Designed specifically for Howo/Sitrak truck parts, this high-strength fastener ensures perfect alignment, eliminates vibration-induced loosening, and withstands extreme torsional stresses. Whether you are performing a major overhaul or replacing a worn bolt, this part guarantees a secure, leak-free connection that keeps your driveline operating at peak efficiency. With precision-machined threads and superior metallurgy, it reduces maintenance frequency and provides peace of mind for fleet operators and owner-drivers alike.
The VG1500010101 is far more than a standard fastener; it is a precision-engineered component that meets and surpasses the most demanding OEM specifications for heavy-duty applications. Every aspect of its design, from the thread rolling process to the heat treatment cycle, is meticulously controlled to deliver consistent clamping force and resistance to fatigue. This ensures that the flywheel housing remains perfectly mated to the engine block, preventing misalignment that could lead to premature wear of the flywheel, clutch, or starter motor. This bolt features a special surface coating that provides excellent corrosion resistance, even in environments where road salt, moisture, and high temperatures are prevalent. With a proof load that exceeds industry standards, this fastener offers the strength and durability required for the most punishing operating conditions.
Metallurgical Integrity – Manufactured from high-grade alloy steel, this bolt undergoes a multi-stage heat treatment process that optimizes its tensile strength and ductility, ensuring it can withstand the high cyclic loads experienced in the flywheel housing application.
Precision Thread Rolling – The threads are formed using a precision rolling process that work-hardens the material, resulting in superior fatigue resistance and a smoother, more consistent thread profile for accurate torque application.
Corrosion Protection – A specialized zinc-flake coating provides exceptional resistance to rust and corrosion, ensuring that the bolt can be easily removed during future service intervals without seizing or galling.
Optimized Clamping Force – Engineered to provide a consistent and reliable clamp load, this fastener maintains the integrity of the flywheel housing seal and prevents oil leaks that can lead to costly downtime.
The exceptional performance of this product begins with its carefully selected raw materials. We use a high-strength, low-alloy steel that is specifically formulated to provide the ideal balance of hardness, toughness, and resistance to hydrogen embrittlement. This material is then forged and machined to exacting tolerances, ensuring that every bolt is identical in dimensions and mechanical properties. The manufacturing process includes a rigorous quality control regimen, with each batch being tested for tensile strength, yield strength, and hardness to verify compliance with the strictest OEM standards. This commitment to quality ensures that the VG1500010101 delivers reliable performance, bolt after bolt, in the most demanding heavy-duty applications.
In addition to its mechanical properties, this bolt features a specialized surface treatment that enhances its corrosion resistance and lubricity. This coating, applied using a state-of-the-art process, provides a uniform layer that protects the fastener from the corrosive effects of road salts, moisture, and engine fluids. The enhanced lubricity also ensures that the bolt can be torqued to the correct specification with minimal friction variation, leading to more accurate and reliable clamp loads. This attention to detail is what sets this part apart from generic fasteners and makes it the preferred choice for professional mechanics and fleet maintenance teams.
The VG1500010101 is specifically designed to match the thread pitch, length, and head configuration required for the flywheel housing on HOWO and Sitrak heavy-duty trucks, including popular models like the HOWO T7H, Sitrak C7H, and the new energy-efficient series. By adhering strictly to OEM specifications, this fastener eliminates the guesswork and fitment issues that are common with generic aftermarket bolts. It features the correct shoulder length and underhead radius to ensure proper seating and stress distribution, which is critical for maintaining the structural integrity of the flywheel housing connection.
Moreover, this bolt has been validated through extensive testing in collaboration with leading fleet maintenance programs, demonstrating its ability to maintain clamp load over thousands of operating hours. Its compatibility with standard torque tools and procedures makes it a straightforward choice for workshops that service a variety of truck models. When you stock this part, you are providing your customers with a genuine replacement that preserves the engine’s original performance and durability.
Installing this bolt correctly is essential for maximizing its service life and ensuring the integrity of the flywheel housing connection. Before installation, it is critical to clean the bolt holes in the engine block and the flywheel housing using a thread chaser to remove any debris, old sealant, or corrosion. The threads should also be lightly lubricated with a high-quality thread lubricant to achieve accurate torque readings and prevent galling. The recommended torque specification for this fastener is typically in the range of 180-200 Nm, but it is essential to consult the specific service manual for your engine model, as torque values can vary.
When torquing, it is recommended to use a calibrated torque wrench and to follow a star or cross pattern to ensure even clamping force distribution. After the initial torque, it is advisable to re-torque the bolts after a short period of operation, as this allows the gasket and mating surfaces to settle. Regular inspection during routine maintenance is also recommended, as any signs of loosening or corrosion should be addressed immediately. By following these best practices, you can ensure that this bolt provides a secure and long-lasting connection.
Each bolt undergoes a comprehensive quality assurance process that begins with the inspection of incoming raw materials and continues through every stage of manufacturing. We utilize advanced testing equipment, including tensile testers, hardness testers, and thread gauges, to verify that every fastener meets the strictest dimensional and mechanical specifications. This product is also subjected to accelerated corrosion testing in salt spray chambers, ensuring that its protective coating provides long-term resistance to the elements.
In addition to in-process inspections, we conduct final audits on random samples from each production batch to confirm that the fastener consistently meets or exceeds OEM requirements. This commitment to quality is reflected in the performance of our bolts in the field, where they have earned a reputation for reliability and durability.
