Repair damaged spark plug threads


Spark plugs can be difficult to remove but they can also be difficult to fit correctly, sometimes resulting in crossed threads or damaged threads. Laser Tools have introduced a spark plug thread chaser (part number 7831) designed to speed things up.

If you feel the spark plug is reluctant to screw in cleanly, the thread chaser can help, for 14mm x 1.25 plug threads, 70mm in length and is 3/8″ drive. Its narrow profile makes it ideal for hard to reach areas.

Coat with grease to catch any metal swarf, then gently run the chaser down the length of the plug thread. It will restore the threads and let you fit the new spark plug.
