ZF Oil Pump Housing Cover 1325 303 017 For ZF 16-Speed Ecosplit Manual Transmission

1325 303 017 is original OEM lubrication oil pump cover housing exclusively matched for ZF Ecosplit series 16-speed heavy-duty manual transmissions, compatible with 16S151NMV, 16S1930, 16S2220TO, 16S2230TO, 16S2530 full range gearboxes. This precision die-cast aluminum pump cover forms a closed hydraulic oil chamber together with pump gear and pump base, integrating molded suction & pressure oil flow channels to stabilize the lubrication system oil pressure. It fixes pump rotor, sealing O-rings and positioning shafts, continuously supplying clean lubricant to gears, synchronizers and bearings inside the gearbox. Long-term full-load transportation, contaminated gear oil and high-temperature aging will lead to flatness deformation, oil channel blockage and sealing surface leakage, resulting in insufficient lubrication pressure, gearbox overheating and abnormal grinding noise. Replacing this standard OEM pump housing fully restores stable oil supply circulation and eliminates internal oil leakage thoroughly.
