XCMG QY70K Main Hydraulic Components 20100603 / 20100604
References 20100603 and 20100604 are listed for main hydraulic components used in compatible XCMG QY70K systems. Because the original title does not define every variant, the complete component label, function and interface should be documented before supply.
Identification and Matching
Reference 20100603 or 20100604
Full component nameplate and manufacturer
Installed circuit position and function
Ports, mounting and control connections
QY70K serial number and hydraulic diagram
Application and Service Scenarios
Relevant during verified repair of the associated main hydraulic circuit after leakage, pressure/flow loss or physical damage is isolated to the component. Pump, valves, controls and actuators should be tested as a system.
Inspection and Installation
Keep all connections clean, compare port functions and mounting, flush contamination and follow the circuit-specific bleeding and commissioning procedure.
Frequently Asked Questions
Are 20100603 and 20100604 interchangeable?
Do not assume so; compare their exact function and interfaces.
What information prevents misidentification?
Send labels, full component photos and circuit position.
Should the circuit be flushed?
Yes when contamination or internal damage is found.
Export Packing
Every port is capped and each reference is separately labelled and secured for export.
