FAQs

What is the primary use of this kit?

This kit is designed for repairing damaged M12 x 1.25 (with M14 x 1.25 outer thread) glow plug threads in diesel engine cylinder heads.

What tools are included in the kit?

The kit includes a reamer, taps, assembly tools, and threaded sleeves of various lengths (12mm, 19mm, and 26mm).

What materials are the threaded sleeves made of?

The product description does not specify the material of the threaded sleeves.

Is this kit suitable for DIY mechanics?

Yes, but some mechanical experience is recommended to ensure correct usage.

What happens if the original thread is severely damaged?

If the damage is severe, use the reamer to re-ream the damaged threads. Then use a suitable tap to cut a new thread to accommodate the tapped bush.

How do I store the kit?

Store the kit in the provided metal tin to protect the tools and prevent loss of parts.

What thread sizes are supported?

The kit supports M12 x 1.25 glow plug threads (with outer thread M14 x 1.25).

Troubleshooting

Thread insert does not seat properly.

Ensure the original thread is properly reamed and the new thread is tapped correctly. Check for debris and ensure the insert is aligned before installation.

Difficulty inserting the threaded sleeve.

Make sure the correct assembly tool is used. Apply gentle, even pressure and ensure the sleeve is not cross-threaded.

The glow plug does not fit after repair.

Double-check the thread size (M12 x 1.25) and ensure no debris is blocking the thread. If the glow plug still doesn't fit, re-tap the thread.
