OEM HITACHI EX100 120-5 TRACK ADJUSTER CYLINDER (OEM HI 3073803) | Tonkee®

Function: The primary function of the track adjuster cylinder is to control the tension of the tracks.

It allows for the adjustment of the track's sag or tension, depending on the operating conditions and terrain. Proper track tension is essential for efficient operation and minimizing wear and tear.

Material: The cylinder is typically made from high-strength steel or alloy materials to withstand the high loads and pressures encountered during excavator operation. These materials provide durability and resistance to corrosion.

Hydraulic Operation: The track adjuster cylinder is a hydraulic component, meaning it operates using hydraulic fluid under pressure. It connects to the excavator's hydraulic system, allowing for precise adjustment of track tension.

Piston and Rod: Inside the cylinder, there is a piston connected to a rod. When hydraulic pressure is applied to one side of the piston, it extends or retracts the rod, thus adjusting the tension of the tracks.

Seals: To prevent hydraulic fluid leaks and contamination, the cylinder is equipped with high-quality seals.

These seals ensure that the hydraulic pressure is maintained, and no dirt or debris enters the system.

Size and Dimensions: The exact size and dimensions of the track adjuster cylinder may vary depending on the specific model and year of manufacture of the Hitachi EX100-5. It is designed to fit seamlessly within the excavator's undercarriage.

Installation: The track adjuster cylinder is typically installed in the undercarriage of the excavator, where it connects to the track frame and idler wheel assembly. Proper installation is crucial to ensure optimal track tension and performance.

Maintenance: Regular maintenance of the track adjuster cylinder is essential to ensure its continued functionality. This includes inspecting for leaks, checking hydraulic connections, and lubricating moving parts.

Replacement: If the track adjuster cylinder becomes damaged or worn beyond repair, it should be replaced with a genuine OEM part like the HI 3073803 to maintain the excavator's performance and safety.

Compatibility: It's essential to ensure that the replacement cylinder is compatible with the specific model and configuration of the Hitachi EX100-5 or EX120-5 excavator.
