Tandberg 3600xd the motor's front bearing

Hello everybody,
more than month I try to fix/repair the front bearing of Tandberg 3600xd. The bearing stays very loosed in his bed in the front bracket.This cause the rotor goes very close even touch the stator of the motor. Sometimes it runs with noise sometimes it stops making Mmmmm...noise.
I post this problem with TH ,but still I don't have a answer.
Is there somebody with experience of this matter? Is the epoxy is good material to fix the bearing in the bed of the bracket? I can shim the rotor equally in stator,and than attach the brackets and use epoxy/lock tide or similar material.
I don't want to risk,and I'll wait for some better idea from you.
Thank you in advance.
