- This is a tut on how to repair striped threads with a heli-coil thread repair kit. The example that i'm using here is a brake caliper slide bolt on a 1997 Dodge dakota. The process is pretty much the same for any thread repair.
Questions welcome! Tut requests welcome

I've gotta say yours is the best video on this specific subject I've watched. I certainly know how to drill out, and tap a hole. However your step by step instructions were very informative and made me feel much more confident in completing this task. Thank you
Unlike our mech here, Don't ever pull the drill in and out. Every time you do you're rattling the drill in the new hole that you want to be as tight as possible. And NEVER do the in and out routine on your final diameter drill size.
Running the drill in and out after the first pass only enlarges and misshapes the hole when you need every grain of thickness to remain for your new Helicoil thread to bite into.
NEVEN NEVER ream the drill in and out. One straight pass is all you get. Protect the remaining metal. You need it in the hole. Not on the floor. Especially if you're short of wall thickness like this job.
Otherwise, all good.
What a fantastic video... Thanks alot. I'm doing this tomorrow, then the day after we're going on the ferry from Genoa to Sicily!!! Huge stress but you've just relived alot of it thanks buddy!! Just hope my small drill can do it
Before you buy make sure you have enough metal left. Had a 2000 Durango were this fix would have opened up hole and had only paper thin metal on outside diameter. Great fix, good video!
Damn, really? The 2000 Durango is so close in build to this 97 Dakota, or my 98 Dakota. I better go out and check that I can put a 3/8" hole in there B4 I continue down this path.
Great video thanks for the info helped a ton!!
You forgot to tell them to knock the tab of the off of the coil
You're right, but it's a good video overall, and if anybody were to watch a few of these videos for this task they're gonna figure it out.
@@BengtRosini13 I need to do mine on my car.
Great video thanks
It is called a heli-coil. And Oreillys auto parts sells them or any hardware store should have them! Hope this helps :)
Shouldn't you back up a quarter turn or so for every 3/4 to 1 full turn in ? When tapping/cutting the new threads for the helicopter coil
If you tap the hole, let's say previous size was 7mm, the new tapped hole is 8mm, would it make sense to use a 8mm slide pin and not use the helicoil.
I need to do this to my Ford Focus SE, I have a stripped spindle hole, how would you rate this job, I never done this before but I am about to do this, 1 being easy, 10 being very difficult.
Would it be better to use 3/8 drill bit or 23/64? A lot of videos/forums suggest you should use 23/64. I just ordered the Helicoil kit so I wanna be sure.
Yep
Where can I find that repair kit? Is it metric or SAE?
