Pinion removal from humpback motor

Not sure if this query belongs here or under tinplate

Need to remove the armature from a Lionel 156 Humpback motor and that means removing the pinion from the armature shaft. The ears on my wheel puller are too thick to fit between the rear of the pinion and motor frame so am hoping someone who has faced this issue before can offer a workable solution. Have seen a few youtube videos where heat is first applied to the pinion and then it is gently pried off the shaft. Is this a reasonable thing to try?

Thank you, swede

I don't have your answer but I would inquire on the TINPLATE TRAINS forum.
