Its about 5 years since the last time i did this , has a better method
emerged.
First measure the position relative to deck with depth guage.
Two sheets of paper meeting under the spinner to protect deck from
direct heat.
A pair of wooden clothes peg halves pushed in the gap and a couple
more such wedges to hand.
Heat with a hot air gun , remove heat ,and alternate forced wedging in
the gap to release.

Technics player with CD not spinning when disk previously stops say
at East or W position but ok if stopped in S or N position.
Confirmed by motor ohms at these positions either about
2 ohms or 12 ohms. So a motor problem

I think this time I will try grinding down the forks of a cheap cruddy small
hub puller.
With lips just enough to get in the 0.06 inch gap , heat up
and pull off. to avoid pulling the armature out of position and the 'brush'
springs with it
