Air Suspension (1 Viewer)

[Fishdude]

Hi.
Ive just purchased an Autocruise Starfire.
On the drivers step is a gauge with 2 pipes going to it. This appears to read zero.

I assume this is something to do with air suspension.

Can anyone yell me what to do with it.

Thanks

Fish

Hi @Fishdude and welcome to Fun.
I think those gauges are indeed for air assist and should not read Zero.
As I understand it, that me and the air bags are flat and will wear out quickly. I think there should be at least 2 bar in there but I'm sure you will get more experienced advice shortly.

Minimum pressure should be about .3 of a Barr (5 psi). I usually run at 25 to 30 psi (2 Barr ish).

Do not drive without any air in system, i park mine up and leave about 10 psi in and run at 40 to 50 psi depending on load.

Has if got valves on the pipes,,to select which side to inflate, if so both valves maybe shut and hence gauge showing zero.
Ps I could be wrong

It could also be that the previous owner removed the air bags when he sold it, or if he wasn't happy with them, but left the gauges so as not to leave holes on the inside

I had mine taken off when upgraded to fully automatic system, if the same as mine they are about 6" high and similar across, round rubber things, sorry not very technical but they should be visible if fitted on yours by looking underneath inside rear wheels

If they are fitted, then as advised they should have air in or will be damaged, having said that, when we bought ours we didn't know it had air suspension and drove 100's miles before we found out it had and worse had no air in one side at all, no damage done

Ours has a gauge and a tyre valve behind each front seat, I run ours @2bar to make it run level.

Sounds very much like "air ride" suspension...
As said should not be empty as that will ruin the air bags..
Turn taps so they are in straight vertical line with pipes (open), connect foot pump and give them a blow up..
Pressure should hold if everything is ok..

Wow, thanks for the prompt replies.
looked closer and it does say air ride on it.
It does register when I pump up with a bike pump, but the adaptor is naff.. Now need to get a decent valve adaptor.
Everyone agree at 2 bar?

Play with the pressure to see what suits, try a few trips and see how the ride feels...
Mine I run at 3 bar but it's more to get my "ass" off the floor and it does catch sometimes due to the long overhang..

Have a look underneath at the rear axle and you should see what looks like rubber bellows on each side, these are the airbags. The airbag can be seen behind the shock absorber,

My system is from VB and the gauges and pipework look like this,



Depending on the system you have fitted there are maximum pressures, the VB system is 3 bar max but after playing around with different pressures I now run mine at 1 - 1.5 Bar

 

[TerryL]

I tend to run mine at 50 psi - gives a nice stable ride without being too hard.

Thanks guys. Now at 2 bar, will see how that goes.

I'd been running our Dunlop system at 1.5bar but on the advice of the installer I upped it to 3bar. What a difference! Not only is the ride smoother and quieter but when overtaking HGV's and car transporters the wind induced "nudge" is absolutely minimal.
