I took the end plate off, and noticed that the bearing has a bit of fust on the outside.
possibly or probably not an issue but the bearing doesn't look as pristine as is should being sealed in a motor.
There is a side load adjuster and I can get rid of a lot of the noise by increasing the preload, and cna increase the noise by loosening the preload.
The bottom bearing also looks less than fresh so I am going to replace the bearings.
Possibly of use to someone - upper bearing NSK 6304Z, lower (output) bearing NSK 6006Z. They are commonly available.
I'll report back once I get the new bearings.
