replacement axle gear on SD45

[Capt. Brigg]

I have an older Bachmann HO scale SD45 with the white axle gear on a drive wheel set, that is split and slipping. The Bachmann parts department said they no longer carry that axle gear but perhaps someone here has a gear or a suggestion how to fix the problem. Is it possible the axle gear on a newer model engine could replace the SD45 gear? Any suggestions will be greatly appreciated.
