The can on one of my 63100s seems to have slipped a bit on the shaft, creating some play in the motor.
Is there actually a set screw at the bottom under this blue plastic? Just dont want to keep drilling and drilling through it.
Yes but only on one of the 2 sides with the blue stuff. My grub screw also was loose a while ago so i drilled down one side only to find out that it’s a dead end. Drilled through the other side and got through.
