Buy HITACHI EX100 120-1 TRACK ADJUSTER CYLINDER (OEM HI 3034933) | Tonkee®

The track adjuster cylinder is a hydraulic component designed to adjust the tension of the tracks on the excavator.

It is an essential part of the undercarriage system, as it allows the operator to control the track tension, which, in turn, affects the machine's stability, traction, and overall performance. The cylinder is part of a system that includes a hydraulic piston and a nitrogen-filled accumulator.

Materials and Construction:

The Hitachi EX100-1 and EX120-1 Track Adjuster Cylinder is manufactured using high-quality materials to withstand the demanding conditions of construction and excavation work. The cylinder body is typically made from durable steel to ensure long-lasting performance in harsh environments. The piston rod is also constructed from strong materials, often featuring a chrome plating to resist corrosion and wear.

Dimensions:

The specific dimensions of the cylinder may vary slightly depending on the manufacturer, but generally, it is designed to fit the EX100-1 and EX120-1 excavator models. Typical specifications for the cylinder include a length of around 800-900 millimeters, a diameter of approximately 90-100 millimeters, and a stroke length of 500-600 millimeters. These dimensions ensure compatibility and proper function with the excavator's undercarriage system.

Hydraulic System:

The track adjuster cylinder operates within a hydraulic system.

It is connected to the excavator's hydraulic lines, allowing for the precise adjustment of track tension. When the operator engages the adjustment mechanism, hydraulic fluid is directed to the cylinder, causing the piston to move. This movement either increases or decreases the tension in the tracks, depending on the operator's requirements.

Nitrogen Accumulator:

In addition to the hydraulic components, the track adjuster cylinder also includes a nitrogen-filled accumulator. This accumulator stores energy in the form of compressed nitrogen gas. When the cylinder extends or retracts, the accumulator helps maintain consistent tension in the tracks by absorbing shocks and fluctuations in hydraulic pressure. This feature is crucial for ensuring a smooth and stable ride for the excavator, even in rough terrain.

Maintenance and Service:

Proper maintenance of the track adjuster cylinder is essential to ensure its longevity and performance. Regular inspections, lubrication of moving parts, and the replacement of seals and gaskets as needed are part of routine maintenance. Additionally, it's crucial to monitor the nitrogen gas pressure in the accumulator to ensure it remains within the recommended range.
