Maybe I misunderstood, but here is the link for the 252 motor parts list on the Olsen's Toy website (http://pictures.olsenstoy.com/searchcd31.htm?itm=769). I'll search today for a picture breakdown of the actual motor. I thought I had one. I sold my 252 several years ago. Another person to contact is Gary Scheindili. He regularly restores and offers on Ebay prewar items. He is very knowledgeable and helpful. In fact, he has a restored 252 up for auction on Ebay right now (http://cgi.ebay.com/Lionel-prewar-252-Orange-T-Cotta-Brass-Loco-Beauty_W0QQitemZ180098105707QQcategoryZ4145QQssPageNameZWDVWQQrdZ1QQcmdZViewItem). Hope this helps.
Denny,
I think that the gear is part of the wheel. Personally, I wouldn't try to fix the brushplate. I don't think it is worth taking the chance of the repair necking down the armature shaft. Call Jeff at The Train Tender, I am sure he can help. He is the only person I buy parts from now.
