What is this tool in our toolbag for?
« on: May 20, 2023, 07:29:02 AM »
Partslist says: BAR B, HANDLE. PN: 99005-02000. What is it for? Is that 'B' maybe a misread '8' in an older document? Width is 8mm.

There has been much discussion about that tool from tappet adjuster(too big) to spoke nipple key(bad fit) but basically its a tee bar for the plug socket

If it is 8mm, then there are quite a few things it can fit as well....

I vaguely remember the discussion in the international forum and also that there was no definitive answer.

Nope, it's too big for the holes in my OEM plug socket.
Question: did early CB500 models ever come with a brake bleeder 8mm head instead of the 7mm on ours?

What a wonderful question. I've often wondered the same. I doubt it's in there as a T for the plug socket, I always use the screwdriver attachment.

Old Triumph toolkits have a tool almost exactly the same which is for tappet adjustment.  It also has a tyre lever with a square cutout on one end which is for the wheel spokes.

Obviously a plug socket bar, with 8mm jaws added on - probably to adjust the throttle cable adjuster barrel which is about the only 8mm piece on the bike. (talking CB750 in this case)

Again... it's bigger than the holes in the plug socket.

It's a tappet adjuster tool for a 400/4.

As far as the CB500/550s, there seems to be one place only where this tool fits perfectly and that is at the throttle cable adjusters.
