Well, one of my projects that took about 3 months with parts delivery and exchange of gear boxes was to take out the C&LS drive which has a 36volt motor and put in a 12 volt motor with a new gear transfer system. This provides much, much better low speed performance and torque, allowing the engines to start a train and avoiding jack rabbit starts. You have to bring your model's frame down to the bare essentials. You can leave the trucks in place.
Here we have the factory installation. It has a flywheel and an unmarked Pittman motor. I worked with Jerry Criswell of Right Of Way who has developed this following system for repowering the models.
This view shows the C&LS gearbox removed as it will be modified with ball bearings. The motor will be disassembled for parts to reduce he operating voltage in a future use on another project.
Here we are awaiting the new parts. The replacement process is the same for both the RS11 and RS 12 models. My project had me nervous because I have four painted models. You can see the hood lying on its side. It has constant lighting, etc, already installed.
Here is the new drive installed. We have a modified gearbox, a gear head motor by Fulhaber and a strong, heavy base for the system.
The modified gearbox goes back onto the original mounting holes and four new mounting holes are drilled for the motor and gearhead. The wiring goes back in place. The brass plate on the gearbox contains the ball bearing.
The engine ran beautifully on the layout
It just started at a creep and went around smoothly.
One down and three to go.
Now the engine pulls as good as it looks. I was very pleased. Each engine took a full day to complete.
