Spark Plug Thread Repair Set M10 × 1.0, 5 pcs.

This five-piece repair set is designed for restoring damaged M10 × 1.0 spark plug threads.

The supplied M12 × 1.0 HSS tool reams out the damaged original thread while simultaneously cutting a new receiving thread for the repair insert. Four M10 × 1.0 inserts in different lengths allow the appropriate version to be selected according to the depth of the original spark plug thread.

2. Insert the tool into the damaged spark plug thread.
3. Ream out the original thread while simultaneously cutting the new receiving thread for the repair insert.
4. Ensure that no swarf enters the combustion chamber.
5. Screw the selected repair insert onto the spark plug.
6. If required, apply a suitable liquid thread-locking compound to the insert.
7. Use the spark plug to screw the repair insert into the newly cut receiving thread.
