How to repair a PW 6220

I have about 60 million issues of OGR and CTT in piles on shelves. I am looking for an article in one of these mags about repairing a 6220/622 bell ringing switcher. (just got on on the bay that will need lots of TLC) I believe it was an older issue of CTT. Anyone have any info out there as to what issue it was, what was on the cover, etc… I thought I would ask you guys before going through the process of looking through each one. Thanks!

What seems to be the problem?

If you ask here, you will likely get the info you need if there is something wrong with your loco - routine or otherwise.

There’s an online index of train magazine articles. Type “mrmag” into your search bar and it should take you right there. Really a great resource!
