XCMG Motor Grader Hydraulic Motor 803010458
Part number 803010458 identifies a hydraulic motor listed for XCMG motor grader service. A hydraulic motor converts oil flow into rotary output, but the product record does not establish one universal installation position or one exact grader model. For safe parts matching, compare the complete label, shaft, mounting face, port arrangement and the machine identification plate.
Evidence-first ordering: Send photographs of the old motor from the label side, shaft end, mounting face and port side. Add the grader model and serial number. This is more reliable than choosing from appearance alone.
Identify the motor by interfaces
Hydraulic motors with similar housings may differ internally or use different shafts and ports. Part number 803010458 is the primary reference, while the original component and machine record provide the final confirmation. Do not infer displacement, rotation direction or operating pressure from a photograph when those values are not shown on the label.
| Reference part number | 803010458 |
| Equipment family | XCMG motor grader; exact model requires confirmation |
| Component type | Hydraulic motor |
| Critical match points | Label, shaft, pilot, bolt pattern, ports and case-drain connection if fitted |
Diagnose the hydraulic circuit before replacement
Low speed, weak torque, heat, noise or external leakage can justify inspection, but these symptoms do not prove that the motor is the only fault. Restricted filters, insufficient pump supply, air entering a suction line, control-valve leakage or contaminated oil can produce similar behaviour. Use the service information for the exact grader when checking pressure and flow, and never exceed specified test limits.
Pre-removal and installation checks
Clean the surrounding area and record every hose position before loosening connections.
Depressurise the system according to the machine procedure and cap all open lines immediately.
Compare shaft profile, effective shaft length, mounting pilot and bolt spacing.
Check each pressure, return and drain port for position and connection type.
Investigate contamination and service the specified filters before fitting the replacement.
Prime and commission the circuit using the approved procedure, then check leakage, noise and smooth operation.
Information for a useful quotation
Provide part number 803010458, the full XCMG grader model, machine serial number, quantity and destination country. If the identification plate is unclear, include close-up and wider photos so the complete mounting context can be reviewed. Avoid describing the unit only as a “GR215 motor” or another exact application unless the original evidence supports that conclusion.

FAQ
Which XCMG grader model uses 803010458?
The current product record states XCMG grader but does not provide a verified exact model. Confirm the machine serial number and original motor label before ordering.
Can rotation direction be determined from the housing?
No. Use the manufacturer label or verified service information. A visually similar housing is not reliable evidence of internal configuration.
Does a slow hydraulic function always mean the motor is worn?
No. Pump supply, oil condition, filters, control valves and line restrictions should be tested as part of the circuit.
What photographs should I send?
Send the complete label, shaft end, mounting face, all ports and the machine serial plate, plus one wider image showing where the motor is installed.
Compatibility note: Supply should be based on the 803010458 reference together with machine and interface verification.
