Hi guys, i'm looking for a used or new hydraulic pump for the self-leveling suspension system on the rear of a 1991 560sel.

The body is w126. The part number is: 117 230 00 64

I found an used one on ebay: 560SEL 560SEC 190E 300TD Hydraulic Leveling Pump | eBay

Not sure if this is the right part or if it works. So i'm looking for some help here.

Thanks!

Mars
