@Robbin posted:Hi Folks, I have a brass Williams J that I want to convert to Lionel Odyssey. I had emailed Electric Railroad and gotten the recommendation of the Cruise Commander and Railsounds Commander Kit. I had no knowledge of the motor issue you all are discussing here. I see the Pittman 12v motors offered by Lionel. I am willing to buy the motor directly and replace what is in the engine. Has anyone done this replacement along with the ERR boards as well? Any advice?
Thanks!!
A Cruise Commander will work with either motor. Before ordering a Pittman, check how much room you have in the engine behind the existing motor. A Pittman 9433 is close to the same length as the existing Mabuchi but a 9434 is about 5 mm longer. Lionel pictures the 12 and 15v motors so you can read each model. Rather than pick a motor by voltage pick it by size. If you have room for a 9434 then it obviously doesn’t matter which one you pick. There is little performance difference between the two voltage ratings. Maybe a bit more low end torque with a 12 v.
