Hello fellow forum users...
Help........have  a older  Steam  pancake  motor  4-8-4  with a   broken  (very rear) geared axle....
seems to be smoker  if helps.....tender  is   Santa Fe  3781   and   chassis  marked
PN  71029.............the hard  black plastic axle  broke  right next to the sprocket...so  impossible  
gerry rig   any  epoxy fix ..........the  metal wheels  seemed to be  pressed  into the axle....
 can  any body  check  misc.  parts in shoe box  might  be able to be compatible....??
have  good picture if needed .... can email.......

....found  similar drawing and  rear geared  axle is part of  the  drive wheel assembly  P/N  3504
similar...not exact the same....
Thanx  for reading my  post...Albert
