Each hydraulic pump, remanufactured at our company has its' own identity card with parts register, that have been used for remanufacturing. If the measurement didn't fit in the tolerance field the parts need to be exchanged. (a standard remanufacture doesn't include potential exchange of rotor, outer rotor's ring, clutch shaft, housing).
