I'm trying to rebuild an older 0-6-0 switcher ( slope back tender) model number ( item 50601 )
On each on the axles - there is a nylon part with square holes in reach end - where the  wheels insert. The Nylon part  insulates the DC+ ( engineers side ) from DC- Fireman's side   keeping the wheels isolated.. Two of the nylon parts are only cylindrical - and the center nylon spacer also has the drive gear.. My nylon parts are cracked and the loco won't hold wheel width spacing.. If I can buy the parts - Great.. Alternate is super glue to hold the wheels onto the spacers .. any other thoughts on adhesive??...Any other thoughts.. .. Thinking of drilling and pinning too
I know I could just buy another.. but I'm a retired engineer with too much time on my hands.. Thanks John

I have a new Bachman 4-4-0 - and i can't change the decoder.. My club uses NCE power pro.. tried to change to # 26.. and decoder would not accept - had to toggle " reset to factory to get back to # 3
So how do I accomplish the  decoder re-address??   Thanks

I have the nice 4-4-0 running fine - with address # 3 ( default).. While at the club, we tried to change to Address 26  using NCE power pro - both " on the main" and on a programming track
Loco would not accept - and we had to toggle CV8 ( i believe) to reset to factory..
Can anyons suggest the correct procedure for changing??
