How to Remove a Broken Spark Plug?
1 Answers
There are several methods to handle a broken spark plug: 1. Welding Method: This approach usually requires multiple welding attempts to succeed and is relatively difficult. 2. Reverse Thread Tool: Special reverse thread tools for removing broken spark plugs are widely available. Use the reverse thread tool to tap threads inside the spark plug head. During the tapping process, fine metal shavings may fall into the cylinder, which can be cleaned up using a magnetic rod. 3. Forceful Hammering: This method not only damages the threads on the cylinder but also fails to completely remove the fragments, potentially harming the engine. Therefore, this method is not recommended.
