XCMG Steering Pump 803000307 / QC2513-XZ

XCMG 803000307 and QC2513-XZ identify a steering hydraulic pump for compatible crane carriers. Rotation, drive and hydraulic interfaces must match the installed engine and steering circuit.

Identification and Matching

• XCMG number 803000307

• Pump code QC2513-XZ

• Rotation and drive shaft

• Inlet/outlet ports and orientation

• Mounting flange and carrier model

Application and Service Scenarios

Replace after confirmed low flow, internal wear, seal leakage or mechanical damage. Heavy steering may also result from low oil, suction leaks, steering gear, priority valve or cylinder faults.

Inspection and Installation

Flush contamination, prime the pump, confirm rotation and align the drive. Start unloaded, bleed the steering circuit and verify assist, pressure, noise and leakage through full steering travel.

Frequently Asked Questions

Does heavy steering prove pump failure?

No. Test the complete steering circuit.

Can QC2513-XZA substitute?

Do not assume; compare the full code and interfaces.

Why bleed the system?

Air causes noise, poor assist and possible pump damage.

Export Packing

Ports and shaft are capped and the pump is secured against corrosion and impact.
