If anyone is in need of fresh desiccant for their air suspension compressor, I have quite a bit left over. I had to buy several pounds of it to meet the minimum order, and after replacing mine I can say it seems to be exactly what was put in at the factory. I figured let me share it with other Jag owners so they don't have to buy 8 lbs of it to replace 1/2 cup!

However I did not find any of the larger size beads in my unit. See the photos below (old is brown, new is beige). I just dumped out the old and poured in the new 8x12 desiccant beads. I do have a quantity of the larger 4x8 beads if anyone has a use for that. My opinion is that the variation in bead size is just due to manufacturing of the desiccant, and it's likely Wabco used whatever they could get cheapest.
PM me if interested. I'm not looking to run a business with this, just as long as I come out even.
Do a real service to many and ziplock just the amount that one would need for the rebuild and let us know the price. We could easily mail you a check (or send via paypal if you have an account). When you receive payment you can mail it out in a simple first class package. You should break even nicely. I too would not want many lbs left over. Thanks for thinking of others.

That was my intention--I'm not looking to unload 8 lbs of beads on someone! lol
I'm going to divide it up based on what came out of my dryer, plus 25% leeway. Thinking around $10 should cover the material, shipping, etc. I have enough to rebuild 10-15 dryers, so anyone interested should let me know.

Sorry if that was not clear in my original post!
Sent pm. When should it be changed? I understood that the desiccant is dried at the end of a drive. I guess it gets somewhat dirty.

The 4A Molecular Sieve type desiccant can be reactivated by baking at 400F while under vacuum or passivated with another type of gas. What the 3 seconds of "reverse flow" that our suspension does on shutdown is probably of little value...
I think they really only expected these pumps to go 50k miles and then be replaced with a new unit. I'd say whenever you do the compressor piston ring the desiccant should be changed. That would be equivalent to having a new pump.

I sent a PM as well. Glad to contribute to get some of your $ back. Thanks for keeping your fellow X350 Jag members in mind..

Thank you! I'm glad to help out other Jag owners. Nothing I hate more than paying the dealer an outrageous price for a new part when all something needs is an o-ring or some fresh desiccant.
I've sold about half of the desiccant now, so have 5 bags left if anyone else needs some. If there's really a great deal of interest in getting more, we could figure out a group buy on another batch.

Big thanks to Michael for sharing - saved me from buying 8lbs of it . Now have to wait until the warmer weather returns to replace .
Fantastic gesture for a most reasonable arrangement. Wonderful to experience the spirit of this forum where business can be conducted sight unseen to satisfaction of all. I, for one, look forward to future GTGs where one can place a mug to username.
pkoko, used in rebuild of compressor for CATS suspension, bagpipingandy Jaguar XJ6 XJ8 XJR X350 Air Suspension Compressor Pump Seal Repair Kit #161120429299 is also of big time use.
Can someone explain to a total noob what is the desiccant for? I know that it absorbs moisture. But why?
The suspension compressor has a dryer (basically a can filled with the desiccant) attached which removes moisture from the compressed air. Any time you compress air you end up with condensation, and you don't want this being blown inside your air springs, hoses, or the valve block. Depending on the climate it could actually result in a significant amount of water in the system in a surprisingly short time. Aside from the obvious corrosion to the valve block internals, this moisture easily freezes and will stop the system from working or damage components.
