格莳国际 (英文名：Growshine International) 是一家专业的进出口贸易公司，主营 工程机械配件、重卡配件、农机配件 和 汽车配件。我们致力于为全球客户提供优质可靠的零部件产品和服务。
以下是一些与工程机械、重卡、农机和汽车相关的配件名词解释：
空气滤清器 (Air Filter)：安装在发动机进气系统中的部件，用于过滤进入发动机的空气中的灰尘和杂质。例如：卡特彼勒 320D 空气滤清器 (Caterpillar 320D Air Filter) (空气ный фильтр).
液压油缸 (Hydraulic Cylinder)：工程机械中执行机构，将液压能转化为机械能，实现各种动作。例如：小松 PC200 液压油缸 (Komatsu PC200 Hydraulic Cylinder) (гидравлический цилиндр).
喷油嘴 (Fuel Injector)：重型卡车发动机的关键部件，负责将燃油以雾状喷入燃烧室。例如：斯堪尼亚 R500 喷油嘴 (Scania R500 Fuel Injector) (топливная форсунка).
离合器片 (Clutch Disc)：重卡变速箱中的重要部件，用于传递发动机动力和分离动力。例如：奔驰 Actros 离合器片 (Mercedes-Benz Actros Clutch Disc) (диск сцепления).
犁铧 (Plowshare)：农用机械中用于翻耕土壤的部件，安装在犁上。例如：约翰迪尔 8R 犁铧 (John Deere 8R Plowshare) (лемех).
收割机刀片 (Harvester Blade)：农业收割机上用于切割农作物的部件。例如：克拉斯 Lexion 收割机刀片 (Claas Lexion Harvester Blade) (нож комбайна).
火花塞 (Spark Plug)：汽车发动机点火系统的重要组成部分，用于点燃混合气。例如：丰田凯美瑞火花塞 (Toyota Camry Spark Plug) (свеча зажигания).
刹车片 (Brake Pad)：汽车制动系统中的摩擦部件，通过与刹车盘摩擦产生制动力。例如：宝马 5系刹车片 (BMW 5 Series Brake Pad) (тормозная колодка).
轮胎 (Tire)：各种车辆的重要组成部分，支撑车身并与地面接触。例如：米其林卡车轮胎 (Michelin Truck Tire) (шина).
发电机 (Alternator)：汽车和工程机械等设备的电力供应系统中的关键部件，用于产生电能。例如：日立挖掘机发电机 (Hitachi Excavator Alternator) (генератор переменного тока).
定期更换机油：确保发动机内部润滑，减少零件磨损，延长发动机寿命。
检查冷却液液位：防止发动机过热，保持发动机在正常工作温度范围内。
定期检查和更换空气滤清器：保证发动机吸入清洁的空气，提高燃烧效率。
详细描述：当您转动钥匙启动发动机时，听到启动马达发出咔哒声或者没有反应，这可能是电磁开关出现故障。电磁开关的作用是接通启动马达的电源，如果其内部触点损坏或线圈故障，将无法正常工作。
处理方案：
检查电源连接：首先检查电池连接是否牢固，电缆有无腐蚀或松动。
检查保险丝：检查启动系统的保险丝是否熔断，如有熔断进行更换。
测试电磁开关：可以使用万用表测试电磁开关的输入和输出电压，判断其是否正常工作。
更换电磁开关：如果确认电磁开关损坏，需要及时更换新的电磁开关。请务必选择与原型号匹配的 卡特彼勒 3E-5370 或 3E5370 电磁开关。

As a leading exporter in the China market, Growshine International specializes in providing high-quality, reliable, and cost-effective alternatives for a wide array of original equipment manufacturer (OEM) parts. We focus on engineering machinery parts , heavy truck parts , agricultural machinery parts , and automotive parts import and export trade. Our extensive inventory covers essential components for popular brands like Komatsu , Caterpillar , and Cummins , ensuring your equipment gets back to work fast.
Searching for specific Komatsu PC300-7 parts or Komatsu PC300-8 components ? Our listings include everything from seals and filters to complex valve assemblies and track parts. We offer exceptional value on high-wear items like PC300-6 Bucket Teeth (part number 207-70-14151) and specialized Hydraulic Breaker components, making us the go-to source for international buyers looking for reliable China alternative parts .
Maintenance is key to maximizing uptime. We stock a full range of filtration products, including the PC300-7 Fuel Filter (part number 600-311-9121) and PC300-6 Diesel Filter (part number 600-311-8321). For Komatsu WA380-3 , the Oil Water Separator (part number 22U-04-21131) is crucial for engine longevity. Structural and hydraulic integrity is maintained with parts like the PC300-8 Retainer Guide Plate (part number 708-2G-13341) and various high-pressure Hose Assemblies like 207-62-71740 for the Komatsu PC300-8.
Our commitment to quality ensures that every product, from a simple PC300-7 O-Ring (part number 07000-B2012) to a complex PC300-7 Valve Assembly (part number 20Y-60-311131), meets stringent performance standards. We help global clients reduce operational costs without sacrificing machine performance, focusing on delivering the best cost-effective spare parts .
One common issue with the Komatsu PC300-8 excavator is a slow or unresponsive boom/stick due to a faulty Solenoid Valve or contamination. If the machine's movement is sluggish, especially after initial startup, first check the Hydraulic Tank Breather Filter (part number 20Y-60-21470 for the D27 -5 series) and the main Hydraulic Oil Filter Element (part number 207-60-71182). A clogged filter can restrict flow. If filtration is clear, inspect the pilot pressure lines and the main control valve's internal components, including the PC300-8 Spring (part number 708-2G-13152) and PC300-8 Slide Block (part number 708-2G-14120). Replacing faulty pilot hoses or the control valve's internal parts often restores full hydraulic responsiveness. Always use correct Komatsu genuine replacement components or tested high-quality aftermarket equivalents.
Beyond standard maintenance, we supply specialized items for various heavy machinery. For hydraulic breakers , we offer parts like the GBF320 Vertical Pin (part number F3201704) and SB121 Check Valve (part number F3205000). For undercarriage maintenance on dozers, we have D27 -5 Final Drive Bolts (part number 09203-12485), D27 -5 Track Assemblies (part number 17M-32-02440), and associated seal kits like the Tension Cylinder Seal (part number 180-30-14220). Furthermore, we can assist you with your requirements for Garrett Turbocharger components and KALMAR parts.
Our inventory also supports other leading equipment. For the Cummins NT855 engine , we provide the correct Seal Ring (part number 409191). For the ZDXLB-DH50/58/8/6.5 Grab Bucket Cylinder Repair Kit for the Janyoung JY640E grab steel machine, we ensure a perfect fit, offering a full range of excavator oil cylinder repair kit options.
