BSA Spanner - use?
« on: 29.11. 2019 22:22 »
Hi,
After rummaging through my bits n'pieces I came across this BSA spanner (of sorts) - one end has 2 different sizes (2 photos attached).  So I guess it has a specific use.  Hopefully a more knowledgeable member may be able to shed some light on this.  Also if any member is interesting in purchasing it, please PM me.
Cheers,
 RoadRunner

Well, I can remember using the same style of spanner on my pushbike.

Yes, I think those spanners are for BSA bicycles. Might have some uses on a motorbike.

that spanner is very good for the rocker box nuts at the front under the head, oh and anything else it fits *whistle*

  This fits most nuts and bolts on the bike. The jaws fit CEI fastenings, and are typical of a multi size toolkit spanner, handy for simple roadside repairs, not for major dismantling. As BSA started in bicycle manufacture, using the standard Cycle Engineers' Institute Threads for most fastenings, retaining this thread  on the motorcycles, this type of spanner was also commonly  found in bicycle tool kits before the introduction of the cheap stamped out sheet metal version. These days it is rare to find one that's a close fit, as most have had use and abuse over the years. 

 Nice to know to find they made one to match mine, and the Forum Caretaker also has one, featured along with the keyboard.

I have couple of those spanners somewhere in the garage had them for over 20 years was told they are for adjusting valve clearances  I think that square opening at one end fits the adjusters, never tried  them.

Cheers BikerBob,
That seems logical given the short length of spanner. And thanks for all the replies guys.

crikey guys, assumed this would have been easily nailed, its part of your tool kit for the B series.

A good rider periodically checks all nuts and bolts with a spanner to see that they are tight - Instruction Manual for BSA B series, p46, para 2.

Hi All,
The same design 4 way spanner was also made or supplied by Chater Lea
I do not have any details of their motorcycle tool kit but I am assuming supplied with cycle tool kits ??

Thanks for all your replies guys.  I've now sold my only BSA so surplus to requirements hence it's up for grabs if anyone wants to add it to their tool role?

Cheers
