[MBZ] 350 sdl a/c clutch r/r
Update on the removal an replacement of the a/c clutch on the 350 sdl. On this model you do not need a puller. You do need a large monkey wrench with some copper on each jaw ( to protect the pulley). You can then hold the pulley with the wrench while you remove the nut with a box wrench. You will need a right angle snap ring pliers- preferably the Hazet. Also you need a straight snap ring pliers that will open to at least 40mm. Snap On makes one and Hazet # 1845 A-19 should do the job- the tool is for the back snap ring. The normal snap ring tools are only 1-7/16 at the widest opening and will not (as I have found) make life pleasant. Some time ago I designed a series of mandrels for such problem installation in hydraulic machinery. Basically, you make a sleeve the i.d.which will match the o.d. of the shaft with a setback for the next o.d.. The o.d of the sleeve should be 1mm larger than the o.d of the shaft offset. You then transfer the seal or ring from the sleeve to the shaft. All of this is if you really want to solve a repeat maintenance item. Constantine

Constantine I replaced mine on a 300 SDL. I don't know if they are the same. I borrowed a removal and installation tool from Auto Zone that worked well. IIRC, I had to buy a snap ring tool to remove one inside the shaft area, PITA. I think you can find out on line if Auto Zone has the loaner tool you need and they may have a loaner snap ring tool.

Re: [MBZ] 350 sdl a/c clutch r/r
Some ND compressors need a pin wrench to counterhold the clutch so you can remove the center nut, but others have no provision for the pin wrench. In the latter case you can use channel-lock pliers. You'll need the MB pulling tool that screws into the center of the clutch, but some folks have had success prying it out slowly. I wouldn't try that though. -Aaron 1987 300D 1987 300TD On 12/12/05, Constantine N. Polites [EMAIL PROTECTED] wrote: Has anyone removed and replaced the a/c clutch?

You will need a pair of snap ring plier to remove a couple snap rings in order to remove the clutch bearing. The clutch plate will pop right off, no tool required (you do need the tools to get the seal out). Pulley presses onto the clutch, but I'm assuming you will get a new one. Peter
