Rebuild & upgrade service for your Z4 convertible top pump, also known as Motor assembly or Hydro Unit. Your pump will ship back exceeding all manufacturer's specs. This is a full rebuild where the pump gets torn apart to the component level, all seals get replaced and upgraded, every component checked for tolerance and function and replaced as necessary. The pumps shipping from Top Hydraulics may not look as pretty as brand new ones but we are sure that they are better inside and will outlast new ones.
