Typically, I remove the motor to get the broken pieces out of the antenna gear mechanism. If not, there is a chance the the new antenna mast will jam. Once the motor free of all the gear pieces, then you turn the radio on, then you feed in the mast until it stops, then you have some one turn off the radio and the motor should suck in the rest of the mast. it may take awhile to get just the right angel so the teeth mesh properly, but a few tries and you should be able to do it.
