803083409 XCMG LW600FV Tandem Hydraulic Steering Gear Pump

803083409 XCMG Tandem Steering Hydraulic Gear Pump

Olive Branch Hydraulics supplies the 803083409 replacement tandem hydraulic gear pump for XCMG wheel-loader applications. This product is identified by its material number, complete model reference and installation configuration. The primary equipment reference is LW600FV. The model HPT3-80/P124-10/Y030R also appears in replacement-parts catalogues for ZL60GV, with related LW600KN assembly references. Match the machine serial number and original pump before ordering.

Part Numbers and Model References

Equipment Applications

Equipment names help locate the correct replacement, but different production batches can use different hydraulic arrangements. A match in a parts listing is the starting point for identification. Before installation, compare the flange pilot, bolt centres, shaft length, spline dimensions, rotation direction and inlet/outlet positions with the removed pump.

Construction and Hydraulic Function

The illustrated configuration has two mechanically coupled gear-pump sections driven through one splined input shaft. Its external ports connect the sections to the machine hydraulic circuits. Separate sections must be identified correctly when reconnecting the hoses. The front mounting flange and shaft transmit the machine drive, while the pump body and rear section contain the gear sets and fluid passages. Follow the machine service instructions for circuit identification and commissioning.

Technical Selection and Flow

Parts listings describe a 14-spline shaft for this model reference. Confirm that count and the shaft diameter on the actual supplied unit. The numbers 80 and 10 occur in the model code; they should not be used as certified displacement values without the configuration datasheet. Continuous pressure, intermittent pressure, maximum speed, oil viscosity and operating-temperature limits also require confirmation for the supplied pump.

Flow depends on displacement, shaft speed and volumetric efficiency. With a verified displacement in cm3/rev and speed in rpm, theoretical flow in L/min equals displacement multiplied by speed and divided by 1,000. Actual delivered flow is lower and varies with pressure, fluid temperature and condition. Machine relief settings do not establish the pump pressure rating.

Information Needed for a Replacement Quote

Send the material number 803083409, the complete original pump model, machine model and serial number. Include clear photographs of the nameplate, shaft end, mounting face and both sides of the pump. Provide the flange pilot diameter, mounting-hole spacing, shaft projection and port measurements when the label is unclear. These details allow the replacement configuration to be checked before shipment.

Frequently Asked Questions

Is 253008148 the same as 803083409? Parts catalogues link them, but 253008148 can identify an assembly while 803083409 identifies the pump. Confirm whether mounting hardware or other components are included.

Does this pump fit every LW600-series loader? No universal fitment is claimed. LW600FV, ZL60GV and LW600KN references must be checked against the individual machine configuration.

How should I request this product? Use 803083409 XCMG steering gear pump or the full HPT3-80/P124-10/Y030R model, and attach original-pump photographs for configuration matching.
