Sunbeam S7D stud
« on: January 07, 2025, 06:36:15 PM »
Anyone know what size stud holds the rear Hardy-Spicer joint to the rear drive unit?
Thanks.

In that pic, on the left side, you can see end of them at about the 1 and 7 positions.   There are 4 of them and they attach the Hardy Spicer to the flange coupling for the rear drive unit.

What do you have of them at present.
Wouldn't there be holes that would dictate their size ?

And wouldn't Stewart Engineering have what ye need.
Or have they ceased ...

From memory I would guess at 5/16 BSF or possibly BSCy, but it's been a while..
Do you not have any spare fasteners you could use to ascertain the size?

Stewart engineering does still sell them for 9 pounds each.  Hoping for something more generic, but I bit the bullet bought one.
