The parts list for an excavator arm can vary depending on the specific make and model of the excavator. However, here is a general list of common components you may find in an excavator arm assembly:
1. Arm Cylinder: The arm cylinder is responsible for extending and retracting the excavator arm. It provides the hydraulic power necessary for arm movement.
2. Arm Boom: The arm boom is the main structural component of the excavator arm. It extends from the base of the machine to the end of the arm.
3. Boom Cylinder: The boom cylinder controls the movement of the boom, allowing it to raise and lower.
4. Arm Linkage: The arm linkage consists of various linkages and joints that connect the boom to the arm. It provides flexibility and articulation for the arm movement.
5. Bucket Linkage: The bucket linkage connects the arm to the bucket. It allows the bucket to tilt and curl for digging and dumping operations.
6. Bucket Cylinder: The bucket cylinder controls the opening and closing of the bucket. It provides the hydraulic force required for bucket operation.
7. Pins and Bushings: Pins and bushings are used to connect the various components of the excavator arm. They provide pivot points and allow for smooth movement.
8. Grease Fittings: Grease fittings are used to lubricate the moving parts of the excavator arm to reduce friction and ensure smooth operation.
9. Wear Plates: Wear plates are installed in areas where there is frequent contact and friction, such as the bucket linkage. They help protect the components from excessive wear and tear.
10. Mounting Brackets: Mounting brackets are used to secure the arm assembly to the excavator's mainframe.
It's important to note that this is a general list, and the specific components and part numbers can vary depending on the excavator model and manufacturer. For accurate and detailed information about the parts list for a specific excavator arm, it is recommended to consult the equipment's service manual or reach out to the manufacturer or authorized dealer for the most up-to-date information.
