D3/RRS Air Compressor

**101RRS** · 9th March 2012, 12:48 PM

After jacking my car on the air compressor I am now in the process of putting in a new mounting bracket. However the top and bottom mountings on the actual air compressor are also bent and I need to straighten them out. To do this I will have to disconnect the air compressor from the wiring harness and the three pipes.

I have the workshop manual and it just says remove the three air pipes but does say how to actually do it.

The front pipe is no issue as I just undid the brass union but the rear two I am not sure about. The look as if they just prise out (the metal bits) of the air compressor but I do not want to do this in case it is wrong and I damage something.

So advice on how to remove the rear two pipes would be appreciated.

Also there is a large pipe (about 1.5cm across) that ends at the top of the air compressor but is not connected to it - seems to come from the rear of the car - any ideas what it is?

Thanks

Garry

The above question is not longer relevant as the plastic pipes got damaged

so I cut them off

- off course when the air compressor was completely free of the car the two pieces of pipe came off no issues

.

So I have bought some more pipe and some brass connectors so that in the future all that will be needed is to unscrew the connectors rather than try and get the pipes out of the air compressor.

Now to put it all back together.

They are quick connect fittings and you need to push the collar in and pull. Sometimes it needs cleaning and WD40.

There is nothing quick with those connections. They were a real pain to do and I could not do them when the compressor was in place and connected to the pipes - I cut them and have now replaced them with a brass join.

Putting the lot back in now.

Exact: this is the right way!
Push the air tube to the compressor, keep the "edge" metallic (or plastic) button, then pull on the tube ...
Do not forget to disconnect the negative battery cable before any intervention or disconnecting a "connector"!

picture may be helping to understand ..
You can see the"keep the "edge" metallic (or plastic)"on the top ...

(sorry for my bad English)

Problem was that I already knew about the potential problem - just rushing as I was with a group and shoved the jack under the car in a hole that looked right - crack crack crack before I realised - too late.

The air compressor has been held in place with a rachet strap for the last 2 months and is working find - just a bit noisy as there is no insulation and is hard against the chassis.

Whoever designed that mount and the way it bolts up needs to be sent to a hell of having to remove and reinstall that bracket. Blind Freddy could design a better system - the top bolt will not go in as the top insulation cover is in the way.

Oh well I have all day tomorrow to try to get it in - even though it should be a 15 minute job.

Hi again...

More help here (with pics) : DISCO3.CO.UK - View topic - How To - Air Suspension Compressor replacement

hope is can help you !

Thanks - have those but the pipe clips did not work as advertised - it was only when the pipes were cut (noting the D3 site tutorial had to do the same thing) and the sir compressor removed that I was able to lever the pipes out. Even with the collars pushed in there was no release.

As I said before the whole design of the mounting system is crap and not worthy of the vehicle - whether it be D3 or RRS.
