Thread Repair
 

I can not be the only one won needs to repair the threads on the glow plug hole in the head.
Is there a good way to repair the threads in the head?
I know you can re-tap them, but can you replace them?
Is there an insert on the market to fix them?

Please let me know if anybody does.

Thank you

Todd,


Welcome to RCU.

You can do a search about this subject within the Glow Engines forum.

It has been discussed several times lately.


A Heli-Coil will solve your problem, but the kit (for 10 repairs) is very expensive.
You need the 1/4-32 thread, which is rare UNEF. Another thread will not work!

Or if your engine is made by a 'normal' company (not OS, TT, Etc.) buying a new head will probably cost less...


Edit: Clarence Lee of RCM offers thread repair for a competitive price.

I think Mr Lee charges a whopping $14.50 to do the job. Just send him the head in a suitable envelop with a check or money order and he will have it back to you in a week or 10 days. See his ad in AMA magazine in the classified section.
