FINALLY I got motivated to get back to work on this project. Got the boiler off easily using TOC’s instructions as posted on Greg’s website. Changed out the drive axle and gear using excellent instructions written by Mik. Opened up the gear-box to check the motor screws. They had Red Loctite, but I re-did them with Blue.
Lastly I did a quick temporary hook up of a Railboss Plus and ran siome operational tests. So much smoother than it ever was on track power!
