Global equipment owners and maintenance providers constantly seek reliable, cost-effective alternatives for essential components like the Caterpillar Main Bearing 317-8766 (or 3178766) and various O-Ring seals. Growshine International, a leading Chinese export company, specializes in the procurement and supply of high-quality construction machinery parts, heavy truck spare parts, agricultural equipment components, and auto parts. Our mission is to provide global customers with premium Chinese replacement parts, ensuring excellent performance without the premium price tag. We manage the entire import and export trade process, from sourcing high-precision components like the Steel Backed Copper Lead Main Bearing to complex assemblies like the Engine Oil Pump 20R-1516 (or 20R1516).
Our extensive product list includes critical engine parts such as Cylinder Liners 197-9322 (1979322), Inlet Valve 122-0322 (1220322), and Exhaust Valve 122-0321 (1220321), which are essential for engine overhauls. We guarantee parts that meet strict quality standards for durability and fitment.
Sealing Solutions and Engine Bearings – Precision in Every Component
Engine reliability hinges on the quality of its seals and bearings. We offer a wide variety of sealing solutions, from high-performance 70A EPDM O-Rings like 6L-9405 (6L9405) to robust 78A HNBR O-Rings and FKM O-Rings (6V-8676, 6V8676). Our inventory also covers key engine bearings, including the crucial Main Bearing 317-8766 (3178766), Connecting Rod Bearing 328-5574 (3285574), and the Thrust Plate 253-1752 (2531752). These are critical engine internal parts and finding a reliable replacement engine bearing supplier is paramount for longevity. Growshine ensures that every part, from the smallest Seal-O-Ring 6V-5266 (6V5266) to the Cylinder Block Bearing 4N-6658 (4N6658), is manufactured to rigorous specifications. For specialized applications, our Gasket Kits, such as the Liner Gasket Kit 160-9874 (1609874), provide everything needed for a complete, leak-free assembly. We are a reliable global parts exporter for all your heavy equipment maintenance needs. You can view our comprehensive Caterpillar Product List here.
Filtration, Valves, and Sensor Technology
Modern engines rely on sophisticated filtration and sensor technology. Growshine International provides top-tier replacements for essential maintenance items, including the High Efficiency Fuel Filter 1R-0755 (1R0755) and the Engine Oil Filter 1R-1808 (1R1808). Furthermore, we supply crucial control components like the Fuel Bypass Valve 139-6873 (1396873) and the Pressure Control Solenoid Valve 107-0677 (1070677), ensuring optimal engine operation. We are your trusted solenoid valve distributor and OEM quality filter supplier. Our sensor range is also extensive, featuring various Temperature Sensors (238-0112, 2380112) and Pressure Sensors (274-6717, 2746717; 194-6725, 1946725), vital for accurate engine management. For specialized needs, our hydraulic components sourcing is second to none; explore our Hydraulic Products and Hydraulic Pump Components for related applications. We are also a strong source for genuine alternative auto parts, heavy duty truck engine components, and reliable agricultural machinery spares.
Chassis, Cooling, and Mechanical Overhaul Kits
Beyond the core engine, we provide essential supporting components. Our inventory includes Mounts like the Flanged Bushing Isolation Mount 4S-5367 (4S5367) and the Resilient Flexible Mount 343-4837 (3434837), crucial for vibration damping in off-road machinery. Cooling system components, such as the Engine Water Temperature Regulator 248-5513 (2485513) and the Main Water Pump Rebuild Kit 377-7037 (3777037), are readily available. For mechanical drivetrain components, check out our Garrett Turbocharger List and KALMAR Product List for related power and handling parts. When dealing with diesel engine maintenance, unexpected issues can arise. For example, if a Cat 3406 engine experiences continuous oil pressure fluctuation, a common cause might be a worn-out Oil Pump Drive Gear 155-6637 (1556637) or a faulty Engine Crankcase Breather 4N-4668 (4N4668). Our precise replacement parts offer the detailed solution required for complex fixes. We are a complete industrial engine component provider.
