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.

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**.
