Excessive horn vibration...

[Cal_Gary]

Hi guys,
Recently I got my horn button repaired and now have a working horn. The issue is that whenever it blows it sounds and feels like it's vibrating the whole hood. I used a pair of rubber washers as insulators but that made no difference at all. Any ideas?
Thanks,
Gary

Mine is the same way,you can hear the hood rattle when the horn blows.

Gary, I believe they are adjustable by tightening the center bolt. I have an extra one and will give it a try today and get back to you with the test results. I owned a M38A1 Jeep years ago and was able to adjust the horn that way.

I should have said the bolt at the back of the horn, sorry guys.

I tightened the bolt on my spare horn and had less vibration and noise, loosened produced much more.

Thanks Carter,
I'll check this later today.

On mine, the vibration was due to the brace/support that runs across the hood that the horn mounts to . The brace was vibrating against the hood when the horn blows. Before I painted the hood I tack welded the bracing to the hood and no more vibration. When I honk the horn now all you hear is the horn.

Thanks guys, I haven't had a chance to check on this yet, and the weather is coming in over the next 3 days....

Well I finally got to look at this the other day. I removed the hood and sure enough, there's a gap between the brace and the hood skin wide enough to fit a paint stir-stick under it. Cinching it up tight and tacking it made no difference-still too much vibration so I'm going to relocate that rascal.
More to follow,
Gary

Thanks for the info, good thread, I was able to fix mine.

I have a 2nd horn issue, when I turn my steering wheel my horn sounds and wont stop sometimes? Any tips?

There is supposed to be a piece of cork in between the brace and the hood sheet metal.

Thanks John, I didn't know anything about a cork buffer in there;

Carolina, yours could be a few things:
1. Fresh horn wire with no worn/torn insulation?
2. Is the wire retainer in the top of the steering shaft fully seated?
3. Is the contact plate correctly positioned and not upside down (it's got an indented center-at least mine does);

If all of that checks out, you might have to shave down the contact nub on the end of the wire to give you just a tad more clearance-that's how I solved my horn blowing on turns.

Gary,
Can you tell me more about 2. and 3. , im not sure I follow exactly.

[Cal_Gary]

Sure-open this link and scroll down the right side to the 24V Horn button repair kits for Types E,F, and also the horn button cable insulator.
http://vintagepowerwagons.com/pdf/parts/14steering.pdf

The kit shows the small metal contact disc under the spring next to the rubber horn button cover; the cable insulator is the next item for sale underneath and inserts into the top of the hollow steering shaft. The horn button wire seats inside the insulator with the wire "nub" down against the top of the insulator. All of those components must be in place in order for your horn to operate properly.

I will check to see if I have a picture of mine-will follow up tomorrow. (I won't pull the horn apart, however, as that rubber top cover is a "beech" to get back on).

Roger that, I will look into that.

Thank you for the info and direction on what to look at.
