Klaxon horn repair

These are the original vintage horns of the twenties to thirties era. Robert Bruce, Queensland. I can get your old horns working! Klaxon or ah-oooh-gah horns can be purchased new various places.


You do need to tune them by adjusting a screw with a nut on the diaphragm. It took me several attempts to get it right.

OK, since i am blasting and paint parts I have completed most of the small general components for the engine. Horn , Generator, Starter, etc. We think the best place. Using the right tools will make your horns work perfect! It was a bit worse for wear so I decided to give it a basic restoration.

Fixing a broken car horn can often be a do-it-yourself project. They go thru a metal frame and are held in place and insulated by red plastic around each contact. I believe the grouping was Shade Tree Mechanic or something like that. You may have to dance around the site to watch them in order, but it is worth it.


Unscrew the screws that hold the two halves of the case together. Carefully separate the two halves. There is a simple coil and reed vibrator. I took it apart and everything seemed good except the large wheel spun freely. Is it supposed to be pinned somehow to the brass sprocket?


To remove the wire connector, press down on the lower end of the connector and then pull the wiring out. Remove the mounting bolt and the spade lugs, which are attached to the wiring. Clean the components and then reattach them.


Ask your helper to honk the horn again. Taken apart, cleane put WD-where appropriate, repaint the case, adjust the vibration for loudest tone. You could try an old time clock repair guy, the guts are similar, gear, hub bushing, and coil spring.


Very useful guy and website. I bought a new coil for mine. When dismantling the horn remove all of the studs.

I had a couple of gaskets each side. I used the Klaxon horn as an example, but the what I wrote above applies to all diaphragm type horns. I have both 6V Klaxons (for fun) and 6V goose type horns (for authenticity) on my 'Model T's, having found that, virtually everyone, prefers to hear the Klaxon , as they incorrectly associate this horn with the Model T era, even though it was.


The studs are BA size.
