First. The common tool method. For general parts disassembly, such as lubricated and rusted fasteners, can be removed using common tools; for special (specified torque) fasteners, torque wrenches and sleeve wrenches can be used for removal. In case of bolting or nut working face chamfering, it can be twisted by hammer and then twisted; when the bolt gap of the screwdriver working face slips, the saw bow can be dismantled according to a gap along the vertical position.

Second. The tapping method. For parts that have been rusted due to long-term static cooperation, such as universal joint cross shafts, steering rockers, and various types of bearings, tapping can be used. This method is widely used, and its function is to destroy the rust bond between the parts, causing them to vibrate and disengage. When knocking, it is necessary to correctly select the parts to prevent the parts from being damaged, especially for parts with high precision requirements, such as the disassembly of various types of bearings. In order to prevent the working surface from being damaged, apply a soft cloth pad and tap with a hammer. can.

Third. Heating oil leakage method. Parts that are severely difficult to disassemble. Such as leaf spring riding bolts, knuckle arm nuts, etc., due to long-term maintenance, corrosion is serious, this can be added to the oil, so that it can be lubricated after thermal expansion, you can unscrew. When heating, pay attention to whether there are flammable materials such as oil and rubber around the parts to prevent fire.
