SINO CHOICE: Setting Sail with Premium Parts, Winning the Future with Superior Advantages
January 19, 2026. Meticulously prepared by SINO CHOICE, a shipment brimming with core components for Sinotruk and Shaanxi Heavy Duty Trucks stands ready to embark on its journey to global markets. These precision-engineered parts—akin to vital “heart components”—embody our unwavering commitment to quality and profound responsibility toward customers, delivering reliable assurance to overseas users of Sinotruk and Shaanxi Heavy Duty Trucks.
Today's Core Components: Exceptional Quality, Precise Compatibility
Power Transmission Essentials—Crankshaft Timing Gears, Fuel Injector Pumps, and Intermediate Gear Shafts
The crankshaft timing gear serves as the heart of the engine's valve timing system. Like a meticulous conductor, it precisely controls valve opening and closing cycles, ensuring seamless coordination between intake/exhaust processes and piston movement. SINO CHOICE's crankshaft timing gears are crafted from high-strength alloy materials, undergo precision machining and heat treatment, and exhibit exceptional wear resistance and fatigue strength. They deliver long-term stable operation in harsh environments, guaranteeing precise valve timing to enhance engine power performance and fuel efficiency.
The fuel injection pump gear serves as a critical transmission component in the fuel injection system, responsible for transferring engine power to the fuel injection pump to regulate fuel injection volume and timing. Crafted from premium materials and subjected to rigorous quality inspections, our fuel injection pump gears achieve optimal mating precision with the injection pump. This enables precise fuel injection, improving combustion efficiency and reducing exhaust emissions.
The intermediate gear shaft plays a vital supporting and transmission role within the engine's gear system, connecting multiple gears to ensure smooth power transfer. Our intermediate gear shafts are precision-machined with high surface finish and strict dimensional accuracy, effectively reducing friction and wear between gears. This enhances transmission efficiency and extends engine service life.
Engine Support and Protection — Main Bearing Shells, Crankshaft Thrust Plates, Oil Pan Assembly, and Fan Bracket Assembly
The main bearing shell is a critical support component for the engine crankshaft, bearing immense pressure and friction forces generated during rotation. SINO CHOICE's main bearing shells are crafted from high-performance alloy materials, offering excellent friction reduction and anti-seizing properties. They provide reliable support for the crankshaft under high-temperature, high-pressure operating conditions, minimizing crankshaft wear and ensuring normal engine operation.
Crankshaft thrust plates restrict axial movement of the crankshaft, preventing wobble during operation to maintain engine stability. Crafted from premium steel with specialized treatment, our thrust plates deliver high strength and wear resistance, effectively counteracting axial forces while preserving crankshaft positioning accuracy.
The oil pan assembly is a critical component of the engine lubrication system, serving not only to store engine oil but also to dissipate heat and provide sealing. Manufactured from premium metal materials and precision-engineered through advanced machining and welding techniques, our oil pan assemblies deliver superior sealing performance and corrosion resistance. This effectively prevents oil leakage, ensuring the reliable operation of the engine's lubrication system.
The fan bracket assembly supports the engine's cooling fan, ensuring stable operation to provide effective engine cooling. Constructed from high-strength materials with a robust structure, our fan bracket assembly withstands vibrations and impacts generated during fan operation, guaranteeing optimal engine cooling performance.
Piston Connecting Rod Assembly — Connecting Rod Assembly, Piston Pin, and Connecting Rod Bushing
The connecting rod assembly serves as the link between the engine piston and crankshaft, converting the piston's reciprocating motion into the crankshaft's rotational motion to deliver engine power. SINO CHOICE's connecting rod assemblies are forged from premium alloy steel, undergo precision machining and heat treatment processes, and feature high strength, rigidity, and excellent toughness. They withstand the immense alternating loads generated during engine operation, ensuring stable and reliable power transmission.
The piston pin is a critical component connecting the piston and connecting rod, enduring immense shear forces and impact stresses during piston reciprocation. Our piston pins are manufactured from premium steel and undergo surface hardening treatment, delivering high hardness, exceptional wear resistance, and superior fatigue performance. This ensures a reliable connection between the piston and connecting rod, minimizes wear, and extends service life.
Connecting rod bushings are installed within the small end bore of the connecting rod, working in conjunction with the piston pin to reduce friction and provide support. Crafted from high-performance alloy materials, our bushings exhibit excellent self-lubricating properties and wear resistance. They effectively minimize friction between the piston pin and connecting rod, reducing energy consumption and enhancing engine efficiency.
Since its establishment in 2009, SINO CHOICE has remained dedicated to the automotive parts sector. Through years of development, the company has accumulated extensive experience and robust capabilities. With a 5,000-square-meter parts warehouse, we maintain substantial inventory of diverse components to ensure timely fulfillment of customer demands.
In its operational model, the company employs a comprehensive and advanced system covering parts procurement, inspection, warehousing, sales, and service. Starting from the procurement stage, the company rigorously screens suppliers, collaborating only with reputable partners whose products meet reliable quality standards to ensure all procured parts comply with high-quality requirements. During inspection, the company utilizes specialized testing equipment and technical personnel to conduct stringent checks and tests on every batch of parts. Only components that pass inspection are admitted into warehouse storage. For warehouse management, the company utilizes an advanced inventory system enabling precise location tracking and rapid allocation of parts, thereby enhancing storage efficiency. The sales and service team possesses specialized knowledge and extensive experience, delivering comprehensive support including parts consultation, selection guidance, and distribution services to ensure customers receive timely and satisfactory assistance.
