I don't like the way the big round Rivarossi motor sticks out of the back of the cab on this little 0-6-0 switcher #7641.
Have any of you used NWSL motors or others to repower this loco? I am adding details to it and thinking about using a motor that fits better.
Thanks, Dan.
Dan, all you need is to put a bigger cab on that locomotive, or maybe add some simulated canvas curtains under the roof overhang.
I've remotored lots of diesels and steamers, too, and one of the main things to take into account is the shaft size of the replacement motor in comparison to either the original motor or to with whatever the new motor will be connected.If the worm is mounted on the shaft of the original motor, you'll need a motor with a shaft of the same diameter or a way to bush it to that diameter.If the worm is on its own shaft, then you have the option of using universal joints or model airplane fuel line to connect the motor. The former may still involve disparate shaft sizes, and what you require may or may not be available. With the fuel line, shaft diameter shouldn't be an issue.
Another thing to consider is motor dimensions. Obviously, you want a motor shorter than the one you have, but it also needs to fit into the boiler both width-wise and height-wise - the latter has as much to do with aligning the motor shaft with the drive shaft as it does with fitting into the boiler's available space.I suggest that you contact Dave at NWSL, as they may have a specific motor for that particular conversion. There's also a possibilty that they may have a replacement drive train, better-suited than the original, to go with the new motor.
