Component Explanations for Machinery Experts
Water Pump (Engineering Machinery): Circulates coolant to regulate engine temperature. Example: Komatsu PC200-8 Water Pump - 沃尔沃 EC210B 水泵 - Насос водяной Komatsu PC200-8.
Brake Caliper (Heavy Truck): Houses the brake pads and pistons, crucial for stopping the vehicle. Example: Freightliner Cascadia Brake Caliper - 东风 天龙 制动钳 - Тормозной суппорт Freightliner Cascadia.
Hydraulic Filter (Agricultural Machinery): Removes contaminants from the hydraulic fluid. Example: John Deere 8400R Hydraulic Filter - 约翰迪尔 8400R 液压滤清器 - Гидравлический фильтр John Deere 8400R.
Throttle Body (Automotive): Controls the amount of air flowing into the engine. Example: Toyota Camry 2.5L Throttle Body - 丰田 凯美瑞 2.5L 节气门体 - Дроссельная заслонка Toyota Camry 2.5L.
Track Roller (Engineering Machinery): Supports the weight of the excavator or bulldozer and guides the track. Example: Caterpillar D8T Track Roller - 卡特彼勒 D8T 履带支重轮 - Опорный каток Caterpillar D8T.
King Pin Kit (Heavy Truck): Connects the steering knuckle to the axle beam, allowing the wheels to pivot. Example: Kenworth T800 King Pin Kit - 解放 J6 主销套件 - Комплект шкворня Kenworth T800.
Fuel Injector (Agricultural Machinery): Sprays fuel into the engine cylinders for combustion. Example: Case IH Puma 240 Fuel Injector - 凯斯 Puma 240 燃油喷射器 - Форсунка Case IH Puma 240.
EGR Valve (Automotive): Recirculates a portion of the exhaust gas to the engine's cylinders to reduce nitrogen oxide emissions. Example: Ford Focus 1.8L EGR Valve - 福特 福克斯 1.8L EGR 阀 - Клапан EGR Ford Focus 1.8L.
Torque Converter (Engineering Machinery): Transfers engine power to the transmission in automatic systems. Example: Volvo L120F Torque Converter - 沃尔沃 L120F 变矩器 - Гидротрансформатор Volvo L120F.
Air Dryer (Heavy Truck): Removes moisture and contaminants from the air system to protect components. Example: MAN TGS Air Dryer - 曼恩 TGS 空气干燥器 - Осушитель воздуха MAN TGS.

Machinery Fault & Solution Example:
Equipment: Caterpillar 345D Excavator
Fault: Sudden loss of hydraulic power and erratic implement movement.
Diagnosis & Solution: One common cause is a malfunction of the Main Relief Valve (MRV) or a compromised hydraulic pressure switch (similar to the 239-3478 but specific to the hydraulic system) leading to incorrect pressure readings to the main pump controller. Solution: Check the diagnostic codes via the monitor. If a pressure sensor fault is indicated, test the sensor with a multimeter and replace it if out of specification. If the MRV is suspected, check for debris or sticking and consider replacement to restore proper system pressure and function. Always use correct hydraulic fluid and filters.
