I picked up a free ek43, I believe it’s a 2001 based on the 01/09 on the tag.

It was a bulk grinder at a roaster for many years and is in quite rough shape, I completely dismantled it including motor frame (yes I know they warn against this). I cleaned about a pound of coffee out of the rotor and motor frame.

Does anyone have any tips for front and rear bearing removal? The back one has a bit of noise to it so I figured I may as well replace all three.

Also I’ve seen polished metal grind adjustment knobs but can’t seams to find a link to them.
