One of my rear driver’s side bags is leaking a little around the piston, causing the back end to drop after maybe 30-40 minutes. I’m thinking that the other side’s leveling valve just compensates, letting out air to level until it’s all down. I wouldn’t care so much if the whole coach dropped, but the front stays up for days now that I replaced the two pax side front bags, so the coach sits a little “uphill” not long after she shuts down. Anyhoo, I remember reading somewhere about using tire sealer goo for slow leaks in bags, so I bought some. Trouble is, how do I get it in the bag? Ideally, I would like to disconnect the line just aft of the leveling valve and squirt it into the line… but I can’t visualize getting 8 oz. of the stuff to go into the bag that way. The bag doesn't leak enough at low-pressure to pump the stuff into it that way. If I go to the trouble of removing the top of the bag and deflating it down to fill it with goo… I should probably just replace the thing. Any thoughts or McGyver-like goo-ing contraption ideas? Something like an oiler on an air compressor... Brian Brown PD4106-1175 Longmont, CO | ||

The only thought that comes to my feeble mind.... is..... When the bag deflates via the leveling valve, that goo will be passed thru and may goo up the valve and whatever else you may not have had the intention of gooing... On a standard RV type air bag, the air is intended to stay in, so the goo wouldn't present any problem... It just doesn't sound like a goo idea to me. | ||

Not to mention that some of that stuff will eat both the rubber and the metal if it's left in. It's made to get you off the side of the road and blow the head off your tire guy when he's trying to fix it. | ||

HAR... Hey Nick.... That new green goo isn't flammable.. Yer thinkin' of that old "flat-fix' crap. The new stuff will make the inside of everything look like gator puke. It's sticky, green snot kinda' stuff. The tire guy will get Peeeeed, but will be otherwise intact. | ||

Good points, JTNG. I never thought about the goo heading back upstream, but you're absolutely right. I guess I'll have to replace the bag after all. Sigh. "It just doesn't sound like a goo idea to me." I got a good, I mean goo laugh out of that one! Thanks, Brian | ||

Does your coach have "air beams"? Or blocking plates (aluminum) that were added later? Pinhole leaks in air beams or blocking plates can make you crazy.... Look for corrosion or rust on the framework above the airbags. Many times the bags themselves are not leaking but what they attach to can leak. Get your handy spray bottle, add dishwashing soap and spray everything with the air up. Look for those insidious bubbles. | ||

David - Brian has a 4106, which uses rolling lobe air bellows without air beams. The soapy water is the air suspension busnut's good friend. Even more fun if you use kid's "bubble" stuff. Make it yourself w/ Dawn dishwashing liquid, water & glycerin.  | ||

Bite the bullet and buy some new bellows. Yours will never get any better. They just might let you "down" in the middle of nowhere on a dark and stormy night. Jim | ||

good advice Jim, to go through that work to try and band aid an air bag just is not worth doing as you will have to fix it properly later and it may be sooner than you think.spend the time doing it right the first and last time hopefully and it is done.the time that you spend trying to give it the quick fix plus the time and anger that will be spent cleaning up the mess will be greater than the time to do it right the first time. | ||

Caution to save you allot of trouble; DO NOT USE Goo or Liquid SEALANT in air bag or lines. It only made for tubeless tire. Do what others common sense posts said….leak checks …..repair or replace worn-ed with new parts. About air bag are like tires…..they aged & leaks so need replacement is normal.

This may not help anyone, but... I had a leak that was so small in the airbag system supporting my generator. I used the flat tire sealer and it has been "hunkie dory" ever since. | ||

Lew- That green goo stuff is great. After the hurricanes down here in Florida, there were roofing nails and sheet metal screws all over the place. Everyone I knew were using that stuff in all their tires. It was the only way to keep rolling. I'd pick the screws out when I was in the mood.... Your genset air bag is a lot like a tire. It doesn't have leveling valves to get gummed up. It's like the air bags in an RV... No leveling valves; just a fill valve. The bus air bag system is more complicated.... that stuff could play hell in a big $$$ way. | ||

Lew I believe that stuff Is great when you have no other option and for a temporary fix It Is ok,keep In mind that It Is just temporary. | ||

T I realize that it is just a temporary fix, but I was filling the airbags up almost monthly and now I do it about twice a year. That is good enough for me. Even then, I am only down a few lbs. and that's great. |
