Hi group,
I'm building a bowser HO steam loco I got on EBAY and I've just tried out the DC-71 motor.? It makes a lot of noise that seems to come from the brushes.
When I pinch back on the brush spring to ease off the pressure, there is less noise.? Is a break-in period normal and how much will that fix the noise?
I also see some rust on the motor poles.? Might that cause some imbalance and make noise?? What's a good way to clean off the rust?
I cleaned off the commutator so it is bright and shiny.?? I gave the bearings a little oil.
Any tips?
Thanks.? Fred,
