For professionals in the heavy-duty trucking industry, reliability is non-negotiable, and that starts with using authentic Shacman truck parts. Among the myriad of fasteners that hold these powerful machines together, the Double-Ended Bolt stands out as a crucial element. Specifically, the part numbered BY90003813571 is engineered to deliver unparalleled clamping force and vibration resistance in critical linkage points. This component ensures that pivotal assemblies, such as suspension connections, engine mounts, or chassis brackets, remain securely fastened even under the most strenuous operating conditions. Neglecting this part can lead to joint loosening, accelerated wear, and potential safety hazards, making it essential for routine maintenance and replacements.
Double-Ended Bolt
The BY90003813571 is a precision-engineered fastener designed exclusively for SHACMAN trucks. Unlike standard bolts, a double-ended bolt features threads on both ends, with an unthreaded shank in the center. This design allows it to act as a stud or a connecting rod, facilitating the secure attachment of two components from opposite sides. It is commonly used in applications where disassembly is infrequent, and a permanent or semi-permanent connection is required. The part is manufactured to meet strict OEM standards, ensuring exact dimensions, thread pitch, and tensile strength that match the original equipment.
In the context of SHACMAN vehicles, the Double-Ended Bolt BY90003813571 is often deployed in high-stress areas. For instance, it might be found securing leaf spring shackles, stabilizing sway bars, or mounting auxiliary equipment. Its role is to absorb dynamic loads and distribute stress evenly, preventing fatigue failure. The bolt’s construction from high-grade steel, combined with advanced heat treatment, provides exceptional resistance to shearing and stretching. This makes it a vital component for maintaining structural integrity over the truck’s lifespan.
Superior Material Quality: This bolt is forged from alloy steel, often grade 10.9 or higher, which undergoes quenching and tempering to achieve a tensile strength exceeding 1000 MPa. This ensures it can handle extreme loads without deformation.
Precision Threading: The threads on both ends are cut with high accuracy, guaranteeing perfect engagement with nuts or tapped holes. This minimizes the risk of cross-threading and ensures consistent clamping force.
Corrosion Resistance: A protective coating, such as zinc plating or dichromate treatment, is applied to shield the bolt from rust and chemical exposure, extending its service life in harsh environments.
Vibration Damping: The design incorporates features like a fine thread pitch or undercut shank to resist loosening caused by vibrations, a common issue in heavy-duty truck operations.
The BY90003813571 Double-Ended Bolt is versatile and used across various SHACMAN models, including the F3000, X3000, and M3000 series. Its primary function is to create robust connections in the suspension system, such as linking the spring leaves to the axle or connecting the shock absorber brackets. In the chassis, it may secure cross-members or support frames, ensuring rigidity and alignment. Additionally, it finds use in powertrain mounts, where it must endure constant engine vibrations and torque reactions.
Another critical application is in the steering linkage. Here, the bolt BY90003813571 helps attach drag links or tie rods, maintaining precise steering geometry. Its failure in this area could lead to unpredictable handling, posing safety risks. Furthermore, in vocational trucks used for mining or construction, this bolt is employed in equipment mounting points, such as for dump bodies or crane attachments, where reliability is paramount. Understanding these applications helps mechanics and fleet managers identify when replacement is needed during maintenance checks.
Regular inspection is crucial. Indicators that the BY90003813571 bolt needs replacement include visible thread damage, such as stripping or corrosion, elongation of the shank, or cracks near the heads. Looseness in connected components, unusual noises like clunking over bumps, or misalignment in suspension parts can also signal bolt failure. Addressing these signs promptly prevents costly downtime and accidents.
When installing the BY90003813571, always use a torque wrench to apply the manufacturer-specified tightening torque. Clean the threads and mating surfaces to avoid debris-induced stress. Apply thread-locking compound if recommended, and ensure proper alignment before tightening. Over-torquing can stretch the bolt, while under-torquing may lead to loosening. Refer to SHACMAN service manuals for precise procedures.

The part number BY90003813571 guarantees that the bolt meets all OEM specifications for dimensions, strength, and durability. Investing in genuine parts reduces downtime, avoids expensive repairs, and ensures compliance with safety regulations. For fleet managers, this translates to higher operational efficiency and lower long-term maintenance costs.
To extend the life of your BY90003813571 bolt, incorporate regular visual inspections into your maintenance schedule. Look for signs of rust, thread wear, or deformation. Clean the bolt and surrounding area during servicing to remove dirt and grime that can accelerate corrosion. If reusing the bolt, check its length and thread condition; replace it if any doubt exists. Always torque to the specified value using calibrated tools, and consider using thread sealants in wet environments. Document replacements to track part history and predict future needs.
Additionally, store spare bolts in a dry, cool place to prevent pre-installation corrosion. Educate technicians on the importance of using genuine parts like BY90003813571 to maintain vehicle integrity. By following these practices, you ensure that your SHACMAN truck remains reliable and safe on the road.
In summary, the SHACMAN Double-Ended Bolt with OEM number BY90003813571 is more than just a fastener; it is a critical component that ensures the structural cohesion and safety of your truck.
