I have the OEM IH horns (with the logos) made by Grover. Parts are still available as far as I know.

A picture is worth a thousand words.
My guess is there's no fix to the die cast pot metal diaphragm retainer. Is it a Bendix? I have parts for some of those.

Grover has some nice horns. http://airhorns.com/products.aspx?category=truck



Tony,
My truck is out of my yard for about a week due to having some mechanical work on it. When it comes back, I'll take a picture. Original horns with IH logo. Not sure of the manufacturer.

The Grover horns don't have air on the cap side where the screws are,the air is on the horn side of the diaphram,there is a gasket between the mounting pedestal and the screw down head,also they need to be tuned.

Any one ever restore old air horns? I took mine apart this summer and cleaned them. I put them back together and there are a few cracks in the rear screw plates. I started up my truck yesterday after finishing some ceiling work and the air horns sound worse than they did before I cleaned them out. I can hear air leaking out of the cracks. What would I use to seal the cracks? Silicone? Would finding new plates help or maybe replacing the air horns in general. I found some air horns made by Wolo that look like they might fit with the mounting style that my truck has on the roof. I would rather fix them if I can instead of replacing.
