Air Compressor Install


Jeep
Viair 450C continuous duty air compressor with added outlet elbow.

Jeep
Inlet needed an elbow as well.

Jeep
Test fitting it onto the ABS tray.

Jeep
Bolted to repainted ABS tray.

Jeep
Ended up removing the compressor's head and cylinder to get it in position.
Note missing bolt in foreground left mount. See text.

Jeep
Cylinder back in position.

Jeep
Head reinstalled with outlet hose and elbow.

Jeep
Partially populated manifold with local pressure gauge.

Jeep
Overall view.

Jeep
Grey disk looking thing at the top is the compressor's intake filter - placed high up.

Jeep
Intake hose from filter fits on this barb fitting on the front of the compressor.

Getting this thing installed was a bitch. It fits as shown, but getting it in while bolted to the ABS tray was a challenge. There really wasn't any way to install the tray first, then bolt the compressor in, so it (the compressor) was partially disassembled as shown. The missing bolt shown above was installed after the rest of the job was complete - I had to drill a matching hole in the flange the ABS tray sits on top of, but forgot to take a picture of it at the time. Bolts and washers were provided by Viair, but I used nylok nuts in leu of the standard nuts and star washers provided. M5 sized hardware.

In hindsight, it may (or may not) be possible to install the compressor straight-on sideways instead of diagonally as I did it *IF* rotating the head 90° would allow doing so. The compressor head apparently can be installed in any orientation, something I didn't know when I started this project. *shrug*

Jeep
Bracket being fabricated...

Jeep
Several ¼" elbows used for compressed air. Drilled them out to 5/16;".

Jeep
90° bends are restrictive, so why not open it up a bit?

Jeep
I certainly don't need the 10K PSI rating of this part, it'll still be good for 150!

Jeep
Bracket installed with air connector and associated plumbing bits.

Jeep
If it weren't for a "BCH", nothing would fit on a Jeep!

Jeep
Pneumatic tubing installed...

Jeep
...and shaped with a heat gun. Hopefully it will stay that way!

Jeep
Viair supplied pressure switch. Everything else in the system is plumbed
with ¼" fittings, yet this came with a ⅛" end. Needed a bushing to adapt.

Jeep
Viair supplied manifold. The pressure switch was so damn BIG, that I had to extend
it out a bit so that it would clear the elbow for the local pressure gauge next to it.


Jeep
Connecting the compressor and pressure switch to the pre-installed wiring.

Jeep
Wiring loomed up.

Jeep
Connections to pressure switch hidden under the cruise control servo.

Wiring is now connected and operational. The relays installed shortly after I purchased the Jeep, along with switches and control wiring done shortly thereafter now control the compressor. I had forgotten in the 2 year interval that the relay was wired as a low side control, so there was a bit of momentary confusion until I figured that out. The Compressor isn't too awfully loud from inside the cab until the engine is started. The increased voltage makes the compressor much louder and increases vibration. Hopefully, that will settle down when its pumping into the tank (its open right now).

Jeep
Figuring out the in-cab pressure and vacuum gauges. Note the LED installed
in the pressure gauge's bulb socket. Vacuum gauge is LED from the factory.

Jeep
Vacuum gauge was such a tight fit that I didn't need to use the bracket.
A tight squeeze to get all this stuff into the dual gauge housing.

Jeep
Wiring up the illumination.

Jeep
Done, except for the pressure line.

Jeep
Bolted onto A-pillar trim piece.

Jeep
Backside showing wiring, vacuum and pressure lines.

Jeep
All the wiring from the radio bar that was hidden behind the A-pillar escutcheon.

Jeep
Working the wiring, air, and pressure lines into the dash area.

Jeep
Outside view - escutcheon back on.

Jeep
Gauge housing as seen from the outside.

Jeep
Inside, lites off.

Jeep
Inside, lites on.

Jeep
Inside, lites on at nite.

Jeep
Ended up revising the vacuum line to the vacuum gauge with an ell.

Jeep
Vacuum gauge operational.

Gauges installed. Getting the "blackout" style vacuum gauge was a bad idea, forced me to wire both gauge lites to switched +12, which results in an obnoxiously bright lite, esp. from the Viair pressure gauge. The Viair lighting is strictly "Old Skool" - an oversized socket assembly for a tiny bulb which I replaced with an LED. The "LED from the factory" vacuum gauge is tolerable at nite, but both really need to be dimmer. I'll either add a resistor or a voltage regulator behind the dash to dim them down a bit. Speculating that about 8 volts would be good...

Jeep
Far easier to deal with the stiff air line (to the gauge) under the dash with an Ell assembly...

Jeep
...plus it will give me a quick disconnect if I need to pull the A-pillar assembly again.

Jeep
Gauge plumbed into the under hood air manifold (2nd from right).

Jeep
Current stack of parts. Tubing, tank, water separator, and heat exchanger for
finishing up the compressor project, plus H&R springs and Savvy cable shifter.

Jeep
Holding Air Tank in place temporarily...

Jeep
So I can mark the drill holes.

Jeep
Water separator

Jeep
Heat exchanger, hopefully most moisture will precipitate out...

Jeep
... and get trapped by the separator.

Jeep
Holes drilled and primed in the passenger side rear footwell.

Jeep
Tank bolted in.

Had to give the Jeep a lift to be able to get at everything.

This was a minor pain in the ass, I'm a big guy and there's just no room under the Jeep. Jacking it up as shown only helped slightly. I ended up having to get my wife to help, and I put temporary fasteners to hold the tank so I could get the jack that was holding the tank up out of the way. Then it was just a slow and tedious job to get everything in place and secured.

I'm hoping that the heat exchanger and water separator combination will reduce the amount of moisture going into the tank. The air will still be pretty hot from the compressor by the time it gets to the exchanger, hopefully it'll cool enough to precipitate at least some of the water - time will tell. Note the cord actuated drain valve.

Jeep
Air lines all run, the rear one went through the frame part way.

Jeep
In cab air gauge.

Jeep
Rear outlet.


Safety relief valve trips before the pressure switch turns off...


Jeep
The most important addition to date!

Jeep
Its always in Home Depot's parking lot when I see another Jeep.

Jeep
Guy on the Jeep forum makes these for $40/shipped...

Jeep
Very good quality - well made!

Read on for the next part!
