PERMCO Hydraulic Pump 1163134008I for XCMG QY50KA Crane

Part number 1163134008I is listed as a PERMCO hydraulic pump for XCMG QY50KA crane applications. The original label and physical configuration must be compared because pump rotation, shaft, port layout and section arrangement directly affect installation and hydraulic function.

Identification Checklist

• PERMCO label and part number 1163134008I

• XCMG QY50KA machine serial number

• Number and order of pump sections

• Drive-shaft type, diameter, spline or key details

• Mounting flange and pilot dimensions

• Inlet and outlet port threads, orientation and markings

• Rotation direction shown on the original pump

Application and Service Scenarios

The pump may be considered after testing confirms insufficient flow or pressure, excessive internal leakage, abnormal pump noise, shaft-seal leakage or physical damage. It may also be required during planned hydraulic power-unit overhaul. Slow crane movement alone does not prove pump failure because filters, suction restrictions, valves, cylinders and system settings can create similar symptoms.

Diagnosis Before Replacement

Check oil level and condition, suction hoses, inlet leakage, filters, drive coupling and relief settings. Inspect the removed pump and oil for metal debris. If contamination or component breakdown is found, clean and inspect the wider hydraulic circuit before installing a replacement; otherwise debris can damage the new pump.

Installation Considerations

Keep all ports capped until connection, fill or prime according to the applicable hydraulic procedure and confirm correct rotation before starting. Do not force mismatched flanges, shafts or hose connections. Initial commissioning should monitor leakage, noise, temperature and system response.

Export Packing

Ports are sealed, the shaft and mounting face receive impact and corrosion protection, and the pump is restrained in a reinforced case. The label identifies 1163134008I and the confirmed configuration.

Frequently Asked Questions

Can the pump be selected by the QY50KA model alone?

The model helps, but the label, serial number, shaft, rotation, sections and ports should be checked.

Does slow hydraulic movement always indicate pump failure?

No. Suction, filtration, valve, cylinder and pressure-setting problems can produce similar symptoms.

Why must the hydraulic circuit be cleaned after pump damage?

Metal or other debris left in the circuit can quickly damage the replacement pump and valves.
