Thread: LR3 suspension compressor air fittings

When I removed my compressor a couple of years back I had the same issue and had to cut the pipes a couple of inches from the compressor. As you indicated these pipes are the air intake from the air filter up in the drivers side rear quarter and the compressor exhaust pipe which goes to the same location. Both are low pressure so dont need any special piping.

I just used some rubber fuel line of the appropriate size as a joiner to connect the short bit of pipe coming out of the compressor to the pipes already running under the car - works fine.

When I did mine, I used my shop compressor and the blower gun with a thin nozzle to blow out all around the compressor. Dirt gets jammed in the push fittings meaning that you can't press them in to release the collet and so the tube.

After blowing all the dirt out and gentle prising with a fine flat tipped trim removal tool, they undid fine. Re connecting cut lines, any for of vac tube g or rubber hose of the right ID will do.

Or source a couple of quick connect air fittings

Hi guys

Thanks for the feedback. I managed to get it all back together and connected - just got sone 6 & 4mm steel pipe and pushed it into the hoses - had enough slack so just pushed them back into the snap fits. Will do for now until I can get some free time to replace the connectors.

However....system wont repressurize. I stupidly drained the air tank before I refitted the comp and now even tho the compressor runs about 5 mins it isn't pumping anything up...anyone got any ideas?

Thanks

A couple of things to look at :

• The compressor is stuffed
• There is a leak in the gallery (that could be between any valve block and the compressor)
• The pressure sensor is stuffed
• The exhaust valve is jammed open
• There is a leak in the dryer

Thanks Brad

Given that all was reasonably well (albeit with a small leak somewhere) pre compressor redress, I'm going to check the exhaust valve first....that's the only thing I really messed with whilst removing the compressor...

Plus the air lines that you cut.....

Thanks all
Traced the issue to a jammed open Exhaust valve (as advised - ta) - so compressor now pumping.
I am getting air into the reservoir block now, but v slowly - compressor runs for 12 seconds then shuts off - and it isnt hot. If i switch the car off and restart, comp fires up again for 12s...going to take a long time to pump up at this rate - does this sopund right? I was expecting the pump to run longer and shut off if overheating...
