throttle cable adjuster spanner size (2017)

SteveBorland · Sep 13, 2017

Just thinking here that it would be good to find a spanner that fits better than what I have been using, but I'm unable to find any info on this.
Other than an adjustable spanner, what are people using for this?

A 7mm open spanner works good for me not sure what small size fits in AF as I can't find my small AF spanner I know I have one somewhere in my shed but the 7mm fits good.

9/32" AF for the carb top adjuster and 5/16" AF for the locknut.

The inline adjusters may not be the same, for instance, my Mk3's inline choke cable adjuster and locknut are both 11/32" AF.
The Venhill cable upper throttle adjuster is 5/16" AF and the locknut seems to be 29/64" [Correction: 25/64"] AF (as I don't have a spanner that size) but I suppose they could be metric?

I tried a 9mm and 10mm on mine, and neither fit. My nice 3/8 wrench doesnt fit, but a cheap ass Indian spanner is a very snug fit. 23/64 would be too big I think, more like 25/64 since 10mm is too big. But that is a real oddball size. Even for a Norton. None of my WW or BSW wrenches fit either.

Yes, sorry, 29/64" was a typo, it should be 25/64". 10mm will do, but it is loose.

LOL Typo central. At least in NZ I can blame it on whiskey at this time of night...

9/32" = 7.14mm
5/16" = 7.94mm
11/32" = 8,73mm
25/64" = 9,92mm
So since no mm spanners fits properly, we'll just have to buy the correct tools....

Grind or file an under size one to fit and keep it just for that purpose.

If the locknut is loosened with a 5/16 wrench then it should be possible to twiddle the cable adjuster
with just your fingers. No wrench needed.

I remembered this thread for some reason out of the depths of my mind (dont ask) and as I just found a full set of BA wrenches I decided to give them a try and a 3BA fits the adjuster.

3BA = .282 inches = 7.16mm

9/32" would likely work too, but I dont have one of those.
