??I raised router spindle with shims on bench to align its bearing with shaper spindle and the belt location looks good. Just a visual check.
Called Felder. No known similar issues per the tech. Since, the belt runs fine flipped he suggested I use it that way for a short while and see what happens. It is interesting that it does not chew bottom rib flipped. Maybe I installed it wrong again.
Anyhow, spindle runs fine. I am happy to have a working router spindle. Updated the document in the files section. Just added couple of pics of assembled spindle, so no need to recheck it.

?Well got the top and bottom locknuts from Felder. Tried the spindle and bearings don¡¯t seem to be getting hot but I have an issue with the belt. In another thread where the issues with the spindle were discussed, it was shared that the bottom rib sheared off of the new belt I got from Felder. Well same thing happened with the new belt which was a D&D belt I bought online. I am no longer sure if the first belt was damaged due to bad install.
The belt is tight but the flex seems comparable to the std. shaper spindle. Here are 2 short videos showing how much belt flexes under ~equal pressure. Should I reduce tension on the belts. I will also call felder tomorrow.
How can I determine if there is miss alignment between spindle and motor pulley? As I write this, maybe a measurement comparison of the shaper spindle with router spindle can give me an idea.
BTW, the damaged 8 rib belts appear to run okay if I position the missing rib on top. Not sure, what would be wrong if I just use these belts.
