The Connecting rod assembly (0001) is a precisely engineered component that links the piston to the crankshaft in the HOWO 7 6X4 Dump Truck engine, converting linear piston motion into rotational power. This assembly is designed to endure extreme pressures and temperatures, making its integrity vital for engine reliability. For a complete listing of all engine components and their specifications, refer to the Sinotruk Catalog which provides detailed cross-references and original equipment numbers.
The Connecting rod assembly (0001) is a complete unit consisting of the forged steel rod body, cap, bearing shells, and the critical fastening elements. The primary fastening component is the Connecting rod bolt, which secures the cap to the rod with a precise clamp load. This bolt is manufactured from high-strength alloy steel and is heat-treated to provide the necessary tensile strength and fatigue resistance.
The Connecting rod assembly (0001) features a carefully designed I-beam cross-section that balances strength and weight. The big end is split to allow assembly around the crankshaft, and the cap is retained by two Connecting rod bolts. These bolts are installed using a torque-to-yield procedure, which ensures that the bolts stretch within their elastic limit, maintaining a constant clamping force throughout the engine’s operating range.
Regular maintenance of the Connecting rod assembly (0001) includes inspecting the bolts for signs of thread damage or stretching. Replacing the Connecting rod bolts during an engine rebuild is a standard practice to prevent fatigue failure. Using genuine bolts guarantees the correct material properties and thread geometry, ensuring the assembly can withstand the high inertial loads of the reciprocating mass without loosening or breaking.
The Connecting rod assembly (0001) is balanced to within strict tolerances, reducing engine vibration and improving bearing life. Each assembly is matched to the specific engine weight class, ensuring that the rotating assembly remains in dynamic balance. This attention to detail contributes to the smooth operation and long service life of the HOWO 7 6X4 Dump Truck engine.
The Connecting rod bolt is a high-performance fastener specifically designed for the Connecting rod assembly (0001). It is made from chromium‑molybdenum steel with a rolled thread, providing superior fatigue strength compared to cut threads. The bolt features a reduced shank diameter that allows it to stretch elastically under torque, creating a consistent clamp load that maintains the bearing crush and prevents cap separation. Each bolt is supplied with a special lubricant to achieve accurate torque readings and is marked with a batch code for traceability. Proper tightening using a torque angle method is essential to ensure the bolt reaches its yield point without exceeding it, ensuring a reliable and durable joint.

Premium forged steel with controlled grain flow. Our Connecting rod assembly (0001) is forged from high-grade micro-alloyed steel, which aligns the grain structure along the rod’s shape. This enhances fatigue resistance and ensures the assembly can handle the peak cylinder pressures of the HOWO 7 6X4 engine without yielding or cracking.
Precision-engineered bolt with controlled yielding. The Connecting rod bolt is manufactured with a rolled thread and a specially designed reduced shank that ensures elastic deformation under torque. This provides a consistent clamp load that maintains bearing clearance and prevents cap movement, even after thousands of operating hours.
Advanced surface treatments for durability. The connecting rod is shot-peened to improve surface hardness and resist crack initiation, while the bolt is phosphate-coated to provide corrosion resistance and consistent friction properties. This extends the service life of the Connecting rod assembly (0001) and reduces the risk of premature failure.
Trusted by rebuilders and fleets globally. Our Connecting rod assembly (0001) components are manufactured under strict ISO quality standards, with each bolt batch tested for tensile strength and hardness. This ensures that every part delivers the performance and reliability expected by professional workshops and fleet operators worldwide.
