Journey Aux compressed air connection

rshackleford · 07-15-2012, 07:54 PM

I have an 01 Journey and in the storage area behind the first step there is an airhose. I strongly suspect there is an AUX compressed air connection somewhere, Im just not too sure where to start looking.

Did the Journey come with a AUX air connection from Winnebago? if so where can i find it?

It not, is there a standard location for adding an aftermarket one?

I would think there should be one. Mine is next to the generator under the front bonnet. Is there a gauge near the connection you have?

Not sure what chassis you have, i know freightliner used to put an auxilary air block on the fire wall front. for hooking up airhorns and such. i put an milton air quick connect on mine.

On my 05 39k the air source is in the generator compartment up front. Opening the access cover beneath the windshield, there is a quick connect fitting and a yellow valve handle on the upper right.

It may have been an option, but if the valve and connector are not there, I believe the manifold it all attaches to will be.

Yep, mine is on the front firewall on the right as you are looking in.

Mine is the same as described above - upper right corner after opening the "hood".

So is this it??
If so, is the smaller "Vale stem cap" for checking air pressure?
Can I remove the plug on the top left in the pic and replace with a quick disconnect?

Well that is certainly similar, but I do not think the same as on mine, but then again mine may just have a line that goes to the same one you show. Mine may have be located where it is for convenient access when it was set up for the air hose connection.

I suppose you could tap into that open port, but I would confirm that with Freightliner to be sure this is the proper portion of the two-part system.

Since you found the hose, though, I can't help think there must be a connection port and valve somewhere that is fairly accessible. Have you looked in the engine compartment? It is possible, I guess, that the PO carried a portable compressor and just forgot to take his hose.

Looks like you can just add a hose discconnect. the air Valve stem may be to add air to the system in case of engine failure so you can release emergency brakes that require air pressure to remain off.

I read somewhere that if you need a tow, you need a tow truck that can connect to your air system to release the brakes. I pictured a tow truck driver grabbing an air hose and plugging into a quick disconnect somewhere on my rig. I wasn't envisioning a standard valve stem to air the brakes up.

However, I have figured out my immediate question with everyone's help.
I took a closer look at the air hose and it has a bicycle tire pump type of connector on one end that connects to the valve stem and then has a lever that grabs the stem and also pushes down the core to allow air to tneter the tire.

Same setup only in reverse on the coach. The hose attaches to the valve stem on the Aux air connector and the other end has a standard air chuck for filling tires. I suspect it was used for bikes since the air hose is no where near long wnough to reach the tires on the coach.

Many folks don't bother with the coach AUX air for filling tires since it takes a little extra effort to keep the coach air compressor engaged and the pressure high enough.

While it does take up some storage space, I carry a Craftsman 150 PSI compressor.

I've attached a photo of the air outlet on my Journey. Looking into the front area it is above and to the right of the generator. The gauge displays the air pressure and the air hose fits into the fitting with the yellow valve handle. I use this for bringing up the tire pressure without problem.

I have the same basic set up as yours and am able to air up my tires easily with the onboard system. You might try using your fast idle to get the compressor to put out more air.
Because of the weight of my coach I use 100lbs Front and 95lbs Rear maybe that the differance.
Just a thought.

Wow. Your 04 Journey is much more finished off then my 01.

I need to get the extra parts to finish mine off like that. The guage and shutoff, as well as the quick disconnect are very nice.

Has anyone tried running air tools off the Aux air? Im wondering if the compresser has enough reserve to run air tools.

SVTotem · 07-17-2012, 05:33 PM

Chuck,
Originally I was carrying five pounds more front and rear, but now I carry the same as you. Have not tried onboard air since the change, so it might work better now.

It was necessary to hit the brakes to get the pressure low enough to kick in the compressor to again get the pressure higher than the tire.

I could always try it again.
