reI have a Sumitomo Link Belt, LS4300EJ model, with a ruptured hydraulic pump. What I am looking for is the main pump rotor kit and shafts, OR a complete pump that will bolt straight on. My excavator has a Nissan engine, which seems to have a different bolt pattern on the flywheel housing than the Izusu powered machines, which seem to be more common. The pump is a Uchida- Hydromatik A8V107ES model. Wondering if anyone might have any tips as to where I might find some parts or if another more readily available pump may be able to be adapted. Mark
I have still been searching and at this time all I have come up with is heaps of replys from alibaba. Am trying to sift through the pile and see if I can find gem. Didn't think finding a few small parts could be such a drama. Mark
