Glossary of Machinery Parts
风扇马达 (Fēngshàn Mǎdá) / Fan Motor / Вентиляторный двигатель
The fan motor is responsible for driving the cooling fan, which helps regulate the engine temperature. It is typically located near the radiator. Example: Caterpillar 345D Fan Motor (卡特彼勒 345D 风扇马达, Катерпиллер 345D вентиляторный двигатель).
液压泵 (Yèyā Bèng) / Hydraulic Pump / Гидравлический насос
The hydraulic pump converts mechanical power into hydraulic power, which is used to operate various hydraulic cylinders and motors in heavy machinery. Example: Komatsu PC200-7 Hydraulic Pump (小松 PC200-7 液压泵, Комацу PC200-7 гидравлический насос).
主轴承 (Zhǔ Zhóuchéng) / Main Bearing / Коренной подшипник
Main bearings support the crankshaft in the engine block, allowing the crankshaft to rotate smoothly. Example: Cummins N14 Main Bearing (康明斯 N14 主轴承, Камминз N14 коренной подшипник).
连杆 (Lián Gǎn) / Connecting Rod / Шатун
The connecting rod connects the piston to the crankshaft, transmitting the force from the piston to the crankshaft, which in turn rotates the engine. Example: John Deere 6430 Connecting Rod (约翰迪尔 6430 连杆, Джон Дир 6430 шатун).
喷油嘴 (Pēnyóuzuǐ) / Fuel Injector Nozzle / Форсунка
The fuel injector nozzle sprays fuel into the engine's combustion chamber at the precise time and pressure required for efficient combustion. Example: Bosch Fuel Injector Nozzle for Mercedes-Benz Actros (博世 奔驰Actros喷油嘴, Бош форсунка для Мерседес-Бенц Актрос).
空气滤清器 (Kōngqì Lǜqīngqì) / Air Filter / Воздушный фильтр
The air filter cleans the air entering the engine, preventing dust and debris from causing damage. Example: Fleetguard Air Filter for CAT 320D (弗列加 卡特320D空气滤清器, Флитгард воздушный фильтр для CAT 320D).
油门拉线 (Yóumén Lāxiàn) / Throttle Cable / Трос газа

Frequently Asked Questions
Where can I find the part number for my Komatsu equipment?
The part number is usually stamped or printed on the part itself. You can also find it in your Komatsu equipment's service manual or parts catalog.
What is the difference between OEM and aftermarket parts?
OEM (Original Equipment Manufacturer) parts are made by the same manufacturer that made the original equipment. Aftermarket parts are made by other manufacturers and can sometimes be more cost-effective.
How do I know if a part is compatible with my machine?
The best way to ensure compatibility is to match the part number with the one in your equipment's manual or on the original part. You can also consult with a parts specialist.

Troubleshooting Tip
Problem: Excavator Engine Overheating
A common issue in excavators is engine overheating. This can be caused by several factors, including a low coolant level, a faulty thermostat, a clogged radiator, a malfunctioning water pump, or a broken fan belt.
Solution: First, check the coolant level and top it up if necessary. Inspect the radiator for any blockages and clean it thoroughly. Ensure the fan belt is in good condition and properly tensioned. If these steps don't resolve the issue, the thermostat or water pump might be faulty and require replacement. It's recommended to consult a qualified mechanic for a thorough diagnosis and repair.
