Firstly, regarding thread protection
1. Rust prevention treatment: Apply rust inhibitor to the threads before disassembly to reduce disassembly resistance and prevent rusting.
2. Rotation direction: Strictly follow the principle of "loose on the left and tight on the right", rotate counterclockwise to remove the threaded component.
3. Auxiliary tool: Use thread protection sleeves or tape to wrap exposed threads to avoid collision during transportation.
Secondly, seal replacement
1. Old part cleaning: Use a non-metallic scraper or solvent to thoroughly remove residual sealant or impurities from the sealing groove.
2. Installation technique: Apply lubricating grease (such as lithium based grease) on the surface of the seal, use specialized installation tools to evenly press it in, and avoid twisting or shearing.
