XCMG GR215 Hydraulic Pump 101000146 / 1121302384 / 803045341

This hydraulic pump is listed for the XCMG GR215 motor grader with references 101000146, 1121302384 and 803045341. Multiple numbers can reflect catalog, supplier or assembly references, but the page alone does not prove that every similarly marked pump is interchangeable. Confirm the complete old-pump label and all mechanical and hydraulic interfaces.

Best enquiry evidence: Provide the GR215 serial plate plus clear images of the pump nameplate, drive shaft, mounting flange and every port. If two numbers appear on the old unit, photograph both without cropping.

Three references require one physical match

Start with the number visible on the removed pump and compare it with 101000146, 1121302384 and 803045341. Then check the drive interface, direction information shown on the label, pilot diameter, bolt pattern, inlet and outlet position, and any drain or control connection. Do not assume that a matching housing guarantees matching internal configuration.

Use operating symptoms as diagnostic clues

Slow blade movement, weak hydraulic response, heat or noise can lead to a pump inspection, but they are not pump-specific symptoms. Low reservoir level, unsuitable or contaminated oil, suction leakage, restricted filtration, worn cylinders and control-valve leakage may create similar results. A technician should follow the GR215 service procedure for pressure and flow testing before replacement.

Pre-installation checklist

• Record when the fault occurs: cold start, hot oil, idle speed, high engine speed or under a specific load.

• Inspect the reservoir, oil and filters; identify the source of any debris before installing another pump.

• Compare shaft profile and length, mounting pilot and bolt spacing without forcing the fit.

• Mark and photograph all hoses, then cap disconnected lines against dirt and moisture.

• Use the specified seals and approved priming procedure; do not operate a dry pump.

• After installation, inspect for leakage and abnormal sound before applying normal working load.

How to request a quotation

Send the three listed references, the number actually visible on the old pump, GR215 serial number, requested quantity and destination country. Include close and wide photographs. If one reference comes only from a parts list rather than the pump label, state that clearly so the supplier can separate catalog evidence from physical evidence.

FAQ

Are 101000146, 1121302384 and 803045341 automatically interchangeable?
They are grouped in this product record, but final supply still requires comparison with the original label and physical interfaces.

Is this page specific to the XCMG GR215?
GR215 is the listed model. Confirm the machine serial number because production configurations may vary.

Can noise alone confirm pump failure?
No. Air entry, restricted suction, oil condition and connected components can also cause noise. Diagnose the complete hydraulic circuit.

What photos are essential?
Send the nameplate, shaft end, mounting face, port side and GR215 serial plate, with all markings readable.

Compatibility note: Use the listed references together with serial-number and interface verification before ordering.
