Removing Cassette Deck Capstan Motor Pulley

[Sofa Slug]

I need to replace a dead capstan motor on a Nakamichi "Cassette Deck 2".
Apparently they are no longer available in stock form, but I may be
able to use a generic capstan motor.

The only problem is that I would have to remove the belt pulley from the
old motor shaft and press fit it onto the new one. Is this possible to
do without ruining the new motor? (I have an arbor press.)

-Thanks

Heat the pully. the brass will heat much quicker then the steel shaft.

Thanks for the info. How do you press fit the pulley onto the new motor
shaft without damaging the motor bearing?
