Hi all, new to the forum and to model trains.I bought a used Santa Fe 8352 Diesel Engine, which was not working. I took apart and cleaned the motor and armature. I was able to clean the copper armature, brushes, and e unit and I was able to get it to move and fire the lights up. However, the vertical engine on forward will only drive 12-14 inches and the motor seems to pop out of gear and revs on high without the train moving anymore. It seems a little better in reverse however does the same after a loop around the track. This is also without pulling any cars. It seems as if the worm gear is popping out of gear. The power truck is stamped "8250-125".I noticed that the plastic gear that the drive shaft is attached to also slips and has fallen out. I have pushed this back on.I tried screwing down the set drew on the plastic brush plate but this did not work. There is no other washers or bearings to adjust or replace.Any ideas?Can I rebuild this unit or just look for a new/used power truck to replace this one.I tried attaching pics but the website says the server is full.Thanks for any information.
