I'm trying to revive an old Prime Mover Skid Steer L1200D . Got all the books and part #s. Their just not on the self. It has a QD-40, 3AB1 Isuzu diesel, Sundstrand hydrostatic series 18, Ross TRW motors, the implement pump is a Rexroth S15S series which I need parts for. I've got old #'s . I would like to rebuild this pump. I just can't find the source. I done a lot of research Eaton and other companies have taken them over. Just try to bring this machine back to life. It works find ,Engines strong, No stress on mechanic, all but the pump is wore out could be fixed with a kit or Rexroth part thrust plate, wear plate and a seal kit . I've got the #.Just don't know where they are. Any Help Thanks
