Essential **CAT Filtration** and **Engine** Spares

A machine's lifespan depends heavily on the quality of its filters and core engine components. We stock crucial filtration parts like the **CAT Filter 140-2334** (Air Filter for **305.5**, **306** Mini Excavators), the **CAT Fuel Filter 1R-0751** for the **315** and **323** series, and the **CAT Oil Filter 1R-1808** suitable for the larger **385** and **390** models. The **Air Filter 131-8821** and its secondary, **131-8822**, are vital for **CAT 320D** and **323** machines. When it comes to the engine and cooling system, the **CAT C6.4 Intercooler/Radiator** for **320/323** models, and the **CAT C13 Intercooler/Radiator** for **345/349** are key to maintaining optimal operating temperatures, preventing costly failures. The **CAT 330/336 Water Tank/Radiator** is a prime example of the heavy-duty cooling solutions we offer.

**Undercarriage** and **Hydraulic** System Essentials

The **CAT Undercarriage** is the backbone of your excavator's mobility. We supply critical components like the **CAT 345/349 Track Roller 178-7293** and **Carrier Roller** sets, along with **Track Chains** for machines like the **CAT 365C/374D**, **320/323**, and smaller models like the **307/308**. Components like the **CAT 320 Idler/Front Wheel** and the **CAT 320 Drive Sprocket 8E9805** ensure smooth movement and minimal downtime. For boom stability and movement, we offer **Boom Pins/Shafts** for the **CAT 320/323** series and the large **CAT 330/336 Boom Pin 251-2542**.

**Hydraulic Power** is maintained with parts such as the **CAT 336D Hydraulic Pump 322-8733** and various high-pressure **Sensors** like the **434-3436 Pump Pressure Sensor** for the **320D2**. Our inventory also includes complete **Hydraulic Cylinder Assemblies** (e.g., **CAT 395-7264**) and crucial **Swing Bearings** (e.g., **CAT 320/323D Swing Bearing 227-6081**) and **Travel Motors** (e.g., **CAT 330/336 Rexroth A2FE107**).

Component Definitions for **Construction Machinery** and **Heavy Equipment**:

• **Swing Bearing** (回转支承): Installed in the central frame, it allows the upper structure (cab, boom) to rotate relative to the undercarriage. **CAT 345 Swing Bearing** (Катерпілер 345 Опорний підшипник повороту).
• **Idler** (引导轮): Located at the front of the undercarriage, it guides the track chain and adjusts tension. **CAT 320 Idler** (Катерпілер 320 Направляюче колесо).
• **Sprocket/Drive Tooth** (驱动齿/驱动轮): Connected to the **Travel Motor**, it drives the track chain to move the machine. **CAT 320 Drive Sprocket 8E9805** (Катерпілер 320 Ведуча зірочка 8E9805).
• **Hydraulic Pump Sensor** (液压泵传感器): Located on the main hydraulic pump, it measures pump pressure for system control. **CAT 320D2 Hydraulic Pump Sensor 434-3436** (Катерпілер 320D2 Датчик тиску гідравлічного насоса 434-3436).
• **Pin and Bushing** (销套): Located at the boom, arm, and bucket linkage points, they connect moving parts and allow articulation. **CAT 330 Boom Pin/Bushing** (Катерпілер 330 Штифт/Втулка стріли).
• **Intercooler** (中冷器): Located between the turbocharger and the engine intake, it cools compressed air to increase density. **CAT 320 C6.4 Intercooler** (Катерпілер 320 C6.4 Проміжний охолоджувач).
• **Radiator Core** (散热器芯体): Located in the cooling system, it dissipates heat from the engine coolant. **CAT D8R Radiator Core 163-4062** (Катерпілер D8R Серцевина радіатора 163-4062).
• **Fuel Injector** (喷油器): Located in the engine cylinder head, it precisely sprays fuel into the combustion chamber. **CAT 320 C6.4 Fuel Injector 326-4700** (Катерпілер 320 C6.4 Паливна форсунка 326-4700).
• **Water Pump** (水泵): Located on the engine, it circulates coolant through the engine and radiator. **CAT C7.1 Water Pump** (Катерпілер C7.1 Водяний насос).
• **Track Link Assembly** (链轨): The main component of the track chain, forming the continuous loop that moves the machine. **CAT 374 Track Link** (Катерпілер 374 Гусенична ланка).

Common CAT Excavator Fault and Solution:

Equipment: **CAT 320D Excavator**

Fault: The machine's engine suddenly shuts down during heavy load operation, and is difficult to restart immediately.

Possible Cause and Solution: This can often be due to a faulty **Fuel Pressure Sensor** or clogged **Fuel Filters**. Check the **CAT Diesel Filter 1R-0751** for excessive contamination. If the filters are clean, the **Diesel Pressure Sensor 320-3060** on the C7.1 engine may be failing, leading the ECU to cut fuel flow as a safety measure. **Solution:** Replace the fuel filters and verify the pressure reading from the sensor using diagnostic tools. Replace the sensor if necessary.
