OEM 813403869 The XCMG Hose Assembly 813403869 is a genuine OEM pre-made hose assembly that delivers hydraulic oil between components on XCMG hydraulic excavators.
Stamped with part number 813403869, this factory assembly arrives with crimped ends already fitted, so technicians bolt it into place without measuring or cutting hose.
The hose is built from oil-resistant synthetic rubber, reinforced with braided steel wire, then covered with an abrasion-resistant outer layer.
Exact length, bore size and end fitting angles match the XCMG drawing, so the assembly routes correctly and clears frame parts and hot components.
Crimped ends are pressure tested to the rated working pressure, so the joints hold tight and the line does not weep under load.
Every assembly is proof tested and dimensionally checked before packing, so the part you receive matches the XCMG specification exactly.
The 813403869 hose assembly arrives fully crimped, so there is no measuring, cutting or field crimping before installation.
Its steel wire braid resists pressure pulses, so the hose does not balloon or pull off the fittings under heavy digging loads.
The pre-formed route matches the OEM layout, so the hose clears the frame, boom and hot engine parts without chafing.
A tough outer cover shrugs off grit, oil mist and vibration, which are the usual reasons a working hose wears through.
Correct bore and overall length keep flow at the designed rate, so function speed and pressure stay within specification.
Crimped fittings hold the rated pressure without weeping, which protects the pump and keeps hydraulic response sharp.
Because the assembly fits straight from the box, a technician finishes the repair in minutes rather than rebuilding a hose.
Production starts with certified rubber compound and steel wire tested for hardness, tensile strength and oil resistance.
The hose is built on a mandrel matching the OEM route, then vulcanized so tube, braid and cover bond into one strong wall.
Crimping machines squeeze each fitting to a set diameter, and the crimp is measured to confirm the collar has closed correctly.
Inspectors check assembly length, fitting angle, bore and crimp dimensions against a checking fixture for this part number.
Batch records trace every 813403869 assembly back to its hose lot and crimp program, so quality questions close fast.
The assembly carries pressurized oil between fixed and moving components, giving the machine a flexible, sealed connection.
A worn or leaking hose drops circuit pressure, which slows boom, arm and bucket movement and strains the pump.
The genuine 813403869 holds pressure at the crimps and along the wall, so flow stays steady and the circuit stays clean.
Correct routing away from hot surfaces and moving parts prevents abrasion, which is a leading cause of hose failure.
A sound assembly protects pumps, valves and cylinders, which keeps cycle times and machine uptime predictable.
The 813403869 hose assembly installs with a wrench set and torque wrench during scheduled hydraulic service.
Release hydraulic pressure fully, stop the engine and place a drain pan under the fittings before loosening anything.
Remove the old assembly, then clean both ports and inspect threads, O-rings and sealing faces for damage or corrosion.
Set the new assembly along the OEM route, start both ends by hand, and never twist the hose to close a gap.
Tighten fittings to the specified torque, refit the clamps and confirm the hose cannot touch any other component.
Start the engine, cycle each function slowly, and check both crimps and the hose body for weeping or movement.
At service intervals, check clamps and look for cover damage, bulges or oil film at the fittings.
Every 813403869 assembly is produced in an ISO 9001 and ISO 14001 certified plant with traceability from hose lot to packed carton.
Incoming hose and fittings are checked for dimensions and grade, and finished assemblies are gauged for length, angle and crimp size.
Each assembly is proof tested above its working pressure, and the result is recorded against the batch number.
Post-production checks include visual inspection, cap fit and a trial installation on the XCMG hydraulic line fixture.
Sample assemblies from each batch undergo burst, impulse and salt spray tests to confirm long-term performance.
Cheap copies often use weak braid and poor crimps, so the hose bulges or blows off a fitting within a short time.
A hose with the wrong length or fitting angle kinks or stresses the port, which leads to seepage and repeat repairs.
The genuine 813403869 is built to the XCMG drawing, so bore, length, fitting angle and pressure rating match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps compatibility with other OEM components.
Backed by XCMG global quality standards and technical support, this hose assembly performs reliably in harsh conditions.
Choosing the genuine 813403869 assembly prevents a small weep from turning into an expensive pump or valve repair.
A burst hose drains the reservoir fast, which starves the pump and damages internal parts within minutes.
Sound braid and correct crimps keep the assembly working across a long life, which reduces replacement frequency.
Reliable hydraulic delivery also extends pump, seal and oil life, lowering the total cost of ownership for fleets.
Service records from construction and mining fleets show genuine XCMG hydraulic parts cut unplanned downtime.
XCMG builds the 813403869 assembly with efficient mandrel cycles and controlled crimping that keep material scrap low.
A long working life means fewer replacements, which lowers the raw material and energy tied to each assembly.
Containing hydraulic leaks protects soil and groundwater, helping operators meet rules on sensitive job sites.
The rubber and steel in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 813403869 hose assembly is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each assembly is capped and boxed in strong cartons that guard against kinking, dust and damp during transport.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams help cover urgent requests fast, so machines return to work sooner.
Careful packing keeps the assembly in factory condition until fitting, avoiding the cover damage seen in loose stock.
The XCMG Hose Assembly 813403869 is a key hydraulic part on XCMG excavators, linking components with a flexible, sealed line.
Its oil-resistant tube, steel braid and crimped ends deliver dependable pressure in hot, wet and dusty conditions.
