XCMG XE2000 excavator exhaust valve guide 800169251 | Original factory fit, high temperature and wear resistant, ensuring stable valve transmission

In the valve system of the XCMG XE2000 excavator engine, the exhaust valve guide is a core component that guides the reciprocating motion of the exhaust valve, directly affecting valve sealing and engine power output. The XCMG XE2000 original exhaust valve guide (part number 800169251) is specifically designed for the high-temperature exhaust environment of the engine, precisely constraining the exhaust valve’s movement trajectory and preventing valve jamming and leakage caused by guide wear and deformation. This provides a solid “transmission defense line” for the efficient and stable operation of the XE2000 excavator engine.

800169251 Exhaust Valve Guide: Three Core Advantages, Compatible with XE2000

Original factory precise fit: The dimensions strictly follow the design standards of XCMG XE2000 engine valve system. The inner diameter accuracy (tolerance ≤ 0.005mm), length, and outer diameter fit dimensions are completely matched with the cylinder head and exhaust valve. No secondary processing is required for direct press-fitting, avoiding valve wobble and abnormal clearance caused by fit deviation, ensuring precise fit with the exhaust valve, and being compatible with the engine valve transmission rhythm.
High temperature resistance, wear resistance, and impact resistance: Made of high silicon molybdenum cast iron (silicon content ≥3.5%), and treated with high temperature aging, the high temperature resistance reaches over 450℃, which can withstand the high frequency friction and high temperature impact brought by the reciprocating motion of the exhaust valve; the surface hardness reaches HRC50-55, and the wear resistance is 80% higher than that of ordinary cast iron pipes, effectively reducing the wear of the inner wall of the pipe and avoiding poor valve sealing and power reduction caused by excessive clearance.
Corrosion resistant, durable and long service life: The material itself has excellent resistance to exhaust corrosion and can resist the erosion of acidic substances in engine exhaust. At the same time, the inner wall of the duct is precision honed (surface roughness Ra≤0.2μm), which reduces the frictional resistance between the exhaust valve and the duct and reduces the wear rate. The service life exceeds 15,000 hours (60% longer than ordinary ducts), reducing engine disassembly and repair due to duct failure, and reducing maintenance costs and downtime.

Suitable for multiple scenarios, with traceable quality, and safe to use.

Whether the XE2000 is operating under high-intensity conditions in mining (high engine load), heavy-duty construction in infrastructure projects (frequent start-stop), or running for extended periods in high-temperature environments, the 800169251 exhaust valve guide consistently performs its guiding function reliably. Each guide undergoes triple testing by XCMG (dimensional accuracy calibration, hardness testing, and high-temperature resistance testing), conforming to the ISO 8178 internal combustion engine valve guide standard and engineering machinery engine component specifications. It supports official traceability, ensuring safe and trouble-free use and preventing malfunctions such as valve erosion and abnormal engine noise caused by inferior guides.

Select 800169251, protect the XE2000 valve system.

If you are experiencing issues such as abnormal valve noise, exhaust leakage, or reduced power in your XCMG XE2000 engine, or if you need to replace an aging exhaust valve guide, the original factory exhaust valve guide (800169251) is the optimal choice. Its precise guiding performance ensures stable operation of the valve system, preventing damage to core engine components and helping the XE2000 continuously output power under various high-intensity operating conditions, thus facilitating efficient engineering work.
