Hey Anthony, just been through the SLS woes myself. Not sure if anyone has suggested, but once you have air in the bags (by however means you can) Spray them down with soapy water. I found my leak in seconds that way. If your bags are over 5 years old they are prob due to be replaced anyway - the rubber becomes porous as they age.

If it's bags - you'll save a lot buying your bags from the UK if your able to wait an extra week or so. I bought mine locally *cries*.

If your comp is running, get busy with the spray bottle of soapy water and check all your lines and connections for leaks too.

I now carry a bush repair kit like what Pedro suggested (air line, shrader valves, push in connectors etc -$50 total) and with my 12v compressor I can have the Canyonero back on the road even if I tear out the comp and all the air lines somehow :-)

Where do you get such components? Does a 4mm SMC push-in connector thread into the rear of a schrader?
TIA
Steve

I had a hard time getting them from the usual places you'd expect in Bris. Ended up finding a great mob at Brendale called Fittings Express - 07 3881 0883. They have a website: We Carry Pneumatic Parts, Pneumatic Machinery, and Airline Installations for All Your Pneumatic Requirements and can prob send anywhere in aus as they are very small bits.

The items I bought were (to make a pair for both left and right bags):

• 2 x 1/8" tank valve
• 2 x Male Stud Sraight 4mm x 1/8"
• 2 x Socket Hex 1/8"
• some 4mm air line

I've attached a pic of what my emergency get-me-outta-da-poo™ device looks like. I'm thinking of selling these pre-packaged. Also working on a quick fix to reinflate a leaking bag sufficient to get home on.

Of note.. the valve weighs a bit, so a cable tie to keep it from flopping about is a good idea imho. :-)

Attachment 26172

Cheers.

Sorry Steve, I didn't actually answer that properly. No! Mine didn't, the 4mm x 1/8" stud is the push in connector, then that screwed into the 1/8" socket, then the tank valve is the shrader which screwed into the other side. :-)

Looks good Wil

Does the bare end of the line connect directly to the leaking bag or do you permanently set it up at the compressor?

In the case of the one pictured in my previous post, that bare end plugs directly to my Dunlop airbag (as it has a push in valve). If you have the threaded connections on the airbags you would need an airline that finishes in that connector. I've got a salvaged one from an old air line that I have on another piece of line. It just plugs into the schrader valve instead of the blank airline. That gives me the ability to connect to both types of airbag connection.

A note about the threaded airbag connections. The little metal olive (collar thing) around the airline that creates the seal when threaded, is REALLY easy to break!! I broke 2 removing them from old air lines in order to recycle the connector! I'm sure these are available to buy as a part, but haven't looked into it yet. Hooray for push in connections!!

Cheers

PS. These schrader valve solutions will help you out if you lose your compressor, or rupture and air line, but if your bag is leaking, it will continue to do so. With the schrader valve added though, it may be possible to use a can of that green tyre sealant goo in order to get home on a leaking bag. This is untested though.... a few people have discussed it here. If anyone has any leaking airbags that are bound for the bin - I'd gladly take a couple of dead ones as donations to test that theory out.

Wil - Happy to post you an original LR Contitech airbag I just removed (2003, 160K km). It has an intermittent slow leak. (The other one I'll keep as a spare as it doesn't leak) PM me your postal address.

Tested & proven to work.

Cheap, easy, temporary repair that should get you out of trouble.

Hi All,
Whilst on the airbag suject, but not broken...yet.
I have just purchased a 2004 SE with SLS and my son has inherited my 2002 with coils. I am sure this has been asked many times before, but what is the advantage of the SLS over coils. I have found the SLS to be more twitchy on the road?

are the tyres different widths between the 2? is one lifted the other not?
air bags wouldnt make it ''twitchy'' as such, ACE can give this feel though.
dead shocks wont help either.
mine was twitchy with a 3'' lift and 255 55 R18's, now with 255 70 R16's its completely different.

cheers phil
