Removing air horns and adding train horn

They haven't said anything because they were too busy clamping down at the back door when you hit the city horn button.

 

Rank sorry for taking so long, been out on road. Yeah, it's kind of pointless to put 1/2 in. Hose if the entire system doesn't support it because you'll just be cutting down air flow anyways. Keep your air horns on top, and add your own system for train whistle. This way you can design the whole thing with no restrictions.

 

I ran 5/8 line from air tank to train horn valve in cab. 5/8 line from valve to horn. It cost me 32$ for material, my factory horns still work with pull cord. Issue with pull cord is it does not allow enough air through to operate train horns properly. My horns were taking off an actual train, they have a larger valve internally which demands more air then ones bought from chrome shop.

 

Ouh man, i did it with my freightliner, so when truck be home I can share video! with sound!

Stock air lines for horn are too thin so I fit big air solenoid under hood, and used 10 mm air lines!

Really it is not legal and ones I used this horn near railway cross.

Young lady tried to check for train and actuated red light and wig wag manually! It was funny!

 

I removed the horns off my 359 and routed the air line from pull cord to a brake relay valve to run my K-3L Nathan airchime. I added an extra air tank and ran dual 1/2 airlines from the tank to relay and relay to horns.

I wanted a clean and hidden look when I opened the door.. Not a big fan of the huge chrome trainhorn valve there by the seat..

 

when I worked in big trucking company I had long stick with hook to pull air horn when driver sleeps in truck with open window in workshop)) just for fun!

 

Pablo, that reminds me of a trick a few guys used to do at a former job. Slip seating creates all kinds of opportunities for pranks.

1. Tie a piece of fishing line to the horn pull
2. Shut it in the window of the driver's door
3. Exit cab from passenger side
4. Lurk around with video camera to capture the reaction

This one got me more than once...

 

That's not entirely correct. I got put up in a brand new mack (154 miles) while my truck was getting worked on. Did the pre trip and saw the SOB had no air horn.

Well, I went and asked the shop foreman and he said it's not required. He further said the truck just got its first inspection the week prior, and air horn is not on the dot regulated inspection form.

I asked, who's the idiot that bought an oversized pick up then? I mean what if a kid gives me the signal? Am I supposed to say sorry, I have half a truck with no air horn.

Per 393.81 subpart G
The word "air" is never used when it defines the horn required for a cmv to be legal.


Ps always read all posts after because you'll see everyone already corrected the misinformed.

 

really horn lowndness and tone are regulated with ECE and DOT.

So u cant use any horn!

My favorite horn tone is Mercedes Actros MP2 horn)

 

Can anyone tell me anything about the Moss MFG air horns, they were out of Lima, OH I believe they are closed down but I have been looking for any info on them and can't seem to find any. I have a pair of their horns on my 84 International 9670 Doing some research, I got an idea what to do to make them work again. I removed the screws from the back and took the back off. Took out the baffle and cleaned them all up the best I could. Going to clean them up some more today and put them back on, and hope for the best. The springs are rusted but still solid and the baffles only had a little corrosion on them so they should be ok.
