Head Stud Repair Repair
Posted by: Ian Harding ()
Date: February 27, 2007 09:10PM

I got my Time Sert repair kit, new stud, ready to go fix the stud that pulled out.

Well, what pulled out was a Heli Coil repair, leaving me with a hole as big as my thumb.

Is there any such thing as an extra thick insert for this problem, or does it need to be welded up and re-drilled?

Thanks,

Ian

One option: If you have enough room(block material where the Helicoil came out),have a machine shop make a custom threaded insert,thread the block and install with Loc-Tite.

Yeah, I think that might work. There seems to be plenty of metal left around the hole.

Thanks!

Really? I didn't think it would hold up. Has anyone used it for a head stud thread repair?

Thanks!

doubt it would hold up either, I thought timeserts were larger on the outer diameter anyway, can't you use it as is?

Timesert also makes a Bigsert just for this type of repair. Clarks has them listed in their catalog.

Nope. The Helicoil yanked out a ton of aluminum. 8^(

It literally slips right in.

Figures! I wonder if they will give me a break for being a dummy and not make me pay 2 tool rentals.

Take it from me JB weld wont hold up. I tried with one of my blocks to use it and it just pulled right out. Now that block is laying on floor of my barn. Good luck Steve.

Here's one quick way to fix a very over-size stud hole, and it will last. Determine what size "pipe thread" tap will rethread the hole(usually 1/4 or 1/2')and if there is room and access to do the repair. Get a square headed pipe plug that is solid,(some are half hollow). Tap the hole in stages and test fit the plug as you go untill,when it's screwed in tight, it will be flush with the block after you cut the square head off. Then center-punch,drill and tap for the stud, Install with JB-Quick on both threads. I have done this many times,one was even 3/4' pipe, and most were done in the car.
