Chuck,
Already found the $30 replacement block, but since I have the old one torn apart I thought I would see if I could replace the motor and try to reassemble it

Yesterday the grandkids burnt out the motor (RS-385SA-2073) on grandma's Durango & Silverton locomotive.  I found a replacement motor online, but it doesn't have the worm gear.  Can I remove the gear from the bad motor and install it on the new one (how)?  If not, can I get a new motor with the gear attached?

Thanks,

Bob L
