Replacing the hydraulic pump on the Mercedes R129 SL Class

This is a very easy to do job. These cars are getting older and if you haven't replaced your pump, you might consider getting it rebuilt.
I'm installing a rebuilt unit by @TopHydraulics in Florence, Oregon. Besides rebuilding the pump, they offer rebuilding services for all of the roof cylinders and the solenoids.

Thanks for watching

This is sort of what I mean by "a nightmare of German ingenuity." They've hidden it under the spare tire, which most people don't even know, and you need a special set of wrenches, which most professional mechanics don't even have, just to take it out, at which time you may very well find that Mercedes hasn't made the part for ten years. Try finding the plastic strip that holds in the headliner on a CLK430. Part of the joy of owning a Mercedes.

Very helpful video Thank You

I am a quant analyst, so I am doing a lot of coding. I have a plan to buy an early R129 and swap euro headlights and rebuild soft top mechanism. It is amazing for me to find you who do exactly what I want to do. Keep it up and I will follow your instruction in the near future.😊

Very good. I would recommend powering it up and checking the operation before replacing the access panels, tire etc., just to check for leaks before you button it all up.

you might want to disconnect the return line, put the hose into a bottle and then, cycle the top a few times to flush out all the old an dirty fluid. of course topping up the fluid also.

This is great advice to get a proper flush! Thanks 🙂

Good video. How did you find out that the pump was faulty?

[@bsclifton]

Hi there! The pump actually wasn't faulty (or I don't think it was). I just replaced as a preventive measure since the seals inside were likely old and tired. That's the trick with the hydraulics - make sure the seals are in good shape so that there are no surprises 🙂
