power steering leak
looks like I've got a leak on the short hose between the reservoir and pump, but how do you get that hose off? Do I need to pull the reservoir? If so, where can I get a diagram on how that reservoir bracket is mounted to the block?
Thnks!
Thnks!

RE: power steering leak
I own a 1993 500SL. On a recent "free" checkup at a local dealer, they noted that the short power steering hose between the PS reservoir and the Power steering pump was leaking and needed to be replaced at a cost of $440. This seems outrageously high however it was explained to me that it was very difficult to do and required removal of the power steering pump among other things. Well, I am a DIY type of person and after a look it didn’t really seem too bad. In fact it proved to be fairly simple and roughly a 1 hour task – a bit tight working conditions for large hands but do-able. I hope that this proves useful to some fellow owner out there.
Here is what you need: (yes I am aware of the potential of using non-MB parts and fluids, however this makes it a one stop trip and I have run into issues before with OEM “equivalents” previously that far outweigh the few bucks extra cost of the MB parts) Pay attention to the hose clamp style – MB has 3 or 4 different designs. Select the ones with the smallest worm barrel and screw head. If you can avoid it – don’t use the ones with the two threaded posts as they take up even more room. Space is at a premium here and larger clamps are hard to position and reach. Do not substitute other types of hose as they have to hold up to constant exposure to PS fluid.
Part number QTY Description Cost
Q-1-46-0001 1 Power Steering Fluid $9.76
005-997-45-902 Hose Clamp$2.30
006-997-09-821 0.1m length Hose, Oil Cooler$4.25 *
007603-0201001 Ring, General (Al seal ring) $1.49
129-466-01-801 Gasket, Steering Reservoir $27.00
000-466-16-80 1 Gasket, PS Reservoir cover $3.44
119-997-00-45 1 Seal O Ring, PS Return hose $2.53
000-466-21-041 Power Steering Filter $17.22
* This MB hose is usually sold in 1M lengths for $42.50. The parts department was kind enough to sell me 1/10 M – enough to make two attempts to cut the hose right – more later.
I have seen the two expensive parts listed at various online MB OEM suppliers at lower costs if you can plan ahead. PS filter for $4.00 and reservoir gasket at ~$4.00.
Next there are a few special tools you will need in addition to standard combination wrenches and sockets.
1) 12mm allen wrench or allen Socket
2) E8 Torx socket
3) small vice grips
4) turkey baster
5) dental style mirror with pivoting head
6) flashlight
7) razor cutter or utility knife
The detailed proceedure I wrote is in the attached word document.

RE: power steering leak
backert1:
This is GREAT!! I've pulled the power steering reservoir assy thanks to SunGuy62's diagram and was in search of the parts, so this helps me figure out the parts!
OK, I hate to be a pain since I just got this car, but now all of a sudden the top won't go down. It worked when I bought it a couple of weeks ago, but now it just makes noise..feels like the rear deck wants to open, but just "pops" like it is stuck. Only the roll bar moves up and down. Any ideas?

I know this a two year old post I am replying to, but it it a new problem for me. I am a DIY guy and just bought a '93 500SEL. It has this problem. Your attached word document isn't attached any longer. If you still have the word doc hidden somewhere please attach once again. Thanks in advance.

dmckay111 & Skyjames,
The link I posted was to the MB Club of Russia who hosts a site with many of our car's systems. That link is indeed inoperative as the Club changed URL. The link below is to the new site, have your VIN#(all numbers and letters) handy to input to the small window at the top left of the page when you open the link, then press the button next to the window and if the club has drawings available for your car, they (sorted by ststems) will come up-
