3112465 Original Loader Gasket for Hitachi ZW220 

Hitachi original loader gasket (universal part number: 3112465) is a widely used standard sealing and spacing component in the Hitachi loader series. This gasket is mainly suitable for multiple Hitachi wheel loaders, with common models including ZW140, ZW180, ZW220, ZW250, ZW310, ZW330, ZW370-G, ZW550-G, etc. Due to the fact that gaskets are highly versatile parts, the same part number may be used in different models and assemblies (such as engine oil pan, transmission interface, hydraulic valve block, etc.). Before ordering and replacing, it is necessary to verify the specific model, year of manufacture, and accurate installation location of the equipment by referring to the original parts manual or through the electronic parts catalog (EPC) to ensure that the size, material, and thickness are completely matched.
 

As a key sealing and connecting component, this gasket mainly functions to fill the micro unevenness between two connecting surfaces, prevent liquid (such as oil, hydraulic oil, coolant) or gas leakage, and also adjust the gap, prevent loosening and shock absorption, isolate dissimilar metal contacts to prevent electrochemical corrosion. As an original component, it is made of high-quality materials and may be selected from materials such as oil resistant rubber, composite fibers, metal cladding (such as ladle rubber), or pure metal (such as copper, aluminum, stainless steel) depending on the application site.
 

Gaskets are vulnerable parts that are regularly replaced, and their maintenance core lies in preventive replacement and standardized installation. It is recommended that during each engine overhaul, gearbox disassembly, hydraulic system maintenance, or related assembly disassembly, regardless of the appearance of the old gasket, it must be replaced with a new original gasket, and reuse is strictly prohibited. Before installation, both mating surfaces must be thoroughly cleaned to ensure no oil stains, rust, or old sealant residue, and wiped clean with a lint free cloth.
