For anyone who’s unlucky enough (like me) to have a leaking tandem PS pump, here are a few tips.

The seal kit “1 unit Power Steering / Tandem Pump Seal Kit Mercedes 0004608080” is virtually impossible to find, only one place (probably in the world) has them in stock - www.oldtimer-Ersatzteile24.de (€30)

Instead of buying The MB Pin Wrench (129589020700) for $159, you can manufacture your own tool by bending and cutting a thick nail

Removal is a pita, just find a vid/tutorial for any vickers pump, it will apply to you (less the SLS pipes)

The reseal procedure can be found on w124 performance from page 11
https://www.w124performance.com/service/w124CD2/Program/Chassis/46-0730.pdf

After I’ve removed the pump and ordered the kit, I’ve realized that the previous owner has cut (by the steering box) and closed looped the SLS lines… FML. Could’ve just gotten a normal PS pump from my local spares guy and resealed it using the seal kit I mistakenly bought

Good luck

Okay, I’ve asked before and no one seemed to know so I’m giving you guys the beans on how to find the correct part numbers, assembly diagrams etc to make your lives easier.

Catcar.info/en/ - for getting part numbers, assembly diagrams etc - can search for your car by VIN

w124performance.com/service/Main.html - for maintenance articles (installations, repairs etc)

pelicanparts.com/techarticles/MBZ_Tech_Index-W124.htm - for step by step instructions on multiple repairs/maintenance items (with images)

Spareto.com - quality parts supplier with very reasonable prices based in Estonia, can search by car model or part number (trusted and has reasonable worldwide shipping rates - significantly cheaper than my local stealership)

** Just a note on CatCar - if you can’t find a category (like transmission), select a different region for your car (eg, check the AUS version instead of US)

I’ll add some here if I think of anything else. Hope this helps. Cheers
