“Any hard-workin’ trucker who says he wouldn’t enjoy a ‘Loud and Proud’ train horn on his rig, prolly ain’t being 100% truthful!” Bryan Martin/Owner, 4 State Trucks
STEP 1: After tapping into your truck’s air supply, you will need to run your supply air through your cab floor into your valve and then back down through the floor. The pedestal simply mounts to the floor with 4 bolts. The air line coming out of your valve will go directly to the train horn.
Regardless of whether you’re running a 1-bell or 5-bell train horn, you will need to run a minimum of 1/2” air line to supply these horns.
STEP 2: To ensure you will not have any air leaks around the fittings, we recommend using pipe thread sealant to completely seal each fitting. Simply brush on the sealant to each fitting before securing.
Hook up your air lines and make sure they are tight because it’s pretty hard to check for leaks when the horns are blaring!
STEP 3: After you have everything hooked up in the cab, you can lower the fittings into the tube.
Notice that there are more threads showing on one side. This is because you will tighten the “air in” side first, then run the “air out” side in until it lines up with the tubes on your pedestal.
STEP 4: Before running the 1/2” air line from the valve and air tank to where the train horn will be mounted, insert the air line into a split loom to protect the line under the frame of the truck.
STEP 5: When it comes to mounting the horns, we usually build brackets to aid in mounting. This bracket was built in our FAB shop, however a couple pieces of angle iron, a drill, and possibly a little welding will accomplish the same thing. Tape off your bracket to measure for the holes that need to be drilled. Here, we measured 2” center to center.
The authentic red train horns we sell all have the same pad, so the holes are all drilled the same.
STEP 6: Once your bracket has 4 holes drilled, it’s time to get under the truck to finish up this job! Choose a location for your new horns – these are very heavy and need to be mounted to something substantial.
The inside of a frame rail works best.
STEP 7: Once your bracket is secured to the frame rail, it’s time to mount your new train horn to the bracket.
STEP 8: Start your truck up and let it build some air. Plug your ears and open the valve!
NOTE: The valve, air line, bracket, fittings, etc. are NOT included with the horn.
