Compressor kit well worth it.

[Homestar]

As some of you know, I've sold the L322. :(. Time to let another family enjoy it as we simply don't use it enough to justify having it around any more. SWMBO has a small Jap car to commute with and I have a company car, so the poor thing just sits there waiting to be loved and driven again.

So, with that comes a bit of overdue maintenance on it for the new owner which I said I would do, and really needed doing anyway. One of these items was the noisy compressor. The current compressor was nearly new when I bought the vehicle - it was made in 2009 and is a genuine LR part - the PO replaced the whole thing - presumably at great expense.

Well, after years of SWMBO dropping the vehicle to access height every time she drove it the compressor had become noisy and slow to build air after cycling the suspension. Using the IID tool to monitor the pressure in the system, when it cut in at about 140PSI it would take about 4 minutes of rattling away until it cut out at around 185PSI. It had got pretty noisy - enough to be heard clearly over the engine running, conversations etc.

So, I dropped a few dollars on one of these - http://bagpipingandy.com

It took over 2 weeks to turn up, which is a fair while compared to what I usually buy from Old Blighty but it got here last night and I put the new piston ring on. Installed it today - the sound of silence is blissful. :D. Builds air almost twice as quickly now and you have to stick your ear to the floor in the rear to hear it run.

Some pics below - it's a simple job and he has a great video on YouTube with a blow by blow description of doing the whole job if you're not sure. I would rate this a 1 out of 5 for difficulty - anyone with basic tools could do this.

All apart - about 10 minutes work after the 5 to remove it from the car,

New and old rings.

Wear on old ring - it was quite hard compared to the new supple unit that arrived too, so not hard to work out why it was noisy. Also, the piston has no gudgen pin, so rocks side to side making a good ring that seals well even more critical.

The rest of the compressor is in great condition, the motor still spins very easily and I would imagine many compressors have gone to God that probably only needed this doing to them.

So, if you have an early L322 with Wabco compressor that's noisy and seen better days, drop a few quid on this kit, I think you'll be very pleased you did. :)

Thanks for that. I have never even heard mine but after 25 years in helicopters I am not surprised. I do lower it all the time for the kids though so I will file this away. Cheers.

You'll know if/when it happens as it sounds a bit like a small helicopter is trapped in the boot. :D

The kit only fits 2002-2005 L322 compressors, not D3.

[Homestar]

Yeah, not sure what else it may fit but there's a lot of different models that used this style Wabco unit. The EBay store has a full listing of makes and models it fits.

Edit - looks like in the Land Rover stable, it fits D2 and early L322, not D3. Also fits BMW, Audi, Jag, etc, etc...

I just found this thread when I was looking for a place to put my post. Gav, can you update your initial post with images? If needs be, I can add them back in for you.

I was away for the past two weeks on holiday and had the dreaded air suspension inactive message come up. I cleared it with the GAP IID tool but it would recur. The error message was about not detecting a pressure change (I didn't note it exactly).

Luckily, unlike the P38A, the L322 doesn't drop to the bump stops when that happens so I was able to get the final 300+km home without issue.

So I hunted out, amongst my spares, the bagpipingandy www.bagpipingandy.co.uk repair kit for the Wabco compressor I bought back in July 2016 just in case I needed it (can you see the P38A ownership coming out in me?)

Replacing the piston ring was relatively easy. The cylinder bore didn't appear or feel worn but the old piston ring did look a bit sad. (I'll take a photo later.)

Here are a couple of pics which complement Andy's instructions (click on image to enalrge):

Unclipping the wiring connector from the bodywork. Andy doesn't say how to do this but through a bit of experimenting I found one twisted the connector 45 degrees and it popped free of the mounting bracket. (Hmm, my fingernails look a bit grubby.)

Removing the plastic cable clamp - the instructions don't say how to do this. It just required slipping a screwdriver behind the two mounts and levering it off. The clamp is pushed onto two threaded studs.

Removing the temp sensor
If this bit is unclear, the temp sensor is retained by a clamp bolt accessible from the back of the frame.

The old piston ring before removal. I'll add another pic (after removal) later.

The car lifts much faster now, I'll see how it goes over the next few weeks.

G`day ,

just shy of 300k and compressor is still going and so is the GM auto , recently the radio stopped working and the wiper washers don`t pump , still under 10 to 100 though diesel has doubled or better since we got it .
