There is a little brass bushing in the flyweel whose sole purpose is to
support the felt dust seal. Those bushings get knocked out at the machine
shop and don't get put back in. With no support, the felt dust seal fails
over time and dirt or clutch dust gets in and destroys the bearing.
This dust seal arrangement is wonky at best but has seemed to work over
time. However, I would prefer to go the seal bearing route myself.
If you want to stick with the original arrangement, know that the last time
I had to deal with this issue, the brass/bronze bushing was NLA. Check on
The Samba!
