Undercarriage and Hydraulic System Integrity: Filters and Bearings

The integrity of your excavator's movement relies on top-tier **Undercarriage Parts**. We provide everything from Track Links and Sprockets (e.g., 422-8785 for 320C) to **Slew Bearings** like the 353-0680 for 330D/336D. Essential maintenance items include high-efficiency filters, such as the **Oil Filter 1R-1808** and **Hydraulic Return Filter 179-9806**, critical for hydraulic system cleanliness. Our expertise extends to mining equipment spares and heavy-duty vehicle parts, ensuring your machinery stays operational.

**Need-to-Know Part Definitions (Engineering Machinery & Heavy Truck Spares):**

• Hydraulic Cylinder GP (228-3499): A complete linear actuator converting hydraulic energy into mechanical force. Installed on the boom/stick/bucket. Example: CAT 345D Bucket Cylinder. Пример: Гидроцилиндр ковша CAT 345D.
• Slewing Bearing (353-0680): A large-diameter bearing that facilitates the rotation of the upper structure of the excavator. Installed between the carbody and the upper frame. Example: CAT 336D Slew Bearing. Пример: Опорно-поворотный круг CAT 336D.
• Pin Assembly (367-1461): A hardened steel pivot point connecting major assemblies like the boom and stick. Installed at joints of the work equipment. Example: CAT 390D Stick Cylinder Pin. Пример: Палец штока цилиндра стрелы CAT 390D.
• ECM (386-3444): Engine Control Module - the computer managing engine performance. Installed near the engine or in the cabin. Example: CAT 336D2 Engine ECM. Пример: ЭБУ двигателя CAT 336D2.
• Hydraulic Pump (315-4400): Converts mechanical energy into hydraulic energy to power all hydraulic functions. Installed on the engine flywheel housing. Example: CAT 336D Hydraulic Main Pump. Пример: Главный гидравлический насос CAT 336D.
• Turbocharger (461-3746): Increases engine power by forcing extra air into the combustion chamber. Installed on the exhaust manifold. Example: CAT C13 Turbocharger. Пример: Турбонагнетатель CAT C13.
• Final Drive (9Q-5696): The last gear reduction in the drivetrain, providing high torque to the tracks. Installed on the track frame. Example: CAT 330D Final Drive. Пример: Бортовой редуктор CAT 330D.
• Oil Pump (198-1508): Circulates engine oil for lubrication and cooling. Installed inside the engine block. Example: CAT C15 Engine Oil Pump. Пример: Масляный насос двигателя CAT C15.
• Fan Motor (247-8978): A hydraulic motor that drives the cooling fan. Installed near the radiator/cooler assembly. Example: CAT 374D Fan Motor. Пример: Мотор вентилятора CAT 374D.
• Water Pump (352-0206): Circulates coolant through the engine and radiator to regulate temperature. Installed on the engine block. Example: CAT C13 Water Pump. Пример: Водяной насос CAT C13.
