Model T Ford Forum: Forum 2016: Cleaning a horn motor
Top of pagePrevious messageNext messageBottom of page Link to this message  By JohnCodman on Saturday, August 20, 2016 - 09:42 am:

The horn on my '27 sounds like an anemic Frog (when it decides to work at all). I have taken it apart and it's full of oil and crud. The horn is made by E. A. Laboratories of Brooklyn, NY. What can I use to clean the armature and brushes? I'm tempted to use spray carburetor cleaner, but I don't want to hurt the brushes or any insulation.
Ideas?

Hi John,

I have used carb and/or brake cleaner on horn motors with no problems resulting. Good luck with your project. Bill

I would use electrical cleaner. It's made for cleaning contacts and motor windings etc. It should be in the same area in your parts store. Do not use lacquer thinner it will remove the varnish from the wires in the armature.

I like this stuff on electrical parts, but be warned use it outside, it does have a powerful odor:-)

Thanks to all who responded. I think that I will head to Wally World this PM and see if they have the CRC Electrical cleaner in stock. If not, I'll use carb cleaner

Both cleaners will strip the oil out of the bushings so remember to let the cleaner evaporate and then re-lubricate them.

Carb cleaner may effect the lacquer insulation on the motor, I would NOT recommend its use!!

TV and radio tube cleaner works great
