OEM 804017849 The XCMG Pilot Cooling Pump (804017849) is a genuine OEM hydraulic component engineered to circulate cooling fluid and maintain stable oil temperature on XCMG excavators. Identified by part number 804017849, this precision-built pump delivers reliable flow and pressure in the toughest construction, mining, and quarry environments.
Manufactured from high-strength cast iron and hardened steel internals, the 804017849 Pilot Cooling Pump offers outstanding wear resistance, pressure containment, and long service life. Its exact OEM mounting flange, drive coupling, and port positions guarantee a direct replacement without modification.
By keeping hydraulic oil at the correct temperature, this pump prevents overheating, reduces oil degradation, and protects pumps, valves, and cylinders from thermal damage during long working shifts.
The 804017849 Pilot Cooling Pump uses precision-ground gears that maintain tight clearance inside the pump body. This keeps volumetric efficiency high even after thousands of hours of service.
The cast iron housing resists deflection under high internal pressure. Bearing bores stay round, so the drive shaft spins smoothly without vibration or noise.
Hardened steel shafts and journals resist wear from contaminated oil. The pump therefore keeps delivering steady flow even in harsh working conditions.
Flange mounting and spline drive match the OEM interface exactly. Technicians can bolt the pump in place without shimming, alignment checks, or field modification.
By circulating cooling fluid continuously, the 804017849 pump prevents oil overheating and protects pumps, valves, and cylinders from thermal damage.
Production begins with certified cast iron blanks that are checked for chemical composition and hardness. Each housing is then machined to precise bore and face dimensions.
Gears and shafts are ground and lapped to tight tolerances before assembly. Backlash and end clearance are measured to ensure correct mesh and sealing.
After assembly, every pump is run-tested on a bench to verify flow, pressure, and noise levels. Units that fail any parameter are rejected before coating.
Final inspection includes leak testing, port alignment checks, and drive spline verification. Batch records allow XCMG to trace each pump back to its material heat numbers.
The result is a pilot cooling pump that performs predictably for thousands of hours on your XCMG excavator, season after season.
Hydraulic oil generates heat as it flows through pumps, valves, and cylinders. Without proper cooling, oil temperature rises and viscosity drops, reducing system efficiency.
The 804017849 Pilot Cooling Pump provides dependable circulation that keeps oil temperature within the design range, protecting seals and extending component life.
Field records from heavy excavation work show that machines fitted with genuine XCMG cooling pumps suffer fewer overheating faults and shorter diagnostic sessions.
The cast iron body and protective paint also resist moisture, dust, and chemical exposure, keeping performance stable across long service intervals in the field.
Inspect cooling pumps regularly for external leaks, noise, or reduced flow. Replace any compromised unit promptly with a genuine 804017849 component.
By keeping hydraulic oil at the correct temperature, this pump supports safe, productive excavator operation every working day.
The 804017849 Pilot Cooling Pump installs with standard hand tools, which keeps downtime and labour costs low during scheduled servicing or emergency replacement.
Park the excavator on firm level ground, lower the attachment, and release all hydraulic pressure. Lock out the machine so the engine cannot be started while work is in progress.
Drain the cooling circuit and disconnect the suction and delivery lines. Cap exposed openings immediately to keep grit and debris out of the hydraulic system.
Remove the old pump, clean the mounting flange, and fit the new unit with a fresh O-ring or gasket. Tighten fasteners in a diagonal pattern to the specified torque.
Refill with clean hydraulic oil to the correct level. Run the machine at low idle and check every joint for weeping, then recheck the oil level after warm-up.
During routine service, inspect the pump for leaks, unusual noise, or reduced flow. Replace any degraded component promptly to preserve hydraulic performance and avoid breakdowns.
Choosing the genuine 804017849 Pilot Cooling Pump pays back over time by preventing overheating, cutting diagnostic hours, and eliminating downtime caused by failed cooling.
A failed cooling pump can let oil temperature climb until seals harden and internal leakage rises, turning a small repair into a complete hydraulic system overhaul.
Across a typical 10,000-hour service life, the hydraulic system endures millions of heating and cooling cycles. The cast iron body of the 804017849 keeps performance consistent throughout.
Reliable oil temperature control also extends the life of connected components such as pumps, valves, and cylinders, reducing replacement frequency and total maintenance spending.
Field data gathered from large mining and construction fleets shows genuine XCMG cooling pumps cut heat-related downtime by as much as 16 percent.
The durable construction and quality coating keep the pump serviceable for years, removing the need for premature replacement and lowering lifecycle costs.
XCMG applies sustainable manufacturing principles to the 804017849 Pilot Cooling Pump through recyclable iron content and energy-efficient production processes.
The extended service life, often exceeding 8,000 hours in normal conditions, cuts material waste and lowers the environmental footprint associated with frequent replacements.
Preventing hydraulic leaks also avoids secondary damage and soil contamination, which supports regulatory compliance and responsible environmental stewardship on job sites.
Iron and paint materials are free from restricted substances and comply with RoHS and REACH rules, ensuring safe handling and disposal at end of life.
Selecting genuine XCMG hydraulic components supports responsible equipment management while delivering superior operational reliability and safety.
The precision-engineered design allows long, dependable service, which minimises resource consumption and waste generation across the machine’s working life.
