Athearn C44-9W Northwest Short Line Motor Installation
The C44-9W project continues.... I understand why I got this locomotive for very cheap. This project was abandoned due to a lot of technical problems. The previous owner almost got it to work, but several faults cropped up making this a very frustrating project.
The drive couplings all have at least 1 pin sheared off. This was a likely attempt to get smoother operating characteristics that ultimately lead to the couplings coming apart frequently.
I've change the position of the couplings and used a drop of super glue to hold them. Most people aren't comfortable doing that in case there is a screw up, but if you use a tiny screwdriver and hit just one side of the shaft, you can remove it later if you need to.
I use Goop to hold the motor in place. It does a very good job at cutting vibrations and can be removed if I make a mistake.
