OEM HITACHI ZX160 HYDRAULIC PUMP OIL SEAL 42 X 65 X 12 MM (OEM HI 4340358) | Tonkee®

The Hitachi ZX160 hydraulic pump oil seal has specific dimensions of 42 x 65 x 12 millimeters (mm).

These dimensions are critical to ensure a proper fit and seal within the hydraulic pump assembly. The 42 mm inner diameter, 65 mm outer diameter, and 12 mm thickness are designed to match the pump's internal components precisely.

Material Composition:

The oil seal is typically composed of high-quality materials to withstand the demanding conditions within the hydraulic system. These materials are chosen for their resistance to hydraulic fluid, temperature extremes, and wear and tear. The specific composition may vary depending on the manufacturer, but commonly used materials include rubber or elastomers for the sealing lip and a metal or reinforced core for stability and durability.

Function and Importance:

The primary function of the oil seal is to prevent hydraulic fluid from escaping the hydraulic pump. Hydraulic pumps generate high-pressure fluid flow that powers various functions of the excavator, such as the movement of the boom, arm, and bucket. Any leakage in the hydraulic system can result in reduced efficiency, loss of hydraulic power, and potential damage to other components.

By maintaining a tight seal, the oil seal ensures that hydraulic fluid remains within the system, enabling smooth and reliable operation of the excavator.

This not only enhances performance but also extends the lifespan of the hydraulic components.

OEM Part Number (HI 4340358):

The oil seal carries the OEM part number HI 4340358, which indicates that it is manufactured by Hitachi itself or by a trusted supplier authorized by Hitachi. Using OEM parts is essential for ensuring compatibility and maintaining the excavator's warranty. It also ensures that the oil seal meets Hitachi's quality and performance standards.

Compatibility:

The Hitachi ZX160 hydraulic pump oil seal is specifically designed for use in the ZX160 excavator model. It is crucial to verify compatibility before installation to prevent any issues or damage to the hydraulic system. Using the correct oil seal ensures a proper fit and reliable sealing performance.
