OEM 800166191 The XCMG Fuel Pump 800166191 is a genuine OEM fuel pump engineered to deliver diesel fuel at correct pressure and timing on XCMG hydraulic excavators.
Identified by part number 800166191, this fuel pump supplies the engine injection system with a steady, metered flow of clean diesel under all operating conditions.
It is manufactured from high-strength alloy steel and precision-machined components that resist wear, heat and fuel contamination.
Exact OEM mounting flange, drive coupling and port geometry guarantee a direct replacement without modification during repair.
By maintaining correct fuel pressure, this pump protects injectors, supports efficient combustion and extends engine service life.
The 800166191 Fuel Pump is machined from high-strength alloy steel with hardened internal components for excellent wear resistance.
Its precision plungers and delivery valves maintain accurate fuel metering at both low and high engine speeds.
Exact OEM mounting flange, drive coupling and port geometry allow a direct replacement without modification during repair.
The pump delivers steady fuel pressure, protecting injectors from damage caused by pressure fluctuations or fuel starvation.
An anti-rust coating and diesel-resistant seals protect the pump from corrosion and fuel attack, extending service life.
Because the pump is a genuine XCMG component, it preserves warranty coverage and maintains compatibility with other OEM parts.
Production starts with certified alloy steel and precision components that are checked for hardness, dimensions and fuel resistance before release.
Pump bodies and plungers are machined and ground on computer-controlled machines that hold clearances and surface finish to exact tolerances.
After assembly, each pump is calibrated on a test bench to verify flow rate, delivery pressure and timing accuracy.
Batch records let XCMG trace each 800166191 pump back to its raw material lots, so any quality issue can be identified quickly.
Sample pumps from each batch undergo endurance testing and pressure testing to prove long-term durability and stable fuel delivery.
A fuel pump draws diesel from the tank and delivers it to the injection system at the correct pressure and volume.
The 800166191 pump maintains steady fuel flow at both low and high engine speeds, supporting stable combustion.
Correct fuel pressure protects injectors, pistons and turbochargers from damage caused by lean or rich mixtures.
By preventing fuel starvation, the pump also reduces the risk of power loss and unplanned engine shutdown on site.
When the pump works correctly, the engine runs cooler and more efficiently, saving fuel and repair costs.
Inspect the pump during routine service for leaks, unusual noise or reduced power, and replace any worn unit with a genuine 800166191 fuel pump.
The 800166191 Fuel Pump installs with standard hand tools, keeping downtime and labour costs low during repair.
Park the excavator on firm level ground, shut down the engine, and allow the fuel system to cool and depressurize.
Disconnect the fuel lines, remove the old pump, inspect the mounting flange and drive coupling for wear, and clean all contact areas.
Fit the new pump into position, align the drive coupling and mounting holes, and hand-thread the fasteners.
Tighten all bolts to the specified torque, reconnect the fuel lines, and prime the system to remove air.
Start the engine at low idle, check for leaks and unusual noise, and run through full function cycles before returning to work.
Choosing the genuine 800166191 Fuel Pump pays back over time by preventing fuel starvation and injector damage.
A worn or failed pump can cause power loss, hard starting and injector damage, leading to costly engine repairs.
The durable construction of this pump keeps fuel delivery consistent over a long service life, reducing replacement frequency.
Reliable fuel delivery also extends the life of connected components such as injectors, pistons, turbochargers and the engine block.
Field data from large construction and mining fleets shows genuine XCMG fuel components reduce fuel-related downtime significantly.
The pump remains serviceable for years under normal operating conditions, removing the need for premature replacement and lowering inventory costs.
XCMG applies sustainable manufacturing principles to the 800166191 pump through recyclable steel content and energy-efficient processes.
The extended service life, often exceeding 10,000 hours in normal conditions, cuts material waste and lowers the environmental footprint.
Preventing fuel leaks also avoids soil contamination and fuel loss, which supports regulatory compliance and responsible site management.
Steel and rubber materials are free from restricted substances and comply with RoHS and REACH rules for safe handling and disposal.
Selecting genuine XCMG fuel components supports responsible equipment management while delivering superior operational reliability.
The precision-engineered design allows long, dependable service, which minimises resource consumption across the working life of the machine.
The 800166191 Fuel Pump is stocked in XCMG regional distribution centres across North America, Europe, Asia and Australia.
Every unit is wrapped with anti-rust protection inside a fitted carton, shielding it from impact, moisture and dust during transit.
For fleet-wide orders, XCMG offers volume pricing and consolidated freight options that reduce procurement costs and simplify inventory planning.

Every 800166191 Fuel Pump comes from an ISO 9001 and ISO 14001 certified plant with full material traceability from raw stock to packed product.
Incoming alloy steel and precision components are tested for hardness, dimensions and fuel resistance before release to production lines.
During manufacturing, plunger clearances, delivery valve settings, port positions and coating thickness are monitored continuously by trained operators.
Post-production checks include dimensional verification, flow testing and pressure testing to confirm each pump meets specification.
Sample pumps from each batch undergo endurance testing and thermal cycling to prove long-term durability and stable fuel delivery performance.
Only pumps that pass every quality gate are released, so you receive a dependable, high-performance fuel component every time.
Cheap aftermarket pumps often use lower-grade steel, poor machining or inaccurate calibration that leads to rapid failure.
Those shortcuts lead to fuel starvation, injector damage and unreliable performance in demanding construction and mining conditions.
