The original cover plate part number 4426353 is a protective or sealed cover plate provided by Hitachi Construction Machinery for the ZX200 series hydraulic excavator (with a total working weight of 19.4-20.3 tons and a standard bucket capacity of 0.8-0.91m ³). This cover plate may be used for parts such as fuel tanks, hydraulic tanks, engine hoods, travel motor covers, or side doors. Its universal models usually cover models in the ZX200-3, ZX200-3G, ZX200-5G series, as well as similar tonnage excavators such as ZX210 and ZX240. As original sheet metal or injection molded parts, it is strictly prohibited to use non-standard auxiliary parts that match the depth of the vehicle structure to ensure protection strength and sealing reliability.

Inspection cycle: It is recommended to check the fixing bolts of the cover plate for looseness and the sealing strip for aging and cracking every 250 working hours; Check the flexibility of hinges or buckles every 500 working hours. Installation points: 1 Clean the installation surface (remove oil stains and rust); 2. Align the installation holes (to avoid deformation caused by forced tapping); 3. Tighten the bolts evenly in a cross order (usually with a torque of 20-40N · m); 4. Check the compression of the sealing strip (should be ≥ 30%). Fault diagnosis: If there is abnormal noise, oil leakage, or dust ingress, it is necessary to check whether the cover plate is deformed, the seal is ineffective, or the fixing parts are loose; If the plastic cover plate becomes brittle and cracks, it indicates UV or chemical corrosion aging and should be replaced immediately. Preventive maintenance: It is recommended to replace all sealing strips every 2000 working hours; Regularly clean the surface of the cover plate to prevent dust and corrosive substances from adhering. Safety regulations: Before operation, the negative terminal of the battery must be disconnected and carried out in a stable supporting environment; Dispose of discarded cover plates according to metal/plastic recycling standards. Always use genuine original parts and operate according to the maintenance manual to ensure long-term safe operation of the equipment.
