heads and will chime in  . . . my memory is fuzzy  but I know I used a standard socket or cranked ring on my B and my A, no problem . . .)

I use the nearest metric (30mm, 32mm? can't remember!) However, because of the way sockets are made, with a chamfer on the inside to assist easy engagement with a big nut, the socket will slip on the fork nuts because they are very shallow. The socket I use (still can't remember the size!) I've skimmed the face to remove the chamfer so it reaches down the full side of the fork top nut.

The imperial size is 3/4" Whitworth. In the UK they turn up at autojumbles or Ebay

I look for old Whit sockets at auto jumbles and boot sales as no one wants them.  If you need it now a box spanner is another option as it fits in the recess.

Thought 3/4BSW 'cos mine has its chamfer turned off to get full contact - I now know why I did it!

I use a 33mm Pro Tools deep socket.

The sockets are still available new. I bought one recently

Yup. And 33mm is 1.3" AF to a very small gnat's wotsit,  and 1.3" is 3/4W, so whichever is easier/cheaper to find.

I haven't ground off the chamfer on my 3/4W socket, but I do make sure the socket is very firmly held down with one hand when loosening and tightening fork nuts.  Haven't had a problem so far, but if you do slip under load you could lose some paint somewhere.  I remember a few moons ago having a large-ish socket fall off the ratchet over the tank - nice little chip for 'patina'. *pull hair out* *pull hair out* *bash* *angry* *angry* *problem*
