I have an Athearn SW-7 with a funny problem. The front's trucks very front wheels won't spin! The wheels behinds the front's pair does. Gear issue maybe? Will a GP truck or parts work? I have 2 thats dismantled. " Heck with counting 'em rivets, TRAINS ARE FOR FUN! Not called the Mad Scientist for nothing either!"

Bad gears. The 2 small ones on the axles wear cracked! Got the gears were replaced from a newer pair of F-Unit truck gears. Will need the one-hole styled motor mounts. " Heck with counting 'em rivets, TRAINS ARE FOR FUN! Not called the Mad Scientist for nothing either!"
