2055345 Original Loader Shim for ZW220  

Hitachi original loader gasket (universal part number: 2055345) is a genuine seal provided by Hitachi Construction Machinery. As an original spare part, it is specially designed for Hitachi brand loaders to ensure perfect matching with various connection parts of the equipment. This gasket is widely compatible with multiple mainstream wheel loader models from Hitachi, including the ZW series (such as ZW140, ZW180, ZW220, ZW250, ZW310, ZW330, etc.) and some models from the LX series. Gaskets are commonly used for planar sealing of critical components such as engines, transmissions, and hydraulic systems.
 

This gasket is a key component of the loader sealing system, whose core function is to form a reliable seal between two connecting surfaces, preventing leakage of lubricating oil, hydraulic oil, coolant, or gas. As an original component, it is made of high-quality materials such as oil and high temperature resistant synthetic rubber (such as nitrile rubber), flexible graphite, or metal composite materials, which can withstand the pressure, temperature, and vibration during equipment operation. The gasket has precise thickness and size, with a flat and uniform surface, ensuring effective filling of micro unevenness under bolt tightening pressure and achieving long-term sealing. Its design strictly follows the original factory standards, with excellent resistance to compression permanent deformation and chemical stability. It can work for a long time in a wide temperature range of -40 ° C to 150 ° C and oil contaminated environments, ensuring that all systems of the equipment operate without leaks and stably.
 

To ensure the long-term effective sealing effect of the gasket, it is necessary to follow the standardized installation and maintenance procedures. Before installation, the connection surface must be thoroughly cleaned to ensure that there are no old gasket residues, oil stains, rust or scratches. Check if the gasket itself is intact, without creases or deformations. During installation, it is necessary to cross tighten the bolts according to the torque and sequence specified by the original factory to ensure even pressure distribution. Regularly (recommended every 1000 working hours or in conjunction with regular maintenance) check for any signs of leakage at each sealing point. If a leak is found, the gasket should be checked and replaced in a timely manner. Gaskets are disposable consumables and must be replaced with new ones after disassembly. They cannot be reused.
