Hi.
Are the Atlas rear chain adjusters fit on the Norton Featherbed swinging arm the same fot P11?.
Thank you.

Hi Piero,

the adjuster don't fit because they have a 1/4 inch size thread. P11s have a 5/16-26 BSC thread.

Overall lenght is 44,5 mm. The cylindrical part is 7,9 mm dia and 4 mm long. The hexagon part is 6,5 mm long and 11,2 mm across flats. That seems to be a 1/4 inch BSF hex which is 0,445 inch across flats. The nuts are 5/16 BSC with small hex.

Hope this helps.

The Atlas swing arm is Norton featherbed
The P11 swing arm is from the Matchless G85, hence the different adjusters
