Power winder chuck bearing replacement

[Keta]

Has anyone her taken apart a PacBay power winder head to replace the bearings?

i haven't, but when you figure out bearing sizes, let me know!

I had a rod that needed work and I took the bearing seals off, cleaned the bearings and reassembled it.  When the rod is finished I will take it apart to replace the bearings, I will let you know the bearing size.

The pulley is pressed on, once it was off I shaft pressed out then the bearings.  No C clip  retainer, just a tight fit.  I took the chuck apart and cleaned it and it is a lot smoother now.
