York Air Compressor build

[TJVigilante]

While all that was happening, I bought and assembled parts for the system itself...coalescing air filter(oil/water separator), pressure gauge, check valve, pressure release valve, pressure switch, quick disconnect and a manifold to compile them all, as well as a 1/2" npt air filter and coil-memory hose and air chuck.



I also purchased a Kilby mounting bracket that removes the TJ serpentine auto-tensioner and relocates the alternator lower, to make room for the compressor, as well as a serpentine belt pulley, also from Kilby. These parts set me back a pretty penny...you can get the pulley through a truck supply store for half the price as through Kilby...I strongly suggest going this route. Kenworth part numbers are KA1480 for a 5-7/8", 6 groove pulley and KA1485 for a 5-7/8" 8 groove pulley.




Unfortunately Kilby has the monopoly on quality mounting brackets, and he knows it, thus charges through the nose for them. But I digress.

I'm using 1/2" npt fittings and hose from the compressor, routed around the engine bay to the filter ziptied to the core support bar on the driver's side...this is to allow the air time to cool from the compression before hitting the filter which is only rated at 150 degrees...the air can get much hotter than that. I'm going to use regular hose at first...hope that it doesn't start to blow off of the compressor fitting due to getting too hot. After the filter, I'll be running 3/8" npt fittings and hose, routed back over to the passenger's side of the engine bay where the air manifold will sit mounted to the inner fender.

I will use an existing switch and a Napa-bought 5-post relay to control the compressor, routed through a pressure switch that turns on at 90psi and off at 150. I will set the pressure relief valve at 155 psi to be safe. After installing my bodylift I will mount a 3-gallon air tank that I got for free (Thanks George!), and maybe a second one I am looking to buy from FlatblackXJ under the tub next to the rear driveshaft. This tank has a 1/2" npt outlet I can route to a quick disconnect somewhere in the rear of the Jeep to run air tools and use as a high-volume source of air for reseating tire beads. Originally green, I sanded it down and painted it with Rustoleum Hammered style black paint after cutting off two large, unnecessary mounting brackets with a dremel.



I will post in-progress pictures of the install as soon as I start to work on it.
