How to quickly disassemble an assembled rubber joint.
Using the leverage principle method of disassembly: using a pry bar to deduct a small pocket at the edge of the rubber part of the joint, and then deducting a small pocket every other size to pry open the flange in turn, this method is relatively simple and easy to find using tools, but the disadvantage is that it depends entirely on your own strength, and there are operational risks and easy to scratch the joint.
Disassembly according to the installation method of the joint: i.e., the ball and flange are semi-separated by rotating the joint, and then completely separated by external force.
This method is recommended for experienced people. Disassembly by machinery: Using the strong stretching effect of the machine, the joint flange is pulled off.
