Parker P3145 Main Hydraulic Pump for XCMG QY70K
The Parker P3145 is listed as a main hydraulic pump for compatible XCMG QY70K cranes. Pump family alone does not define displacement, controls or interfaces; the complete nameplate must be compared.
Identification and Matching
Complete Parker P3145 nameplate code
QY70K serial number and hydraulic schematic
Rotation direction and drive shaft
Inlet, outlet, drain and control ports
Mounting flange and control arrangement
Application and Service Scenarios
Replacement may be considered after confirmed internal wear, case-drain excess, inability to build flow/pressure or mechanical damage. Suction restriction, contaminated oil, relief settings, control faults and downstream leakage can mimic pump failure.
Inspection and Installation
Flush contaminated circuits, prime the pump, fill the case where required and verify rotation before starting. Begin at low load, monitor pressure, case drain, noise, temperature and leakage.
Frequently Asked Questions
Is P3145 alone enough to order?
No. The complete suffix and interfaces must match.
Does low pressure always mean pump failure?
No. Test suction, relief and downstream leakage.
Why is priming important?
Dry startup can damage the pump immediately.
Export Packing
Ports are capped, shaft and controls are immobilized, and the pump is secured in a reinforced export crate.
