Does anybody have any tips/tricks/knowledge on the removal/reinstallation of a middle drive wheel on a MTH PRR M1A Mountain Railking edition. I stripped out one of the middle drive wheel-linkage connection points. i have found a replacement screw/linkage (due to my kids running the train off the elevated section of my layout last year and damaging the linkage. I went to straighten out the bent linkage and reinstall and upon reinstalling, i stripped out the drive wheel screw mount. This is by far my favorite engine and i would like to get it fixed before next christmas so if anybody has any ideas/tips it will be much appreciated

I would not start by pulling the wheel.  Remember, you have to get it back on quartered correctly or you'll have more issues.

You can repair the thread with a Helical Insert.  You can also fill the hole with something like JB-Weld and then drill and tap the correct threads again.

Sounds good to me, i was thinking of going this route if i couldnt pull the wheel. i may try this first and see how it goes. thanks for the suggestion
