Im not sure exactly because my buddy just gave it to me but I think its a 2 gallon tank and 150 psi

 

I was reading about it being a bad diaphram so I took it apart and seen that it has like metal diaphrams in it which I thought was strange so I cleaned them off and put them back in. How can I tell if their out of adjustment?

 

The metal is correct. To adjust it you have to tighten it or loosen it depending on the tone. If I'm not mistaken the a high pitch indicates it is tight. And obviously low pitch is loose. The air sound you heard is probably it being too tight. You adjust the tone by how tight the whole diaphram is against the trumpet.

 

Honestly though if this is a real pulled off a train train horn it is to loud. Now if it is just a set of trumpets off a big rig I say its ok. The amount of air you have should be enough for a few seconds of honking.

 

Do you have A picture of the horns?

 

Go to youtube and search train horn prank.

 

Well when I took them apart i did notice that they were loose and when I was done I tightened them all the way down so that could be my issue.

 

never uploaded a pic before lets see if it worked lol

 

You don't want it as tight as you can make it. The pedestal keeps it from moving. You might have to twist the horn to adjust where the pedestal is. But the pedestal has to be tight against the diaphram because that's how it gets the air.

 

Buddy of mine got $500 worth of tickets for using his train horn on a college campus around a crowd of people. Just be mindful where you use it, cops don't think they are very funny.

 

Thanks for the advice. I probably wont even use it much, when my horn did work I never used it but it just seems like now that I cant honk at these people driving like idiots on the road it makes me want to more lol I guess I couldnt appreciate having a horn untill ive been without it

 

So I want the bolts holding the horns to the pedestal as tight as I can get them and loosen up the screws on the back and it should work?

 

Train horns are LOUD...worked on the rails for 6 years in Vegas!! Like others have said be careful on when you use said horn,if there are people in near vicinity you could actually cause damage to their hearing! You tube videos make it seem as though cruise ship horns are LOOUUDD...lol..either way enjoy but be careful!!

 

The trumpet threads into the pedestal, then the diaphram threads onto the back of the trumpet, correct

 

You got a nice setup for free. But, they are not train horns. They are truck horns. Make sure your tank is full before trying them. They use a lot of air volume. I would hook to home compressor to test them.
