Which tool are you using to take the grub screw out of the brass spindle to remove the motor? I am trying various small screw driver but none seem to bite. One did wok on the other grub screw on the cam nut.
Be sure to measure the distance between the spindle and the metal plate above before unscrewing it. I have noted a lot of comments in other threads that the distance shown in the service manual is not correct, so better to make it the same as it was.
