horn repair

can anyone tell me if a 55 to 57 horn can be taken apart and repaired

The 55 56 horns havea bell shaped cover that comes off and inside you find a set of contacts. The contacts can get dirty/rusty and stop the horn from working. Slide a piece of 320 wet or dry sand paper thru the contacts several times and they usually come to life. I may be wrong, but I think the 57 horns are sealed and not serviceable?

I found a few horns in my trunk...I might be willing to take one apart to check it out if you tell me which ones you have so I can see if I have the same ones.

The 1955 Chevrolet Passenger Car Shop Manual, page 12-12 describes the method of adjusting the horns.
And... there is a horn relay (mounted near the voltage regulator on a '56) to check and adjust as well if both horns are not working.
I took one of my horns that wasn't working apart and cleaned and adjusted it and it works great now.

These horns do get peoples attention.
They sound much better and louder than new cars.

In the olden days I bought 6V horns from early 50's cars. When they get 12V they sound like air blast. Last a long time as long as you don't hold the button down.

theres a fella i know who has a pair of horns he wants to get rid of that didnt work, they look good on the outside but wouldnt sound , and i wasnt sure if they would come apart, the only thing is if i get them going he may want to bump the price of the horns up, kinda catch 22 here, i dont mind paying a fair price but if i get them going i dont think i should pay him more for doing the work.

sorry forgot the year their 56 horns.

I don't get it ... if you buy them and then fix them, he can't charge any more, right?

Sounds like Mr Hanney from Green Acres :cool:

I also have a pair of horns from a 57 (high and low) that did not work. I bought them used, and was told they didn't work. After vacuuming out many of the insects that had made a home inside them (wasps) I got one of them to blow...but it sounds a little weak. I would also be curious to know if the 57 horns can be taken apart and rebuilt, or at least cleaned out better. If so, who does this type of work. Does anyone out there know?

I also have a pair of 57 horns that don't work. I bought them used, and was told they didn't work, but after I vacuumed out the bugs from them, I got one to work. I would also like to know from anyone out there, if the 57 horns can be opened up and cleaned/repaired. I have seen at least one ad for 57 horns ($200 pair) and I believe they are rebuilt. If so, it would suggest that they can be serviced. Does anyone know for sure?????
