A10 hub ?
« on: 21 May, 2018, 16:32:55 »
I am rebuilding a Triumph Metisse and have, as a start, a half done job. The hubs are BSA and I think the front is A10 (serial number inside is 67-5554). I need to match this to a spindle that will fit the Ceriani forks. I may need to make a new spindle on my lathe. Is there a diagram on the basics of the knock through spindle ? - which surfaces need to mate - presumably spindle spacer and bearing inner ?. I will need to make all the spacers too.

I think the picture shows your hub. As can be seen, both bearings are retained on the inside by a shoulder on either side of the hub tunnel, and on the outside by locking rings. The push through spindle has a shoulder on it which tightens the bearing and brake plate against the fork leg when the spindle is tightened.

The picture came from a B34 Goldstar owners instruction book.

Just checked again and it came from the Goldstar Maintenance Manual.
