ET air valve

Recommended Posts

Weather was so nice here today I decided to take the truck for a drive plus fuel prices dropped some so put fuel in the truck. Anyway to my question, the air leveling valve on my hitch is leaking, I assume it just needs replaced but not sure what one to get or where, any info would be great. Thanks for any help.

It's a cab leveling valve used on Volvo trucks  P.N.  85104648, any Volvo parts department should have it, they are very tough, I would check the lines and fittings first, before you suspect the valve.

Thanks Henry, the air feels like it is coming from the rear of the valve what looks like a black diaphragm or disk like.

That's normal, there is a slit in the diaphragm and inside in front of it is the actual valve which releases the air if needed. Diaphragm prevents things getting into it (like mud dubbers). Your's is a JR, isn't it?

The hitch and the truck suspension should come up about the same time after starting the truck. The valve should not be releasing air once the truck suspension and the hitch stabilize. You should have about an inch of space between the top of the platform walls and the stop plates as shown.

 If it's different "we need to talk" how to make it" 1 inch.

The truck is in dire need of some new suspension bags this spring ( first on the list ) but the valve leaks badly when everything is aired up, the hitch works like it should but don't want to get caught in a bad situation from a bad valve. I might need to contact you after the bags are done to see that all is right, thank you Henry for your help.

Oh, I get serious about air leaks. Spend most of day chasing them. Then holds air for day or so. Few months later, leak down in half a day. Start all over. Seems a common thing

My old 1984 Pete 359 dual axle will hold air for a week. The suspension a couple months. It even has air windshield wipers and air for transmission . It also has rubber lines and flare fittings. No plastic and pushloc type fittings. Guess the don't makum like they used to. Kids bubbles and a squirt bottle usually will find a leak.

They still do, it's just an option.  $3K gets you a whole truck made out of FC350 hose.  You'll become best friends with your 9/16 and 13/16 wrenches...

Can't remember exactly, but I think nylon truck tube (J844) was invented in 1982?  Got its TMC color designations in 1984?

Let's have a new contest-who can guess where Scrap's shift pattern comes from?

COOL, but I bet Bennie couldn't remember it.....................

That has to be the worst tasting thing I’ve ever tried outside of lutefisk.
