Dimensions and reference weight are third-party catalog values for 7021319, not measurements of this aftermarket stock item. Do not use them alone to determine mounting clearance. Confirm shaft profile, flange and bolt pattern, inlet/outlet port size and orientation, rotation direction, displacement and required pressure rating against the original pump before fitting. These hydraulic performance values have not been established for this supplied unit.
Installation should be performed by a qualified technician following the machine service manual. Relieve hydraulic pressure, maintain clean connections and check the drive coupling, oil condition and system fault before replacing the pump.
