NWSL question

[Steamtrains]

I don't believe I had to remove the existing gear on the axle. If I recall correctly, the motor I ordered came with the mounting bracket attached, and the worm gear was compatible with the driving gear on the axle. I only had to shim the motor a bit to prevent the worm gear from meshing too tightly into the axle gear.

It was a "drop-in" installation, you might say...
