This is my first instructable and hope it helps other with similar problems.
I bought a North-East Electric Company ahooga horn from an antique store and after taking it home I realized why it was there in the first place. It wouldn't make the ahooga sound it was more like awoowa. I took it apart and lubricated with light oil and it worked! Ahooga! But hold on why have I made this instructables? It didn't last long before it was back to awoowa. In this instructable I'll show you how to tear down an Ahooga horn .
Step 1: Tear Down
You need a ratchet or wrench and a screw driver.
Remove the bolts around the horn and take the motor cover off. Next remove the horn and the motor assembly
Step 2: Greasing
I used white lithium grease and grease the tuning screw, and the bushings. I then ran the motor but you could spin the motor by hand and then wiped the excess grease so it doesn't splatter all over the place.
Correction, after using it for awhile and with it getting cold I have found the grease is too thick and now I use a common 3 in one oil on all the parts except the diaphragm gear (use grease on that). I cleaned off the grease and applied the oil in the same spots where I greased.
Step 3: Optional
I cleaned the copper thing at the bottom of the motor because it had a sticky residue.
