A little help

What is the best/easiest way to quarter drivers? The wheels came off my 0-4-0 switcher during some repairs and I need to re-mount them for smooth running. Not being a steam buff, any suggestions would be appreciated.

Thanks

Thanks art. It’s my first loco so there is sentimental value. The problem occured when I converted it to DCC. It does have directional lighting now instead of painted white dots. :slight_smile:
