Thanks. That kinda confirms the motor is directly inline with the Motor. Where’s Whipping Boy when you need Him? Should we say Shubin rings once more? Sound’s very typical of a Mazak style shaft to shaft coupling.
Your problem with inserting the spindle up into the coupling probably wasn’t so much to do with the rust. (Although it shouldn’t have been there), its because your pushing into the lock ring, the way they are compressed to bite the shaft. Much better to drop them right off, and bring them up into the coupling hub, after the spindle housing is at the correct height. I’m not sure about that ceramic cage thing.
Your little problem, with posting. You just have to scroll down in the little box, provided for replying. Or just keep typing, it will move down automatically. The size of the box, isn’t the limit, to what you can type here. Or write your stuff in a word processor program like word, or note pad, then cut & paste the whole shebang into that reply box. Regardless, Welcome aboard.

I’d be betting a bottle of Kentucky’s finest, that your problem, is to do with alignment of the motor to spindle. 1 machine out of 4 chewing spindles. The spindle keeps getting replaced, but the motor and coupling sit in place, never being touched.
Those couplings have 6 tensioning screws to lock them. Unless they are torque’d up in order. You can pull a big deflection resulting in run-out of the coupling. You need to have checked, the runout of the coupling, prior to installing the spindle. The motor registration journal also needs to be checked for run-out. You would need to lift the motor for this, to dial off the spindle into the motor location journal.
