OEM 803175558 The XCMG Hose Assembly 803175558 is a genuine OEM hydraulic hose assembly built to transfer pressurized oil between the main hydraulic components on XCMG excavators.
Issued under the official part number 803175558, this assembly gives the technician a correctly sized hose with the proper end fittings for its circuit.
The hose, crimp collars and fittings are assembled to the XCMG drawing, so the length, bend radius and port orientation match the machine.
A reinforced rubber core and braided layer absorb pressure pulses, so the assembly resists swelling and fatigue during repeated working cycles.
The outer cover resists oil, water, ozone and abrasion, so the hose keeps its strength through wash-down and long outdoor duty.
Every unit is pressure-tested and checked for crimp diameter, fitting alignment, bore cleanliness and cover finish before packing.
Fitted to boom, arm, bucket and travel circuits, this hose assembly keeps oil flowing cleanly and keeps the hydraulic system sealed.
The 803175558 hose assembly is produced to the XCMG drawing, so the hose length and fitting orientation match the machine on the first attempt.
A reinforced hose body absorbs pressure pulses, so the assembly resists ballooning and fatigue better than a low-grade replacement.
The correct bend radius keeps the hose clear of sharp edges and hot surfaces, which prevents rubbing and premature failure.
The outer cover resists oil, water, ozone and abrasion, so the hose does not crack or flake apart in outdoor service.
Because the assembly matches the OEM number, a fitter installs it straight from the box without cutting, crimping or adding adapters.
Correct crimp diameter keeps the fittings tight under pressure, so the hose does not weep or pull out at the collar.
A sound hose assembly also protects the pump and valve block, which keeps oil clean and service intervals predictable.
Keeping a spare hose on the shelf shortens repair time, so a burst line does not leave the machine idle and exposed.
Each lot begins with certified hose, fittings and crimp collars tested for bore, wall thickness and material chemistry before assembly.
Assemblies are crimped in controlled tooling, so the collar diameter, insertion depth and fitting angle stay uniform from batch to batch.
Deburring and cleaning remove sharp edges and debris from the fittings, so the hose seats cleanly and does not shed particles into the oil.
Inspectors measure length, crimp diameter, fitting alignment, bore cleanliness and cover finish against a gauge for this part number.
Batch records trace every 803175558 hose assembly to its hose lot and production run, so a quality question is settled quickly.
A hose assembly carries oil between components, so the machine can lift, dig and travel without losing pressure at the circuit.
A cracked or loose hose lets oil escape, which causes slow operation, overheating and unplanned downtime on site.
The genuine 803175558 keeps the circuit sealed, so internal parts stay lubricated and the hydraulic system stays clean.
Correct length and routing avoid both a hose that is stretched tight and one that loops and rubs against the frame.
A sound hose protects the pump, valve block and cylinders, which keeps service intervals predictable and extends machine life.
The 803175558 hose assembly is installed with a cleaning cloth, a spanner set and a torque wrench during service work.
Release system pressure, remove the old hose, clean the ports and check the threads so no dirt sits under the new fittings.
Check the frame and clamps for cracks, rust or sharp edges, since a damaged route will rub the new hose and shorten its life.
Lift the hose into place, follow the original route, start the fittings by hand and align the bends before final tightening.
Tighten to the torque in the service data, so the fittings seal without distorting the port or crushing the hose collar.
Run the machine and check for leaks, bulges or rubbing along the route, then confirm the hose is clear of hot and moving parts.
At service intervals, look for loose fittings, cracked cover or worn clamps and renew the part before oil is lost.
Every 803175558 hose assembly is produced in an ISO 9001 and ISO 14001 certified plant with traceability from hose to carton.
Incoming hose and fittings are tested for bore, wall thickness and thread quality, and finished units are gauged for length and crimp size.
Each batch is screened for cover cracks, fitting damage and crimp defects, since these flaws let the hose fail under pressure.
Post-production checks include visual review, dimensional verification and a proof pressure test on every assembly.
Sample hoses from each batch undergo impulse and salt spray tests to confirm strength and corrosion performance.
Cheap copies often use thin hose and rough crimps, so the assembly weeps, bulges or pulls apart at the fitting.
A hose with the wrong length or fitting angle can rub the frame, kink at the bend or leak at the port.
The genuine 803175558 is made to the XCMG drawing, so length, fittings, pressure rating and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM ports.
Backed by XCMG global quality standards and technical support, this hose assembly performs reliably in harsh conditions.
Choosing the genuine 803175558 hose assembly prevents a small leak from turning into a pump failure or a burnt cylinder.
A failed hose lets oil escape, which wears parts, raises heat and shortens component life.
A correctly crimped assembly holds pressure firmly, so it does not need repeated tightening and does not wear out the port threads.
Reliable hoses also keep the machine bay clean, which improves appearance and lowers ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
XCMG produces the 803175558 hose assembly with efficient cutting and crimping runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each hose.
Keeping the hydraulic circuit sealed prevents oil leaks, which protects soil, groundwater and internal parts.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 803175558 hose assembly is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each unit is capped to protect the fittings and boxed in a strong carton that guards against dust, damp and impact.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams cover urgent requests fast, so machines return to work sooner.
Careful packing keeps the hose straight and the fittings protected until fitting, avoiding kinks seen in loose storage.
