Where is the check valve located on the rear airbags?

[Mr. D]

Hey guys anyone know where to find the check valve for the rear airbags on an ' 88 345? My line appears to wrapped much of the way to the axles and I'd hate take it apart if it's not necessary. Thanks

It's near the bags.

It's also a very small brass part.

Thanks Andy, just in case I might need one, do you have these in stock?

Yes, we have it in stock.

Best way to tell if one is needed?

If the air in the bags bleeds down when parked, either a bag has a leak or, the check valve is stuck and is allowing the air to bleed down, through the compressor.

The check valve on my 310 (when I owned it) was very hard to find and caused no end of problems for the PO and me. I honestly think that is why the unit came up for sale. In the end, after I located it, it was not allowing any air at all to go in either direction through it. Once I replaced it all was fine and I never had another bit of problem with the air bag system.

I got under the rig again yesterday and as most of you who own these 345's know there ain't much room under those airbags and axles. I can feel my air lines come into the bags and see where they connect to the air tank but by feel only it seems that there may be some nuts or fittings on the top side of the right rear airbag (looking forward) that don't seem to be on the left rear airbag. Is that where the check valve would be on an '88 345? or have I over looked something? As usual Michigan has dropped about 20 to 30 degrees in temperature and today is freezing so I will resume my search for the airbag check valve when weather permits. Any suggestions would be welcomed. On another note does anyone know what the psi for the bags should be?
