VPI Platter Spinning SLOWLY


I've tried two different lubricants (Super Lube and Shimano Dura Ace Grease) for my VPI Classic 2 platter and it still does not spin properly. I removed and re-applied grease and it spins fine for about 5 minutes, then it slows down immensely. If I remove/re-install the platter, it spins smoothly again but only for a short period of time. Anyone experience this before and know a fix? Thanks

You do not need to lube the shaft, the bearing inserts are made out of self lubricating material.
Check plastic pulley on the motor. There should be a small Allen wrench site on the side. Make sure it is tight.

What is your method for pulling the bearing out to access the well?

Thank you all for the suggestions.
