The OEM reference 819956364 identifies a high‑quality tooth tip designed specifically for XCMG excavator buckets and heavy‑duty digging attachments. This genuine component is the primary cutting edge of the bucket, engineered to penetrate hard materials such as rock, compacted soil, and frost while withstanding extreme impact and abrasion. Manufactured from premium alloy steel with a through‑hardened structure, the 819956364 tooth tip delivers exceptional wear resistance, high fracture toughness, and reliable performance across the most demanding excavation applications.
As a key wear component, this tooth tip directly influences the productivity and efficiency of the excavator by ensuring effective material penetration and reducing cycle times. The part number 819956364 is a direct OEM replacement, fully compatible with XCMG bucket tooth systems, and undergoes rigorous hardness, impact, and dimensional testing to meet ISO 9001 and CE quality standards.
When replacing a worn or broken tooth tip, choosing the genuine 819956364 guarantees a perfect fit with the existing adapter system, correct locking pin alignment, and the same metallurgical properties as the original equipment. The tip’s self‑sharpening design maintains effective penetration throughout its service life, while its resistance to bending and breakage reduces downtime and replacement costs. This combination of robust materials and precision engineering makes the 819956364 the definitive choice for fleet operators seeking maximum digging efficiency, productivity, and lowest total cost of ownership.

The 819956364 tooth tip is the result of XCMG’s extensive materials science and bucket‑tool engineering expertise. Its alloy composition is carefully balanced to achieve a unique combination of high surface hardness for abrasion resistance and a tough, ductile core to absorb shock loads and prevent catastrophic failure. This is accomplished through a controlled quench and temper process that develops a martensitic microstructure.
The tip’s geometry is designed for optimal penetration and self‑sharpening action. The curvature and wedge angle are optimized to reduce resistance during digging, allowing the bucket to fill more quickly and with less force, which translates to reduced fuel consumption and lower operator fatigue. The pin hole is precisely machined to ensure a snug fit with the adapter, preventing excessive play that can accelerate wear.
Each tooth tip is individually weighed, measured, and inspected for surface defects and dimensional accuracy. The production process is continuously monitored, with hardness testing performed on every batch to guarantee compliance with the specified Brinell range. The result is a highly consistent product that delivers predictable wear patterns and extended service life, critical for large‑scale operations where downtime is costly.
The 819956364 tooth tip is designed to fit the standard XCMG bucket tooth adapter system, compatible with all XCMG excavators from the XE215 through to the XE900 series. It replaces earlier part numbers 819956363 and 803164699, featuring an improved, more abrasion‑resistant steel grade and a refined nose profile that reduces material build‑up.
Installation is quick and simple: insert the tip into the adapter cavity, align the pin hole, and drive in the new locking pin. Ensure the pin is fully seated and that the tip is securely retained. Always inspect the adapter for wear before installing a new tip; worn adapters can cause premature tip loss. Replace the retaining pin and rubber lock every time the tip is replaced, as these components degrade over time.
Extensive field tests in granite quarries, limestone mines, and heavy clay dig sites have demonstrated that the 819956364 tooth tip significantly outperforms standard aftermarket tips. In side‑by‑side trials, the genuine XCMG tip delivered a 35% increase in wear life and a 50% reduction in breakage incidents compared to low‑cost alternatives. Operators consistently report that the tip maintains a sharp, penetrating edge well into its wear cycle, reducing cycle times and improving productivity.
The tip’s resistance to cracking under impact has been validated through drop‑weight testing, where it withstood impacts from a 4‑kg mass dropped from 2 metres without any visible damage. This toughness is particularly valuable when working in frost‑heaved ground or when encountering buried rocks. The consistent quality ensures that wear is predictable, allowing maintenance planners to schedule tip rotations efficiently, avoiding unplanned downtime.
To maximise service life, inspect the tooth tips before each shift for signs of excessive wear, cracking, or pin retention issues. Rotate the tips from the centre of the bucket to the outer edges to promote even wear, as the centre tips typically wear more quickly. When a tip is worn to approximately 60% of its original length, it is time to replace it.
Always use the correct locking pin and rubber retaining element for the 819956364 tip. Using worn or incorrect pins can allow the tip to shift, leading to accelerated adapter wear and potential tip loss. Store spare tips in a dry area, as moisture can accelerate surface corrosion if the protective oil film is removed.
In extremely abrasive conditions, such as silica sand or basalt, consider reducing the inspection interval to 100 hours. Keep a log of tip replacement intervals to track performance and identify any unusual wear patterns that could indicate misalignment or operator technique issues. By following these simple practices, you will obtain maximum value from each genuine XCMG tooth tip.
Every 819956364 tooth tip is supplied with a material test certificate that includes chemical composition, hardness traverse, and impact test results. The manufacturing facility operates under IATF 16949:2016 quality management, and all tips are 100% inspected for critical dimensions, including pin hole diameter and nose profile.
The product carries CE marking and has been tested to the appropriate standards for construction equipment attachments. Its design has been validated through extensive field trials and finite element analysis, ensuring it meets the demanding conditions of heavy excavator use. By choosing the OEM‑spec 819956364, you are investing in a tooth tip that has been engineered to deliver the highest level of performance, safety, and cost‑effectiveness for your XCMG excavator.
