Installing Outlets for Airing Tires

[Glennman]

I'm planning on installing connectors for airing tires. At the rear of the bus, there is an air chuck inlet at the bottom of the air dryer, and at the front there is an air chuck inlet at the small air tank under the driver's seat. Would those be good places to install air chucks for hose connections? I'd like to install one at the front and one at the rear for convenience. Any ideas on that?

That's a great idea as it is always a pain to drag a 50' hose around the bus from my compressor that is in the engine bay. keep us posted.

There should be a air connection on the passengers side rear door on the D's,you need to plumb close to compressor at the rear, my D had a connection at the auxiliary tank up front too but it had a 1 way check valve and was regulated and was useless except for a tow truck to connect.

The front one Glen is to release the air brakes like Clifford says for a tow truck. One in the rear I hook a hose to and leave it half way down in the bay ceiling with a tee and a hose going both ways with an NPT fitting on the ends. That way when I want to fill tires I just plug in a short 12 foot hose and can go to any tire to fill.

okj, I'm not clear. On factory MC8, is there an air outlet one can use to connect to for filling tires in the front? I know about the one in the rear passenger side and have used it to air up the bus.

Sounds like I need to stick with a long hose and one connection near the compressor. Too much regulating going on with the systems at the front. I'll take another look at it this weekend. Thanks everyone!

Don open tool bay under driver at front and look inside to the right just under the supply tank there should be a shradder valve there. Like a tire fill valve.  There might be a check valve though on that one because that is for a tow truck to hook to so they can release the air brakes to move it.
I put a tee in the rear off the fitting that is already there. Ran a line to the middle of the bay #1 and teed off to each side with an NPT fitting at the ends that I can hook to.

I always ran the same pressure in all eight tires so I had a preset regulator at the rear and used a clamp on air chuck and never worried about the pressure and didn't need to stand and keep checking the pressure on each tire

Great idea luvrbus! Thanks for that!

[luvrbus]

Great idea luvrbus! Thanks for that!

You can always add a gauge at the regulator if you are one that uses different setting on other axles, I set mine and forgot about it,checking tire pressure on a bus is time consuming

Good idea thanks. Ya I have to stop when doing it because it hurts my thumb, lol

[Jim Blackwood]

Great idea. I have a regulator I can put with the air hose and a clip-on air chuck.

You're putting in to much air? Lol

I don't run my engine here at the shop for airing my tires, I plug the rv into shop air but still use the same hookup on the RV just a different air supply to keep from burning fuel

Clifford's suggestion is great when one pressure is desired. From the recent discussion on tire pressure, it seems there are three different pressures required to properly inflate tires: steers, drives, and tag. Each carries a different weight so three different pressures.
