Title: G-Scale Trolley motor brushes and springs
Post by: BillC on March 14, 2024, 12:48:58 PM
I am looking for replacement brushes and springs for the Trolley motor. Any ideas where I can find them? Is this the same motor assembly as some of the HO motor assemblies?

I think so, but the brush assemblies are a little different. They tend to melt, so you have to do some fettlin' to make them fit. Check out this thread:

The problem is the convoluted way the brushes connect to the pickups. This pic shows you the differences.

Fred, thanks for the info and the link, very informative. I was actually attempting to do what PeterT (in the link) doing. I have another HO motor I am using the brush cap from and will adapt it. Looks like I may need to use the armature also as the trolley armature has melted plastic all over it (the brush cap as severely melted around one brush. I am going to try to pop the brush holders out of the HO brush cap (I have already popped them from the trolley's) and see if I can put the brush holders from the trolley into the HO brush cap. This will keep the bizarre brush connections intact.
