I have a 2001 IR SD100D vibratory roller. I have a broken propulsion pump and IR/VOLVO has made the pump and parts obsolete. The other option is several thousand of dollars to replace a whole pump for 1 small broken part. Does anyone know where I can get parts to repair it or a replacement pump? Who manufactured those pumps? Brand name/Model?
It's Sauer Danfoss 90 series, but you're going to need way more than a rotating group. That whole hydraulic system is trashed with contamination. You need to do a full cleanout and kidney loop. Everything that touches hyd oil in that machine needs cleaned/checked.
