SL55 AMG (R230) - Noisy bottom Pulley (Air Conditioning Compressor?)

The bit pointed at with the red arrow should be part of the outer bit that you have already removed

Wow as you say, no wonder it's making noise.

Your pulley has broken. The bit you removed should be unthreaded. And be removed as one piece. If it has (hard to see from pic) then your pulley will just fall off when you take the belt off.

the bearing has collapsed, lots of the balls have fallen out. That's what normally happens. Its an other engineered to fail part Merc can swap quick but hope to charge you 500 quid for.

We will see this come up a lot now they have clocked over 8 years

The pulley is fine the hub got taken out. All bits available separately Not sure if its damaged anything else, would be a shame as nice to keep a decent metal pulley. I have only seen plastic ones.


you could press out the bearing and get a proper quality one from a bearing factor. They might come in well under a tenner

The object he has removed is a one piece item that is threaded into the center section.

If he has removed this in 2 pieces (As per the picture where a piece is still attached to the threaded center section) , its broken.

Has anyone got any suggestions on how I can remove the A/C pulley from the last photo I posted.

I've removed the clutch mechanism I just want to remove the Pulley itself and Ill purchase a full new Clutch Assembly : http://euro-klima.pl/en/compressors-spare-parts/clutch-assemblies/#limit=45

Have you removed the belt?

Have you removed the belt?

Hi,

Yes I have removed the belt.
Will the center nut come off if I put mole grips round the moving part (Indicated with red arrow) whilst getting a socket on the nut? Or is the nut and center part all one part? Just asking before I damage it anymore.

 

[alexanderfoti]

Ah ok, the center threaded portion remains attacked to the compressor. IF you get mole grips on the outer bit (which appears to have broken free from its mate), hold the center piece still and rotate the broken outer piece (or vice versa)

Not getting what you mean? Sorry if i'm being thick.

When I turn the center part (indicated by red arrow) by hand nothing else turns so not sure what part you are talking abut holding with the mole grips?

I have removed the snap ring which I though would be holding in the bearing, the bearing slides back and forward a little but doesn't go over the lip!, or should it if forced??

WOOHOO!!

Ah.....I managed to get the center piece out, I gripped the center part (Indicated by red arrow in pic) with mole grips and turned the nut (Indicated by blue arrow in pic) clockwise. I noticed I was turning the nut the wrong way after coming across the following video: https://www.youtube.com/watch?v=iGAYh2x3WE4

I have removed the snap ring but the Bearing and Pulley don't slip straight out as I would expect it to.....so I will get a lone of my dads bearing pulley tomorrow to to see if that does the trick.

Good news! Give it a pull with a puller and it will come off, its likely fused to the shaft somewhat.

UPDATE:

I managed too renew the A/C Pulley very easily once I figured out how it came off, was a pretty easy fix really. I bought new clutch assembly off of eBay for only £45 so pretty chuffed

Hi guys, just been reading this thread. I think I have the same issue with my SL55 too as I have changed the inner belt tensioner and bearing as it was pretty bad plus both belts.

Ever since doing so I now can hear this clearly which wasn't hearable before. It's a very metallic sound of scraping and happens more or less constantly.

I'm pretty certain it's the A/C one as it doesn't turn very freely and squeaks when turned by hand.

Can anyone tell me where you get the new a/c clutch pulley part from please?

A link would be good as I cant seem to find anything on eBay. Cheers! Zain
