XB00003490 Original Excavator Spacer for ZX135W-7

The original gasket (part number XB00003490) is a genuine sealing component of Hitachi ZX135W-7 wheel excavator, mainly used for the static sealing parts of the engine, hydraulic system or pipeline of this model. ZX135W-7 is a 13.5 ton wheel excavator from Hitachi Construction Machinery, equipped with a diesel engine that meets Stage V emission standards and a HIOS V hydraulic system as standard. The universal number XB00003490 of this gasket is its unique identifier in Hitachi's original accessory system, ensuring complete matching with the size of the host sealing surface, medium compatibility, and operating requirements. When placing an order, it is necessary to provide the complete model and serial number of the excavator for verification to avoid mismatches.

This product is a functional sealing gasket commonly used in construction machinery. It may be made of metal winding (such as 304/316 stainless steel belt+graphite), flexible graphite or oil resistant rubber (such as NBR, FKM), and has excellent oil resistance, high temperature resistance (about ‑ 40 ° C to+200 ° C), pressure resistance, and anti-aging resistance. Its structural design needs to meet the long-term reliable sealing requirements of excavators in vibration, impact, oil immersion, and dusty environments, such as for flange connections, cylinder heads, oil pans, or pipeline joints. The thickness, hardness, compression rate, and rebound rate of the original gasket have undergone strict matching tests to ensure that the sealing integrity can still be maintained under system pressure fluctuations.

It is recommended to check the gasket for signs of hardening, cracking, deformation, crushing, or leakage every 500 hours of work or every quarter. When replacing, thoroughly clean the installation contact surface, remove old pad residue and oil stains, and use original XB00003490 pieces. During installation, the torque and sequence specified in the maintenance manual should be uniformly tightened to avoid twisting or early failure of the gasket due to excessive tightening on one side. Daily storage of gaskets should be kept in a cool and dry environment, avoiding contact with sharp tools, strong solvents, and long-term direct sunlight. Regular maintenance can effectively prevent oil leakage, system contamination, and component wear, ensuring stable operation and service life of equipment.
