Disassembling the key components of the excavator's travel system is a highly technical job, involving many steps and precautions. The following is a detailed process and operating precautions for this part of the disassembly:

1. Preparation
First, make sure that the working environment is clean, tidy, and has sufficient space for disassembly operations. You need to prepare the corresponding tools, including jacks, crowbars, pneumatic wrenches, wrenches, chain removal tools, etc. At the same time, wear necessary personal protective equipment, such as hard hats, work gloves, and protective glasses.

2. Ensure that the equipment is shut down and the power is turned off
Before starting disassembly, make sure that the excavator is in a shutdown state. Turn off the engine and cut off the power to avoid accidents during operation. At the same time, lock the excavator's cab and operating system to avoid any accidental start-up.

3. Support and stabilize the equipment
Use a jack to support the body of the excavator to ensure that the equipment does not tilt or slide during disassembly. The support point should be selected in a stable structural position to avoid damage to the equipment. At the same time, place a safety bracket under the body to increase stability.

4. Loosen and remove the travel part connectors
Loosen the fixed connectors by using a pneumatic wrench or a manual wrench. First remove the pins or bolts that are stuck to the parts, which are usually fixed at the joints of the travel system. Depending on the model of the excavator, the type and number of connectors may vary, so you need to check the design drawings to ensure that all connectors are loose.

5. Remove the wheel hub and chain
After removing the fixed connectors, you need to remove the wheel hub and its corresponding chain from the vehicle body. Be careful when removing and avoid using too much force to pry it open directly. You can use a crowbar or a special removal tool to separate the wheel hub and chain.

6. Check and remove the chain tensioner
The chain tensioner usually includes a tensioning bolt and a hydraulic tensioner. Before disassembly, you need to loosen the bolts or hydraulic equipment on the tensioner to gradually reduce the tension of the chain. Make sure that the tensioner is completely relaxed before you can continue to disassemble safely.

7. Removing Chain Links and Other Accessories
When removing a chain, first remove the connecting rings or pins using a special tool. These connectors usually use pins to connect the links. After loosening these connectors, the links can be removed one by one. Be careful not to damage any important parts, such as pins, nuts, etc. during the removal process. During the removal, you can check the wear of each part one by one to prepare for subsequent replacement or maintenance.

8. Check and clean
After the removal is completed, check the removed parts to ensure that there are no worn or damaged parts. If necessary, some reusable parts can be cleaned, lubricated or repaired. At the same time, you can also check the surrounding environment to ensure that no debris or dirt has entered the equipment.

9. Preparation for reinstallation
During the disassembly process, if you find that there are parts that need to be replaced, you should prepare replacement parts as soon as possible. When removing and replacing new parts, you should follow the manuals and instructions of the equipment manufacturer to ensure that all parts can be installed and tightened correctly. Check the compatibility of the new parts with the original parts to ensure that they can fit perfectly.

10. Safety precautions
During the disassembly process, the operator must be careful and cautious. Since disassembly involves greater mechanical force and weight, it is important to follow safe operating procedures during disassembly. If you are unsure of the operating steps, it is best to seek help from a professional. In addition, the operator should avoid using inappropriate tools or excessive force during the disassembly process to prevent damage to other parts or accidents.

11. Complete disassembly and test
After the disassembly is completed, recheck all removed parts and tools to ensure that nothing is missing. Then, the necessary equipment tests can be performed to check whether the disassembly and replacement process went smoothly and to ensure that there are no abnormalities.

Summary
Disassembling the excavator travel system requires very careful and professional operations to ensure that all work can be completed safely and efficiently. Each step needs to be carried out strictly in accordance with the operating procedures, especially when loosening the connectors, removing the tensioning device, and removing the chain links, a high degree of concentration must be maintained. In addition, as a maintainer or operator of professional equipment, in addition to having certain mechanical knowledge, you should also have the corresponding experience and skills to cope with the disassembly needs of different models of equipment.
