Cls 55 airmatic pump fixed

[Andrew W]

Just fitted the new piston ring & O ring to my pump , 30 mins job done .
She now lifts instantly and the pump is quieter too. I used the kit from BagpipeAndy (eBay) £25
I didn't even remove the pump ,just remove the
2 bolts holding the cylinder head on and drop it down ,replace piston ring and use the 2 new bolts provided , stand back and chuckle how
you have just saved another £400 .

If anyone wants to know the exact tools needed
Or any more info just ask .

Will you have it re-calibrated on star to make sure it's aligning properly, last thing you want is miss aligned suspension at 90 mph.

Well I didn't lose any air and all the gaps around the wheel archers are the same as they were .
I'll stick to 70mph to be safe

I hear you

400? That's 200 too much lol.

Not at MB it isn't !!

But you would be silly to buy from Mercedes when you can buy the same part for 200 less elsewhere lol, also when I checked merc wanted 290 for the pump about 6 months back....

Why is there always someone who wants to dissect a post that's trying to be helpful .
I'm talking about a fitted price that most people
would end up paying , if you have a vagina and
just trying to be argumentative I forgive you

 

[Andrew W]

Lol

 

[JDMUK]

LOL!!


Wasn't trying to be difficult, doing what you did is probably harder than fitting the actual pump lol! So your £400 is well out lol


But fair play to you for fitting it lol, I have 2 broken pumps in the garage I'm going to order some rebuild kits and fix them and sell them lol

Your probably right.i should have taken a day off work , dropped the car off at a garage paid £250
For the pump plus £100 labour+vat , then go back to pick the car up then step back and chuckle at the fact I could have done it for £25
And half hours work LOL

 

[JDMUK]

Or like I said paid the 250 for the pump, fitting it is easier than the job you did and as you did that you could have done it prob taken less time than the rebuild took too

Nicely played Andrew, got to be happy with that! Yes as mentioned you can pick them up for around the £200 mark now, but why would you when you have fixed it in half an hour for £25. Result

£177 sound too cheap for a genuine wabco part?!?

Hi,
After reading this thread a week or so ago it prompted me to do some googling and after finding reference to there being an Airmatic filter. Googling this filter led me to a post on an American forum documenting the pump refurbishment, filter replacement and drying out of the dehumidifier granules.
I have now bought a new filter and a pump refurb kit, which should arrive at some point next week.
Primarily I am taking the pump off to inspect/dry the catalyst but while it is off I will fit the pump refurb kit and fit a new filter.
This work is intended to be totally a preventative maintenance measure, as I have no issues with the Airmatic system. Though I will say the suspension I always thought was a bit slow, but it currently passes all the STAR tests.
I think for just less than £30 and reasonably easy to do it is a worth while procedure to do.
I will put up a HOW TO/document the job, if others think it worthwhile.

You can also get a new cylinder head off Andy (eBay) for £45 if you want a total refurb !

I have not seen them, do they come with dehumidifier canister attached to them?
