LOONG-GINE PARTS
This lock nut (Part No. V8171956) is specifically engineered for Dongfeng LoongGine Gearbox Assemblies, ensuring a perfect match with the original equipment’s dimensional specifications. Meticulously manufactured to align with Dongfeng’s strict quality standards, it eliminates issues like improper fitting or thread misalignment, directly replacing worn or damaged lock nuts in LoongGine-powered commercial vehicles (such as heavy-duty trucks and buses). Its precise thread pitch and outer diameter guarantee seamless integration into the gearbox assembly, maintaining the integrity of the transmission system’s operation

PRODUCT DESCRIPTION
High-Strength Material for Durability
Crafted from premium alloy steel with heat-treatment technology, the V8171956 lock nut boasts exceptional tensile strength and wear resistance. The material undergoes rigorous quenching and tempering processes to enhance its hardness (reaching a Rockwell hardness of HRC 35-40) and fatigue resistance, enabling it to withstand high torque, vibration, and extreme temperature fluctuations (-40°C to 120°C) during long-term gearbox operation. Unlike ordinary carbon steel nuts, it resists deformation, corrosion, and thread stripping, significantly extending the service life of the gearbox assembly
Anti-Loosening Design for Operational Safety
Featuring a specialized anti-loosening structure (incorporating a pre-locked thread profile or integrated friction washer, depending on the specific gearbox model), this lock nut prevents accidental loosening caused by continuous gear engagement and transmission vibration. The design creates consistent clamping force to secure critical gearbox components (such as input/output shafts and gears) in place, avoiding component displacement that could lead to transmission failure, abnormal noise, or even safety hazards during vehicle operation. It requires no additional locking devices, simplifying installation while ensuring reliable performance
Strict Quality Control & Performance Testing
Every V8171956 lock nut undergoes a comprehensive quality inspection process before leaving the factory, including dimensional accuracy testing (via coordinate measuring machines), material composition analysis, and torque load testing (on specialized hydraulic benches). Only products that meet 100% of Dongfeng’s quality criteria are approved for sale, ensuring consistent performance and reducing the risk of premature failure in heavy-duty operating conditions
Application-Specific Optimization for LoongGine Transmissions
Tailored to the unique operating characteristics of Dongfeng LoongGine gearboxes (which are widely used in long-haul trucks, construction vehicles, and urban buses), this lock nut is optimized to handle high torque loads during gear shifting and heavy payload operations. Its compact design fits within the limited space of the gearbox housing without interfering with adjacent components, while the smooth thread surface reduces installation resistance and prevents thread damage during assembly. Whether for OEM production or aftermarket replacement, it provides a cost-effective solution that maintains the original performance of LoongGine transmission systems
