An excavator track adjuster assembly, also known as a track tensioner assembly, is a component of an excavator's undercarriage system. It is responsible for adjusting and maintaining the tension in the tracks (crawler tracks or rubber tracks) of the excavator.
The track adjuster assembly typically consists of several components, including:
1. Recoil Cylinder: The recoil cylinder is a hydraulic cylinder that is connected to the track frame and acts in conjunction with the recoil spring. It provides the force necessary to adjust the tension in the tracks. By extending or retracting the cylinder, the tension in the tracks can be increased or decreased accordingly.
2. Track Adjuster Spring: The track adjuster assembly includes a coil spring, commonly referred to as the recoil spring or tension spring. It works in combination with the recoil cylinder to absorb and distribute forces, maintaining the proper tension in the tracks.
3. Adjuster Piston: The adjuster piston is part of the recoil cylinder and moves within it, responding to changes in hydraulic pressure. As hydraulic fluid is supplied or released into the recoil cylinder, the adjuster piston extends or retracts, adjusting the tension in the tracks.
4. Grease Valve: The track adjuster assembly may also include a grease valve or grease fitting. This allows for periodic lubrication of the assembly to ensure smooth operation and prevent premature wear.
The track adjuster assembly is vital for maintaining proper track tension, which is crucial for the excavator's stability, traction, and overall performance. It helps to minimize track sagging, excessive wear on undercarriage components, and track derailment.
Regular inspection and maintenance of the track adjuster assembly are important to ensure optimal performance and longevity. This includes checking for leaks, proper tension, and any signs of wear or damage. If any issues are detected, it is recommended to consult with the excavator manufacturer, authorized dealers, or qualified technicians for appropriate repairs or replacements.
Price ranges of components of excavator track adjuster assy
1. Recoil Cylinder: $500 to $2,000
- The pricing of recoil cylinders can vary based on the excavator model, size, and brand. Larger excavators or those with higher torque requirements may have more expensive recoil cylinders.
2. Track Adjuster Spring: $100 to $500
- The pricing of track adjuster springs can vary depending on the size and specifications of the excavator. Heavy-duty or specialized excavators may have higher-priced track adjuster springs.
3. Adjuster Piston: $200 to $800
- The pricing of adjuster pistons can vary based on the excavator model and brand. It can also depend on the specific design and materials used in the piston.
4. Grease Valve: $50 to $200
- Grease valves are generally more affordable compared to other components. The pricing can vary based on the quality, brand, and specifications of the valve.
These price ranges are provided as general estimates and should be used as a reference point. The actual prices can vary significantly based on various factors mentioned earlier. To get accurate pricing information for specific components of the track adjuster assembly, it is advisable to contact manufacturers, authorized dealers, or excavator parts suppliers who can provide you with detailed and up-to-date pricing based on your specific requirements and the current market conditions.
