not many torque settings in any bsa a10 manual i ve read. just do up tight and peen over the locktab. i calibrate my torque wrench lifting 3 pints of ale sunday lunchtime and a throw of the dart.

Assuming it's about 16" from your elbow to where you grip the mug, one pint will only calibrate your instrument for 2 ft-lb. Better switch to pitchers.

if pitchers is a cider richard i m a great fan, but if your getting technical on me ? remember there is always the copper hammer on the spanner technique for f***ing tight.

I don't know whether I would call them sprocket nuts, Bill.
If the nuts come adrift, the wheel will fall off but the sprocket will remain.

well I wouldn't advice riding with the nuts (whatever they are) slack as you'd chew up the studs, throw the chain and probably come off,  *sad2* the rear wheel would however still be where it's supposed to be.
proviso - are we still talking A10 S/A, I'm not familiar with other A's but believe they mostly have the same set up (through axle with nut on each end)

I will be mounting the sprocket on my '57 A7 Ariel hubs soon. I am now going to start searching reference material for the specific factory-recommended torque. I'll get back to you when I find it..........

........Well, it's the year 2525 and I'm somehow still alive and still haven't found that darned torque value. I guess I'll just make 'em tight by feel or use a generic torque for 7/16-14 nuts. >:D *smile*

ramp up those 5/16" nuts up with an air gun richard [just joking ].
from my experience air guns are banned in a lot of places as the guns wear and loose their torque .also its been known historically for fitters using air guns until the pressure in the air tanks drop to empty because someone has forgotten to switch the compressor on in the morning.blocked filters and dodgy regulators another worry. much safer to calibrate and torque tighten then paint mark. also easier to sleep at night when the vehicle is carrying passengers.
i m not aware of any torque values on the a10 given by bsa but they did give torque values to the a65 which should be comparable.

If it wasn't obvious, I was joking about looking for torque values. I've known for years that none exist for A7's or A10's.

From my experience, the wheel nuts will make so much noise and vibration rubbing against the swinging arm you will have to stop to tighten them.  Guess how I know!
