Legacy Diesel Engine Racing

TTOGR Forum Member

I have a Lionel SD-60 CSX Legacy Diesel Engine. I'm running it with a Lionel 990 Command Control CAB 2. It ran fine before I covered up my layout for over the summer months. It has been sitting for 5 months. I just uncovered it yesterday and now I'm having big problems with this engine. I tried reprogramming it. It runs fine for a short distance than it takes off like a "scared" rabbit for no apparent reason??? Anyone else have this problem?? if so, what did you do to correct it??? I'm pretty much at my wits end with it and I'm about ready to pull it off the track and put a MTH on in it's place. Many Thanks for your help guys!!! TT

I have an SD70ace SP engine that my repair guy has agreed to nickname it the "engine from ****" because at first it would not even run and he stripped it down to the bare chassis to find several bad connector plugs. It ran fine for about 10 days and then doing exactly what you are describing. I took it back to him and I am waiting to hear an answer on what is going on. As soon as I hear I will let you know.

You could have a loose flywheel, bad encoder board or wiring. It might be best to take to your local repair shop.

Depending on the model, those that use an LED tach reader can get dirt and dust on the encoder causing a similar reaction. Cleaning the flywheel ring and encoder may clear this up. G
