I purchased a few months ago an NW 4-8-4 82155 that runs OK. However it has a jack rabbit start and the motor wines. I am not having any problems of it staying on the track as long as I keep the turning radius above 11". The loco does not seam to have a very fast top end and the low end is not as slow as the Katos that I have.
Do I need to lub the worm gear? Bachmann tells me that it will not heart but it appears that taking apart the steam engine to get to the worm gear may be challenging. Does any one have any advice as to how to proceed? Are there any tips that would be helpful? Maybe I am trying to get more out of the steam engine than it was designed for. Should I just leave it alone?
