In this video I show you how to re thread a stripped bolt hole in a cylinder head on a lawn mower but also can be performed on anything. I demonstrate how to go about getting the correct bolt size and how to pick the kit you need.
Now I mentioned in the video that you should nt use an impact to install bolts, that was wrong. I meant to say is that you should not use impacts to install nuts and bolts on critical things like cylinder heads, intake manifolds, sensors and various soft materials like aluminum and plastic.

I broke the coil while tightening one of the bolt of my new exhaust manifold. Yap the bolt just keeps on turning after that. It was fixed now. I ended up replacing the washer with a thinner one just to chase the remaining coil.

[@lexluthor6314]

It's not worser than a broken bolt

[@alexavila7489]

I feel the pain brother. I popped the threads on my oil cooler for a 17 wrangler

Still don’t be tempted to go ahead and try when u don’t have a clue , I just done to my 250 and I’ve made the threads worse helicoil failed and tool warped , take to pro or you’ll be a lot of money out of pocket

[@sandrarichardson2713]

After watching I can't tell you how many videos for the helicoil installation, you are the first to tell me HOW to find out what size I needed to buy. I am sure there must be another video or two that gives that information but it has been frustrating seeing how to install one but not know how to decide the size to buy. This was really great. Thanks for the help and Jesus bless.

you just saved me a lot of money. Stripped the holes my shock mount bolts on to on my car. Was about to take it somewhere to be professionally repaired, but I found your video and gave it a shot, and it's really quite easy. thanks a lot!

[@jrichie333]

That was a great video. When tapping the bolt hole, I've noticed that the thread chips will break into smaller pieces if you unthread about a quarter turn for every turn that you thread the tap in. It results in a stronger threading and less stress on the cut. Also, you'' be able to tap the hole with less effort

[@handymanPF]

Zer0 Yes you are correct. Thanks for watching and thanks for the comment.

[@ALH-xj1ps]

I've seen other videos on helix coils and the last step was to knock out the small hook on the end of the coil but I didn't see you do this at the end of the installation of the helix coil.

[@butchs2337]

i read many comments on how he should have tapped the hole by turning and then back, he did say it was an alum head which for sure is very soft compared to steel, i myself thought he was going to deep with the new threads, but this video does gives people the idea how to fix a bad hole, heli coil

[@12101DyM]

When tapping it's best to turn forward a full turn then back half a turn to "break the chip" of the threads that you're cutting. By simply running it straight through you put a lot of stress on your tap, and removing a broken tap turns a bad day into a shitty day.

[@stever5887]

Amen to that.

[@labibbidabibbadum]

Nah - that's easy, you just need to get one of those drill bits that can cut a beautifully straight core through a little chunk of hardened steel with a splintered-off top. I forget the brand of those bits, but they're usually on the shelf next to the broken camshaft glue.

[@robertclymer6948]

Absolutely! Good catch! I saw that too.

[@christoph404]

use cutting oil, WD40 spray will do, and each time you make a full turn clockwise do a half turn anti just to break the metal chips, just makes it a bit easier and less chance of error...but you did a good job anyway so I guess you have done it before!!

[@stever5887]

You can use the wrench shown in the video, of course, but you'll have an easier time of it using (1) A 12-point socket and ratchet, (possibly with an extension); (2) The closed end of a combination wrench; OR (3) A die handle from a tap-and-die set. I prefer the latter, but you need lots of space to turn it, which you may not have in constricted areas. However, it provides you a means to evenly distribute the force (think of it as a large T-handle wrench).

[@saknwhyz]

this video gave me Forest whitaker eye. there is some mildly funny stuff like the bit not staying in and for the love of God use oil then follow proper procedure to use the tap. do not run the tap straight through it can cause issues and not cut correctly.

you need to break off the install tab and take it out, also before installing heli coil you put on some red tread locker, otherwise next time you take the bolt out the heli insert will come out with it. I am surprise the little inspector who was watching in the beginning of the video did not say something and let you continue. He shows interest that is good.

You can repair a M6 hole by using a BSF bolt 1/4 inch. It has the same pitch and is slightly bigger. M7 has also the same pitch, but is way thicker.

[@donwest5387]

where do I get English bolts?

[@rvqx]

​​@@donwest5387you ask someone Who has an old,historic english motorbike. Or look for a club english motorbikes and ask. It is very common on a bsa and others.

[@joshward9182]

Nice video. Just a note that on the insert tool has a collar with a grub screw which you can lower to the top of the insert. This acts as a stop so you don't put the insert in any deeper than you need to, which can easily be done. If it is too deep. in some applications, the bolt may only be caught on a couple of threads of the insert, which is not enough. Also, you need to break the tang at the bottom when it's inserted. Just take the tool out slightly, turn 90 degrees, and tap it with a hammer/wrench/heavy-ish object :-)

[@HouseCallAutoRepair]

Nothing like forgetting to break off the tang, and then ripping the helicoil back out with the bolt.... Been there done that. Novice mistake.

[@floridagirl386]

That's what my dad taught me too! I forgot that while rethreading the fuel inlet on my boat carb & bam had to go up the next size...& the metal was so thin @ that point I didn't want to chance it so 400 bucks went down the drain on a new carb lol

[@NicholasMaietta]

Very cool. Thanks for this video. Without this video, i would have probably had to make a second trip for the drill bit, but now I know to open the manual and look for the size drill bit I need. Also, the bolt measuring gauge is a neat item to have around.

[@magga619]

if you are tapping something you want to last or using a smaller tap which can break more easily you should really turn back 1/4 turn every turn

[@handymanPF]

magga619 Thanks for watching. I always say follow the directions of the manufacturer. But turning back every 1/4 inch is a good tip for people to follow.

[@stever5887]

That is standard practice for anyone cutting new threads. The purpose to backing it up frequently is to break the thread material (slivers of fine metal) so they release and come out through the relief slots cut into the tap or die. If you didn't, you'd soon lock up the tap/die with slivers and be unable to proceed.

[@emc2184]

AND, ... you could break the tap itself, inside the job making it a really, REALLY SHITTY job to carry on with.

[@jacobcurley3424]

Can you just use the bolt on the threads cut by the tap? I have a tap set but no insert kit

[@frandanco6289]

Jacob Curley - Im thinking if you want to use the threads cut by the tap it will have to be a bigger bolt, and it might be too thick to go through the rocker arm, in this case.. By inserting the correct thread helicoil into the tapped hole, you have the same conditions for the original bolt, before it got stripped out..

[@rm42749]

This guy does almost everything wrong but it worked. Look at other vids if you want better info.

[@handymanPF]

That statement contradicts itself, that I did everything wrong but it worked. If it worked, then how is it wrong. Regardless , thanks for the comment. All comments are welcomed.

[@jeremylindemann5117]

I sort of agree, he got the job done but the method was a bit careless and could easily have gone wrong. He should have removed the head before doing any drilling, leaving it on the engine like that is asking for trouble. The metal shavings could have easily gotten into the engine, especially when removing the paper towels AND using the air gun to blow them off. You could see the left port was exposed. The drilling and subsequent re-threading should be done using some sort of assembly that holds your tools at the right angle and prevents movement. I have to say this is a good example of non-professional backyard mechanics. I think the guy know what he's doing and he's got experience but what also shows through is the slack, approximate way of getting things done.

[@dylanwalker2111]

Jeremy Lindemann yeah yeah Git R done!!!

I currently need to rethread a hole in my brake caliper mounting bracket for the guide pin bolt, would this be a possible solution, considering the bolt opening is open ended?

[@hotapplepy]

Caliper mounting bracket guide pin has no (male) thread. It just slides in and out. If you are taking about the hole on top of the guide pin which is used to hold the piston unit, then yes the guide pin does have (female) threads. However, why not change the guide pin itself? you will be changing both at a time! Easy and most imp, safe!

[@alexaraya2018]

[@thereviewer4173]

Check the bolt/nut markings (for material grade/strength) to help you determine if it was designed to be a metric or standard/SAE. You cannot always rely on the tool size that was used to remove the nut/bolt because metric and SAE sizes can be very close. There are bolts, for example, that will accept an 11 mm wrench, but were actually designed to be used with a 7/16” wrench because the bolt markings are SAE. If no bolt/nut markings, then thread pitch gauges are more reliable to determine if it’s metric or SAE than trying to go by the tool size used. Another way to determine if metric or SAE is to find whether your vehicle uses mostly metric or SAE bolts. Now, there may be exceptions, but generally, the bolts used to fasten parts onto the engine block (also known as mounting bolts) will be all of the same measurement type. Now, individual parts may be different than the engine. The nuts and bolts used within that part (say, an alternator) could be different than the engine nuts and bolts. However, the mounting bolts of the alternator likely belong to the engine.

[@handymanPF]

Yes I have a video for that also and here it is kzbin.info/www/bejne/ZnvEnqB4hLuNbtk

[@thereviewer4173]

@@handymanPF I think you mentioned that based on the tool size, you knew it was a metric or SAE, but that’s not always a reliable method to determine if it’s a metric or SAE. But it’s good you do know about bolt measurements. I learned this stuff mostly on my own about 2 years ago because I couldn’t find a video like yours. Hahaha. I remember thinking that the wrench size used would help in determining if it’s metric or SAE, but I soon found out that that method wasn’t always reliable.

So when you drill the damaged threads out. The actual size of the hole doesn’t increase? So that the original bolt will fit like a glove?

Majority of the time the hole is drilled slightly larger then the original size and then traced with the new threads. Because it would most likely be to tight if it was not drilled a little larger.

You neglected to break the tang and remove it. I would recommend measuring the depth of the blind hole and marking the drill bit before drilling.

[@JoeMamaCausesEarthquakes]

So you drill all the way down to remove the old thread?

[@azpete6436]

seb pesky I would. The insert will likely not clock the same as the original the original threads, so you should not expect the bolt to pass through the insert into what is left of the original threads. I mentioned marking the depth on the drill to avoid deepening the hole and perhaps interceptina a water jacket....I would make sure I did not drill the hole deeper, in other words.

When you tap it.. Can you put a bigger gauge bolt in?.. Is the coil just so you can fit the exact same bolt?..

The coil insert is the new threads. If the application allows you to put in a bigger gauge bolt then I do not see why not. Just be careful. Most of the time you cannot go to a thicker gauge bolt .

[@twistedcobra]

Got a question not about a hole with stripped threads. I want to know if you can tap a hole with 12Mx1.25 to 12Mx1.75 with just a tap and no heli coil?

[@darinclay6838]

NO. You'll end up with a nice smooth hole with no threads. There may be enough steel bits from the "threads" left to screw the bolt in but it will strip immediately.

[@thereviewer4173]

Why not go to 12 x 1.5 instead? You will probably need a drill bit to keep the threads from being too deep/long and breaking. I would think it can work if done correctly. Or you can also go to an even higher size and creating new threads with a totally different bigger size, assuming you have the space to do the work and fit the bolt.

I'm goimg to drill the 1/2 inch portion with a 14.5mm drill and them use a 14mm hand tap (plug type). Any opinion? Wont hold you to it if I screw up (lol). Also. are the coils necessary ? Been researching for couple of weeks, never done before, got to soon. Kia wants $800.00 bucks......not going to happen.

Hi there, I got a couple of questions. 1) why do impact guns do no harm to wheel nuts but yet can strip the threads of bolt holes? Where I live, mechanics use impact guns to fasten wheel nuts all the time. 2) Can tightening subframe bolts with an impact gun instead of a torque wrench cause the chassis' treads to be stripped? (I suspect this was what happened to my car, the handling is a little off now. An amateur foreman might have overtightened something).

[@jweiss03706]

Andrew Chan funny you say that. My wheel hub and lug nut are stripped from impact gun. I need to do this to wheel hub so I don’t have to pay $1,000+ to replace the wheel hub. Exactly why I watched this video! Hope it works!

what about a stripped bolt hole in the rear differential? does the differential and drive shaft need to be pulled in order to heli coil it perfectly straight or can it be done on the car? also with the amount of torque it has will it hold up well?

I am doing this job today on the same part on a ride on mower, i was installing a brand new head on my kohler courage and torqued the rocker stud to the spec. It got about 3/4 way there and then i felt it was not going to get there. Not what you want to feel on a new head.

[@handymanPF]

Yeah, that’s what happened too this one. I think the torque specifications are wrong

[@deant6627]

The torque spec for my one is only 13.5 newton metres, lol it didn't take much, the repair all went well, i got a bit worried when the coil started getting a bit tight to turn in near the end but it got there. Thank you very much for your video, it gave me the confidence I needed to fix it.

2014 chev cruise and someone stripped out a valve cover bolt. M6 30 with E10 socket bolts. What would I drill and retap bolt hole with?, drill bit size and rethread size?

[@handymanPF]

You can try this kit. It comes with everything you need including the drill bit amzn.to/3J0At4w

[@felixsegovia7782]

Does it work on metal like the Block ?

[@justinp8946]

I didn't use a drill but the coil is installed and seems good?
