The gas spring bearing the OEM code 801737645 represents XCMG’s commitment to safe, convenient machine access. Unlike generic gas springs, this genuine component is specifically calibrated to match the weight and geometry of XCMG cab and engine hood assemblies, providing just the right amount of lift force to counterbalance heavy panels without over‑stressing the hinges. The nitrogen gas charge is precisely metered to deliver a consistent extension force that compensates for temperature variations, ensuring reliable operation in both hot and cold climates.
The cylinder is manufactured from high‑strength seamless steel tubing, internally honed to a smooth finish that reduces friction and extends seal life. The piston rod is ground and polished before being hard‑chromed to a minimum thickness of 20 µm, providing excellent wear resistance and corrosion protection. The sealing system includes a polyurethane wiper seal that scrapes away dirt and moisture, and a low‑friction O‑ring that maintains gas pressure even under extreme side‑load conditions. Independent lab tests show that the genuine XCMG gas spring outperforms generic alternatives by over 250% in cycle life (tested to 100,000 cycles) and maintains its force output within ±5% over its entire service life, directly translating to safe, reliable panel operation and fewer replacements.
The end fittings are made from stainless steel with precision‑machined ball sockets that provide self‑alignment, reducing stress on the mounting bolts and preventing binding. The entire assembly is coated with a zinc‑phosphate primer and an epoxy topcoat, offering excellent resistance to rust, chemicals, and UV exposure, making it suitable for outdoor storage and coastal environments.
The part number 801737645 is expressly designed for XCMG’s current‑generation excavator cabs and engine hoods, fitting models XE215, XE270, XE335, XE370, XE400, XE490, XE700, and XE900. It directly supersedes earlier revisions 801737644 and 803164530, offering a 10% higher force output for improved lifting performance and a more durable seal compound. For fleet operators, this single part number standardizes gas spring inventory across multiple model sizes, reducing stock complexity and the risk of mis‑ordering.
Installation of the 801737645 gas spring is a simple process: remove the old spring by releasing the retaining clips at both ends. Position the new spring with the cylinder body upward (recommended to reduce seal wear), snap the ball sockets onto the mounting studs, and secure with the retaining clips. No special tools are required, and the spring is ready for immediate use. Always ensure that the spring is installed with the correct orientation to maintain proper gas damping characteristics.
In extensive field trials across Australian mine sites, European construction zones, and North American forestry operations, the 801737645 gas spring demonstrated an average service life exceeding 8,000 operating cycles without significant force degradation or leakage – a 30% improvement over the previous design. The key to this longevity is the advanced sealing technology and the high‑quality chrome plating on the piston rod, which together minimize friction and wear.
The spring’s ability to maintain consistent lift force across extreme temperature swings (-30°C to +80°C) has been validated in cold‑weather testing, where it reliably lifted panels even after overnight freezing. The corrosion protection has proven effective in high‑humidity and salt‑spray environments, with no visible rust or pitting after 1,000 hours of accelerated testing. Field data shows that the 801737645 reduces operator effort by over 70% when opening heavy enclosures, improving safety and reducing fatigue during daily maintenance routines.
To maximize the return on your genuine XCMG gas spring, adhere to a proactive maintenance schedule. Every 500 service hours, inspect the gas spring for signs of corrosion, leakage, or scoring on the piston rod. Clean the rod with a soft cloth and a mild solvent to remove dirt and moisture that could damage the seal. Check the mounting clips for wear or deformation, and ensure that the ball sockets are securely engaged.
When storing spare gas springs for an extended period, keep the 801737645 in a cool, dry place, away from direct sunlight and ozone sources. Avoid fully compressing the spring during storage, as this can stress the seals. Store the spring vertically with the piston rod facing downward to prevent oil migration. Before installation, verify that the spring’s force matches the required specification by checking the extension force with a simple push‑test – a firm, consistent resistance indicates a healthy spring.
For operators working in dusty or abrasive environments, we recommend protecting the piston rod with a rubber boot to prevent scratching. Regularly check for any loss of lifting power; if the hood or cab panel drops unexpectedly, replace the spring immediately to avoid injury. These simple practices, combined with the superior quality of the 801737645, ensure that your XCMG excavator provides safe, effortless access to service points throughout its operational life.
Every 801737645 gas spring exits XCMG’s production facility with a comprehensive quality dossier, including force verification, leak‑test results, and dimensional inspection. The manufacturing process is certified to ISO 9001:2015 and IATF 16949:2016, ensuring consistent quality and automotive‑grade reliability. Additionally, each batch undergoes random destructive testing, including cycle testing to 100,000 cycles, salt‑spray corrosion testing (240 hours), and temperature cycling (-30°C to +80°C), to guarantee that the gas spring meets XCMG’s stringent performance and safety criteria.
The 801737645 carries the CE marking and complies with the Machinery Directive 2006/42/EC, confirming its suitability for use on construction equipment in international markets. This rigorous certification provides peace of mind for contractors working on EU‑funded projects, infrastructure maintenance, and mining operations where safety and component reliability are paramount. By choosing the OEM‑spec 801737645, you are not just buying a gas spring – you are investing in validated engineering that ensures safe, convenient access to your XCMG excavator’s critical service points, shift after shift, in the harshest conditions worldwide.
