Well that blows! And that's a good thing! 4x4TruckLED had a pretty good sale, I guess for fathers day. I bought the ARB twin compressor kit along with the KR Off-road engine bay bracket, air pump kit and the ARB Digital Tire Inflator. This was an "easy" install. Estimated to take an hour to hour and half, only took me a little over six hours!
The first step was to loosen up one of the nuts on top of the shock mount. Slip the foot under the nut and re-torque to 41 ft-pds. Repeat in 100 miles. Easy.
You mount the compressor to the bracket, went ahead and set the output to a 45 degree angle. I believe this is suggested to ensure it clears the inside of the hood.
Next, came the dang fiddling flipping bracket of despair. So you remove 3 Ford bolts from the fender. 1, holds a ground wire. 2, and 3, hold a bracket that has a module for something mounted on it. Oh, much fiddling to get 2 and 3 installed. In fact, I clumsily dropped 2 into the bowels of the engine compartment. I didn't feel like taking the skid plates off to look for a bolt. So a trip to Tractor supply to get a 6mm- 1.0 bolt. The original has a built in washer, I subbed with a washer I had. Fun note: I ordered a Ford bolt for a little over $5 including shipping. What fun! Finally, got both bolts started and then I realized I wanted to mount the switch to 2. So more fiddling around. I happened to have some aluminum bar stock shaped like a "Z" that came with my Bro Flap mudflaps and didn't need. Drilled one hole in the bar as it already had a hole that would work for the second bolt. Finally all the hardware was installed.
It is pretty easy to run the compressor cable to the battery and hook that up. Then there is the switch. One way is to hook it up to the Aux switch. Well, all my Aux switches are currently in use. So I was going to use one of those fuse taps, pushing it into the battery fuse location. Your mileage may very but I couldn't get it to work. So I just connected the power fire that goes to the switch to the battery. I did have the wisdom to insert a fuse link in between. Safety First!
It was now time to test! Powered on and the automatic pressure switch shut off the compressors as expected. With all the line connected, I added air to all the tires and really didn't take long at all. To be honest, they only needed a couple of pounds. Then I turned off the air compressor and the Bronco. I discounted the hose at the compressor. That was a big no no. SAFETY FIRST!!! I had failed to bleed off the pressure in the line. So when I disconnected the hose and metal fitting went sailing through the air and hit my workbench. It had just missed hitting the rear window of my hard top which hangs overhead.
I learned my lesson, I aired up the tires again today and this TIME, I bled off the line air pressure before disconnecting the line. Perhaps old dogs can learn new tricks. All my other air compressors did not maintain line pressure, so this was a new experience for me. LOL
