This kit is designed for repairing damaged M12 × 1.25 glow plug mounting threads in the cylinder head.

Slightly damaged original threads can be restored using the included thread chaser.

If the original thread is severely damaged, the bore can be reamed and tapped to accommodate one of the supplied thread inserts.

Instructions for Use

For Slightly Damaged Threads

Re-cut and restore the original M12 × 1.25 thread using the appropriate thread chaser.

For Severely Damaged Threads

Ream out the damaged original thread using the supplied reamer.
Use the appropriate tap to create a new M14 × 1.25 internal thread for the thread insert.
Slide the installation sleeve onto the corresponding installation bolt and screw on a thread insert of the required length.
Use the installation tool to screw the thread insert into the newly cut internal thread and tighten it lightly.
Remove the installation bolt and sleeve.

Important Note

We recommend securing the thread insert in the newly cut internal thread with a suitable thread-locking compound. This helps prevent the insert from unscrewing when the glow plug is removed later.
