YA00083426 Excavator Seal Kit for ZW310-5A

Part number YA00083426 is the original sealing kit provided by Hitachi for the ZW310-5A wheel loader. According to trade data, this part number corresponds specifically to Hitachi sealing kits used for equipment such as excavators and mining trucks. As a complete sealing solution, its universal model may cover other similar models in the ZW310 series (such as ZW310-5, etc.)

This product is a complete set of sealing components, usually including O-rings, oil seals (such as YA type universal shaft seals), gaskets, piston seals and other key components. Its main function is to establish reliable seals in the hydraulic system, lubrication system, and various connecting parts, prevent leakage of working media (hydraulic oil, engine oil), and block the invasion of external pollutants such as dust and moisture, ensuring the cleanliness and efficient operation of the system. Modern construction machinery has extremely high requirements for sealing, and the sealing components in such kits often use high-performance elastic materials, such as oil resistant and wear-resistant nitrile rubber (NBR), polyurethane (TPU/CPU), etc. These materials have excellent physical and chemical properties: the working pressure can usually reach 32MPa or even higher, and the working temperature range covers -40 ° C to+120 ° C, which can adapt to the operating needs of equipment in various harsh conditions. The components in the kit are designed with precision, and their dimensions match perfectly with the original equipment parts. They are essential consumables for major repairs or preventive maintenance of hydraulic cylinders, valve groups, pumps, pipeline joints, and other parts.

Replacement cycle: Seals are vulnerable parts, and their lifespan is greatly affected by working pressure, temperature, medium cleanliness, and equipment load. It is recommended to conduct a comprehensive inspection every 3000-5000 working hours or every 2 years. Once any oil stains, leaks, aging or cracking of seals are found, they should be replaced immediately. For equipment with high work intensity and harsh environment, the inspection cycle should be appropriately shortened.
