Our specialization extends to a comprehensive range of spare parts for construction equipment , OEM replacement parts , heavy machinery components , diesel engine rebuild kits , hydraulic pump seals , and final drive repair kits .

To better assist our global partners, here are a few key engineering machinery parts definitions:

1. Piston (活塞 / Поршень): A reciprocating component in the engine that converts the expansion of gas into linear motion. Example: Doosan D1146 Piston ( 65.02501-0785 ) for a Doosan DX225LC Excavator.
2. Gasket Kit (垫片套件 / Комплект прокладок): A set of seals and gaskets used to ensure a tight seal during an engine rebuild. Example: Komatsu 6D125 Overhaul Gasket Kits ( 6153-K2-9900 ) for a Komatsu PC400-6 Excavator.
3. Cylinder Head (缸盖 / Головка блока цилиндров): The part that seals the top of the engine cylinder, housing the valves and spark plugs/injectors. Example: Hino J05E Engine Cylinder Head ( VH111014950A ) for a Kobelco SK210-8 Excavator.
4. Fuel Pump (燃油泵 / Топливный насос): Draws fuel from the tank and delivers it under pressure to the engine's injection system. Example: Volvo EC160B EC210B Fuel Pump ( VOE20917999 ) for a Volvo EC210B Excavator.
5. Water Pump (水泵 / Водяной насос): Circulates coolant through the engine and radiator to regulate temperature. Example: Caterpillar C15 Engine Water Pump ( 3520211 ) for a Caterpillar D8R Bulldozer.
6. Starter Motor (启动马达 / Стартер): An electric motor that rotates the engine to initiate its operation. Example: Cummins 6CT 8.3L Starter Motor ( 3957597 ) for a Hyundai R300LC-7 Excavator.
7. Belt Tensioner (皮带张紧器 / Натяжитель ремня): Maintains the correct tension on engine belts to prevent slippage and wear. Example: Caterpillar 345C Belt Tensioner ( 211-7895 ) for a Caterpillar 345C Excavator.
8. Final Drive (终传动 / Бортовой редуктор): The gearbox and hydraulic motor assembly that drives the tracks or wheels of the machine. Example: Hyundai R480LC-9 Travel Reduction Gear ( XKAH-01287 ) for a Hyundai R480LC-9 Excavator.
9. Turbocharger (涡轮增压器 / Турбокомпрессор): A device that uses exhaust gas to compress the air entering the engine, increasing power. Example: Caterpillar 318D2L Turbocharger ( 226-8771 ) for a Caterpillar 318D2L Excavator.
10. Solenoid Valve (电磁阀 / Электромагнитный клапан): An electromechanically operated valve used to control the flow of hydraulic fluid in systems like the swing or travel circuit. Example: Caterpillar 320C 320D Solenoid Valve ( 116-3526 ) for a Caterpillar 320D Excavator.

We also carry high-demand items like the Caterpillar 330D Water Pump ( 352-2123 ) and various Hyundai Harness assemblies ( 21N621033 , 21Q6-10704 ).

Our core business, Growshine International (格莳国际), is rooted in the export and import trade of heavy machinery parts , specifically high-quality replacement components for Komatsu , Caterpillar , Volvo , Hyundai , Doosan , and Cummins equipment. We manage a vast network to ensure access to a diverse array of products, from precision engine components like the SAA6D125 Fuel Injection Pump ( 6251-71-1120 ) to critical drivetrain parts such as the 320D2 Excavator Final Drive ( 480-6770 ). Our commitment to cost-effective spare parts , global parts supply , and international export solutions has made us a leader in providing reliable aftermarket construction parts across the globe. Our catalog is extensive, covering nearly every component your fleet needs, including specialized parts like the Isuzu 6WG1 Thermostat ( 1-13770080-1 ) and the Cummins 4BT Pressure Sensor ( 2872424 ). We are your one-stop sourcing solution for all off-road equipment parts .

A common issue in Caterpillar 320D excavators is a sudden loss of travel power or speed, often related to the final drive or hydraulic system.
Fault: Caterpillar 320D Excavator experiences weak travel or slow final drive operation (e.g., final drive part 480-6770 ).
Diagnosis & Solution: This can be caused by low oil in the Final Drive (Travel Reduction Gear) or a fault with the Solenoid Valve ( 116-3526 ) controlling the travel motor. Check the gear oil level and condition in the final drive; if metal particles are present, a complete rebuild or replacement of the Travel Reduction Gearbox may be needed (like the CX800 Travel Reducer Gearbox with part numbers KUA0281 and KUP10150 ). If the oil is clean, inspect the pressure settings and the function of the hydraulic travel solenoid valve. Replacement of the Caterpillar 320D Solenoid Valve ( 116-3526 ) is a common repair for hydraulic control issues. We stock all these heavy equipment replacement parts .
