Brushed motor rehab

[JosephS]

Do you have any guide on the fixed timing motors? I have one of the blue label yokomo stock motors that I'm interested in getting in good running condition.

How much special equipment is needed?

It really depends on the motor and what tools you have access to.

By blue label, do you mean the RC10 kit motor?

Yes. It's a kit motor.

If the comm can be cleaned up with a comm stick, I'd do that. If not, I'd knock the motor apart and cut the comm on my lathe.

The brush hoods on those aren't removable. So a good cleaning is about all you can do. A fiberglass pen is great for this.

If I were going through the trouble of disassembling it and cutting the comm, I'd probably go ahead and replace the bushings with bearings. It can be done without the tool, but the tool is much easier.

I see that in vintage times there used to be advertised motor tuning/rebuilding services. Does anyone still do that?

There is a guy on ebay, offering a rebuild service.

It doesn't state it, but I assume that means rebuildable motors. Motors like this one were generally considered as disposable, once a comm stick and new brushes didn't fix them.

Many people (including myself) have successfully rebuilt them. But there is also a chance of damaging it during disassembly (been there). I cringe every time I slam one on the counter.

Anyone remember Rotor Ron? Does he still rebuild motors? He ran ads for motor building in RCCA back in the day. He's got a website and all but I've never inquired on motor rebuilding.

I prevouly asked Rotor Ron if he still rebuilds brushed motors. Unfortunately he does not. He's only 30 minutes from my house.

Wow, thank you... now we know...

...and knowing is half the battle.
