A local dealer had offered to sell me a recon motor for =A330. I did a
search for a new armature and found one at =A337. By the way how do I
completely remove the armature?

I found this page http://www.sparesrus.co.uk/tech/gecarmature.htm
but fail to remove the armature at the instruction point below as it
seems to be still firmly attached to the other end of the frame.

" Remove the old armature
Hold the armature by the pulley and gently tap the end frame to
release then pull it clear of the motor"
