dissembling R4 compressor
Anyone have an exploded view of an R4 compressor or info/ pics of disassembly process?
I don't like the sound of the bearing on the R4 from my 240D parts car and would like to replace the bearing before using it.

The chances of any normal human being having all the special tools to do this correctly is zero... I have the MB AC manual with the take apart procedure..
but my scanner is not set up at this time.... if you take my word on it it will save you a lot of time and effort... find a good new one and install it correctly.. meaning full flush before hand.. you know all the rest of the ' drill '... and do not hit it with any sticks...

It's the bearing on the freewheel pulley that is a little noisy, not the compressor. I got the rusty center nut off of the practice R4 from the 300DT (with a bad solenoid coil) with Freeall penetrating oil, 3/8 breaker bar, 14 mm socket and impacted it off with a rubber mallet. I am going to Autozone and see if they have a puller that will fit. Hope the bearing in there is standard off the shelf.

We already have one forum member who recently paid a 'reputable Benz shop' a small fortune to fix his A/C and it is a dismal mess. The dealers I worked for DID NOT have the tools and they frequently borrowed them from the local GM dealer, or actually sent the MBZ's to the GM dealer and farmed out the compressor work. You can make the band removal tool, as I have outlined. You can buy the tool to remove/install the clutch online. The snap ring pliers are cheap. Once the clutch and coil have been pulled, the front hub is retained by 4 bolts. Take it off so you do not gouge the shaft by pushing the seal out from the backside. Nothing will fly out at you. Get a GM shop manual. The 1975 Pontiac FSM has a very simple and detailed overhaul protocol, much more clear than the MBZ manual. As always, my tech support is free via PM or E-Mail. Best of luck...Robert

I dont think the OP is off the title at all.....Just maybe not to the degree that you were thinking....so perhaps "misleading" to some.
I would think that in order to disassemble the compressor, one would need to remove the clutch assembly. I too am interested in this info as I have a noisy clutch assembly on my W123.

I have seen the pictures of taking the actual R4 apart .... EEEEEEKKKKKK !!!!!!
Well, I will modify that.. normal people can take it apart just fine.. putting it back together and it working a reasonable time... that is different...

I got a puller from Autozone. Set it up to pull on the pulley against the center bolt. Did not budge! Is the oulley not what I should pull on? Do I have to remove the 6 staked 8 mm bolts on the perimeter of the solenoid?
Leathermang, instead of posting about normal and abnormal people, how about posting some pertinent info from the Mercedes AC manual that you have?

Thanks whunter just the info I need!!! Good you are not a teaser like the leather guy.
 Went back to Autozone and they don't have the puller with the correct threads. They have one for the Ford but not for the GM R4.
