GLUE inside 2500kv Eflight 180 motor!

Somehow a tiny amount of ca found its way into the motor.. I see no provisions for removing the mounting tube to expose the c-clip, or whatever holds the bell on. After soaking the motor in nail polish remover it moves freely with an occasional rough spot. I might have to open it up, but cannot see what I am getting into short of cutting the heat shrink around the mounting tube. I can find nothing on the net about shaft removal, etc. The motor is out of a UM Sbach and appears the same as the ones out of the Beast.
I will continue to soak/blow the motor, maybe get something stronger than nail polish.. Any ideas on how to open it up?

update.. running the motor with no load produces an occasional rough sound at lower rpm, smooth at high.. must be a tiny loose piece in there.. continuing to soak/blow..

update: after manually blowing the nail polish out repeatedly, I am dizzy yet successful. Motor is now smooth.
I would still like to know how to open these up if anyone wants to reply.

Hopefully you will not have damaged the insulating varnish of the windings, but you will almost certainly have removed all the lubrication from the bearings. You should avoid running the motor until you find out how to dismantle it and re-lube the bearings.
