I used several solid hub disks 35 or 40 years ago. Problem was that the rebuilders put on new linings but forgot to drill out the holes and use oversize rivets to fasten the hubs .
The holes for the revits are usually "oblong" after so much use. At least the that is how the ones I tried years ago were. The result is the hub moves around, chatters and finally breaks off the rivets. Clue of pending failure is that after running them a short time, you will see rust "dust" (closely related to "surface rust" I have been told ![]() Last edited by Benson; 05-25-2012 at 10:42 AM. |

The clutch disk shown in post number 6 by Bogdonj is what most Model A suppliers today are selling. However, I have seen several of these fail due to one of the springs dislodging from a mounting slot and jamming the clutch. The springs are not held in place by much, they look to be held in place only by their own tension. You can easily knock one out with a nominal tap with a small hammer.
Years ago there was a company called Nova that made a superior clutch. However, they are no longer in business. The attached photo here shows one. Note that there is a flange around each spring. There are also flanges on the back side. The flanges will prevent the springs from dislodging. I have picked up several Nova clutch disks at swap meets for a few dollars and bead blasted them and measured the thickness. If they are not soaked in oil and the thickness is within spec they are good to use. One has been in my Victoria for at least 10,000 miles. Recently I noticed a fellow club member bought a new clutch disk from Bratton and it was made similar to the Nova clutch with the spring retainer flanges. I don't know who the mfg is, but I would certainly go that route if I was in need of a new clutch disk. Tom Endy |
