tight in the center holes of the rubber (Viton?) rings. Are the rings also snug <br>
in their sockets? Or have they worn/aged so they are loose now?<br>
<br>
I wonder if those rings might have started out as O-rings, flattened in the <br>
riveting process. If so, it might be possible to buy Viton replacements. <br>
What's the OD of the rivets and the ID of the sockets?<br>
<br>
This thread makes me want to take a fresh look at a complete fan and hub, <br>
just to get a better picture of the finished assembly.<br>
<br>
Thanks for the photos. That really helps.<br>-- <br>
