Many years back when I was an apprentice we used to make a control panel that was one inch thick aluminum and all the drilled holes on them to mount components we used to helicol them. the bolts where 3/8 UNF and driving in to aluminum you could strip the thread you could get some aluminum binding into the thread and snapping the bolt off. Using helicols overcame these problems. We used aluminum as it acted as a heat sink. Great videos Adam I really enjoy watching them each week.
I'm always grateful for positive comments in among all the folks who think they are Adam's teacher and could have done it better. :) I'd be happy if he lived his entire life only knowing what his dad and grandpa taught him, plus what he's figured out for himself. That's what life is about.
I'm a Helicoil expert, the resistance you felt while loading the insert into the installation tool is because of the coil size, it is designed bigger than the SPI tapped Hole so when you release it it will expand and lock in position, Helicoil do not recommend using thread locking or lubricant or corrosion inhibition CPCs products, a clean dry hole is good enough for self locking. Helicoil recently updated their installation tool, now its made of Steel, the designed you have used is still available however in bigger insert applications the body will twist and the hot bonded insert threads will be damaged in heavy/production usage

Good job Adam. We have saved our customers a lot of money when brass threads in one part would wear and strip because the mating screw was stainless steel. After drilling, tapping and installing a Helicoil, the customer received a repair that worked better and lasted longer than the original part.
23:00 I've worked on industrial equipment with aluminum parts, that come factory original with Heli-Coils in every bolt hole. Reason being it's stronger than just using a tapped hole in aluminum.
I always put a dab of thread lock on the helicoil before I insert it, as I have had a few wind out on my when taking the bolt out, but I know it shouldn't be needed :)
Adam, watching how much care you put into something as simple as removing a broken bolt...... I think I might have enjoyed meeting your dad and your grandpa. I'm sure the Apple doesn't fall far from the tree. 😉
For any performance type work, I tend to Helicoil all mission-critical bolt holes. Valve covers tend to be a common PITA. Ally threads fatigue over time, especially where bolts are removed regularly and constantly overtightened. Great job Abom.
Like seeing how you deal with rust (like the American Pacemaker levelling screws) and broken bolts like this. Helpful for me out in the garage working on my cars in the salt zone. Not the most fun projects for you, but definitely helpful for me! 👍 I've been using the CRC Rust Converter since I saw it on the channel and it has worked great for me. Appreciate it.
One thing you might try is if you use a left-hand drill, and progress stops. Go back to a right-hand drill. Move the broken piece down a little. Then chase with a bottom tap and go back to the left-hand drill. Usually this is caused by chips jamming in the threads as you are backing out. What you can do to combat that is give it more pressure on the left-hand drill. I have found if you push hard enough to get little or no chips on a left-hand drill you usually don't have issues. I guess you could say think of a left-hand drill as more of an extractor than a drill.
Nice job. I am 71 yrs old and machined in a job shop all my career, about 30 yrs. I was surprised to see the General ratcheting tap wrench. I thought I had seen it all that was a first. The heli coil repair was great.Why not a drop of blue loc tite on the helicoil .
Heli-Coils are great eh? Been using them for over 40 years and they can be a lifesaver. Thanks for showing the proper way to use them, some people may have not have noticed that initially.. I'm sure the owner will be very thankful. Repair is also much stronger than the original thread.
No matter how you drill since the fragment isn't ever broken level a drill can sway especially into soft materials. The availability of Heli coils is a blessing as you said. When it comes to drills hope it bites true and run with it. Keep up the videos I aswell as others enjoy them.
@@TheDennisZb If he doesn't have the tubing in stock or a small enough lathe chuck, and doesn't want to drive to the store and spend a dollar, then cut out a piece of sheet metal with tin snips and roll it around the 3 or 4.2mm bit. What, you want to just jam a bit in there without even using an endmill to face it off, walk the bit directly into the threads, and then helicoil it without the counterbore the other holes have so it probably won't even go back together, and if it does it'll be out of balance?
While echo the sentiments of the viewer who questioned why go through all this trouble and expense on a $150 part, I very much enjoyed watching your meticulous work. I can’t tell you how many parts and machines I have thrown out in frustration over a broken off stud or bolt. My bench top mill is too small for a job like this, but I long for the satisfaction you must have felt at the end of a job done well.
What a pleasure to watch a professional ! After struggling with a similar repair on an aluminum cylinder head, (just a coil pack hold down, not critical), I see where the correct tools and more importantly, the expertise, gets it done right. Used a very old (30+ years old) metric Heli Coil set with the older version of the installation tool. Looked similar yours where the insert in dropped in the window, but the nose & threaded section was longer & all plastic. Kept breaking the tang while winding it out of the tool into the work piece (very hard to turn - threads damaged likely). The new prewinding tool you used looks to have cured that problem. As with you, McMaster had the inserts there the next day (after breaking all the inserts I had on hand).
Done many of cases in my lifetime. 42 years of wrenching on all sorts of bike. One of my mentors was Arlen Ness himself when he was in San Leandro. He used to teach how to build your own bike from the ground up during his time there. He was the real deal and a very nice man compared to the Tards like Jesse James or anyone coming from the OCC crowd that actually knew on how to build a bike. I was taught by the best and I respect the man who gave out his teachings to anyone who wanted to learn. Also Indian Larry was also a great man. I don't fully trust any Harley built after 2000. The quality on certain parts were just not there. People used to make fun of the FXR or commonly known as "The Fixer". From 1987 to 1991 they had front end issues as well as really crappy cylinder head seals issues (which was on all models). Well my 1993 FXRS Low Rider Convertible is arguably the best motorcycle Harley Davidson ever made. That model had all of the issues taken care of from previous bike. The 94 model was a transitional model to the Dyna, which I consider inferior to the FXR. The 93 model was virtually bullet proof and so dependable IF you leave it at stock. By the Way a original Stock FXR will get its money back or more. Not too be for my 29 year old bike. You can not get your money back on newer HD's nor customs. Breaking bolts is rather more common on newer models than the 80+ something bikes that I used to work on (retired from wrenching other people's bikes, only my own). I think the quality of material used was inferior in certain places to increase more profit than those bikes made in the late 80's to early 00. And oh yea. Heli Coils ARE your friend when dealing with broken bolts on a case. Other real good bikes IMHO are the R series of BMW's and ironically the humble Honda SilverWing which I was really impressed on how durable that bike was. I've also owned Suzuki dirt bikes and cafe' racers in the 70's and a Ducati Monster.
@@paulcopeland9035 yeah, it was all setup in the mill for broken bolt removal... Off camera my guess is another 30 minutes and all 3 holes could have been 'coiled.'
I'm not a machinist but I put the helicoils in the recess in the tool and wind it through tool so it stretches it to the correct pitch when installing.
I used to see this happen when I was a line mechanic "back in the day" (some even before Adam was born). Often an owner had a slipping clutch and thought that tightening those bolts would help. Snap! 99% of the time we could back it out, luckily. But we'd not spend much time on it, it wasn't that expensive to replace.
Wow when you mentioned that tap handle (General), I remembered I had bought both sizes they offered at Sears at the time.Miss the walks thru the Sears tool department :(
Glad you showed the proper way to use the help-coil tool lol as you were threading it in I was kind of cringing. Glad it worked though! Personally I would use a small endmill to drill through the bolt and then use an ez-out. Less chance of breaking a drill in there and messing up the threads.
Adam, I was cringing when I saw you didn't put any cover over to bearing. Just seeing the chips made me shiver . Is there a moto tool stone bit with a flat bottom that would fit in the hole and grind the bolt top flat? Then center drill and extractor!
I much prefer the timesert kits to helicoil. I may be biases because Honda required timesert for factory repairs but I always it to be less trouble in the long run. I always manage to get the helicoils to come out with the bolts when I use them.
James T Smith. -- 45 years of experience doing this sorta repair tells me to observe, listen and possibly learn. Abom79 just shared a method of removing a broken bolt. Variations to that are a personal choice. He drilled out a steel bolt out of cast aluminum. Those threads were probably damage anyway. The end result was a properly repaired hole. To comment, "You made a lot of mistakes" isn't deserved for a really good how to video. "Food for though"
You did more than I would have, a damaged M6 thread is the reason M7 exists in my opinion :) sometimes not the easiest size to find the right fasteners for though.
Hope this episode will keep keyboard warriors (from previous one) happy that you've shown some machining 👍 great work as usual, nicely done and explained
Heli coil are touted to be a stronger thread than original threads. I personally think anything aluminum should have them placed as factory production line work in every threaded hole. I've used them many many many times for repairs.
Previous vids you ran a face mill down 1st to sqr the broken stud up with. You did not do it this time? Could this of contributed to the 1st 5mm drill jumping off center? I now follow your advice with the end mill and had a lot of great luck and success. Cheers
Hi Adam, when I saw that install tool for the Heli-coil I thought ??? Abom could easily modify that to work with the centring tool in the mill, so as when screwing the coil in it's not wobbling all over the place, just sharpen the angles on the crank and put a centre on the shoulder of the first bend of the crank, place under the mill, find your centre and start to crank down, nice project for you maybe, anyhoo good job on the piece, all the best from Aus, Al

Actually used my L/H drills on some counter sunk screws that the slots were stripped out those screw came right out Just like they were suppose too which made me really happy
My personal preference is for timeserts as they are a bit more robust and can be loctited or peened to prevent them from moving, but great job none the less. Keep the videos coming 🙂

Most of the time bits that are inserted back into the drill index upside down is due to a burr on the shank of the drill bit when it spins or slips in the chuck. A light touch on a strip sanding belt will take off the burr without affecting the roundness (concentricity) of the shank.
Nice job! Set up and line up most important! I have some short shank tool steel in different sizes ground left hand with minimum short flutes ground in just in case it grabs and stops so I'm not having to drill out a broken drill! Thanks for your time and sharing! 👍😎
@@paulmanson253 I eyeballed a left hand drill point on the stock and added a small hand ground helix. Drilled in short steps to not fill the short helix. Has served me well for over 50 years.
fun video. i have seen you feature a parallel splined extractor set on your channel in past a vid. i have the same set that i relied on heavily as a long-time automotive tech. it has some really nice, hardened drill guides that will keep you centered even if the bolt is broken at an angle. drill a small pilot and you are off and running. love your channel, avid viewer, interesting content. thanks for sharing.
What I'm wondering with these operations: you want the left handed drill to bite into the material, however the center causes you to need a lot of pressure for it to bite. Wouldn't it be a good idea to predrill it with a very small drill to relieve the center? Or maybe even use a center drill if you can. I didn't have the opportunity to try this yet, but would like to see if it works.
I always use red thread locker lock tight on the heli coils, but to be honest, I got away from heli coils all tougher and use the shouldered inserts now, they can't back out however I've seen many heli coils back out even with red lock tight.
Who knows the headache, effort, money, and people time to come up with a simple cost-effective solution to a problem that had to be addressed...or else they wouldn't bother... just for some guy to show how to use it as not intended. As an engineer (admittedly not a mechanical one) as much as I learn from these guys on the tube, there's sometimes I just want to thunk them in the forehead, what did that shortcut save? and what happens if it skips or binds up? it essentially is a spring FFS no one has twisted or stretched one of those!
@@osgeld just curious. what is the chances of a helicoil jumping a thread in a newly tapped hole? is a helicoil pretty weak? i have never even seen/held one so just wondering
Could one make a drill guide out of a bolt that fits the hole, by drilling out the center? Thread the hollow bolt in and then drill through it and into the stuck bolt, making a perfectly centered pilot hole for subsequent drill bits. It would be a little more work but might preclude using a Helicoil. Just a suggestion.

It is a good idea, however the heli-coil is the proper repair for this project. Inserts in the other two mounts is also part of the correct repair. Ask any Harley mechanic.
I remember when i had to do extractions at work some weeks thats all i did catapiller exaust studs. Left hand drills where the best opt. My trick was the hit the stud on the end shocking threads then out they came.

I do not know if this exists but a center lathe drill with different OD's for different threaded hole sizes? If this does not exist, one could buy different sizes and grind them down for differing threaded holes. These bits could be used for broken bolt removals. Main objective is to protect the threads from thinning by the drill bits. Also one could make a set of guides out of brass with the inner thread crest size in mind. Just a thought. Thanks for the close ups, it is almost like being there.
I can't even guess how much it would've cost to replace that part because I doubt the dealer would take the time to extract the bolt. It is cool the amount of patience and persistence required to not make the piece scrap.
"I can't even guess how much it would've cost to replace that part " A wild ten seconds of googling shows that Harley clutch baskets are anywhere from $200 to $300 so the question is; can the dealer get it done in less than two hours? And is the dealer able to fix a "mistake" like Abom did here where the threads ended up too loose, or will you just get a drilled-out piece of crap back with an apology and an invoice? And hat happens when the dealer does "fix" it and you install it and the new threads loosen and you end up destroying your engine? Who's to blame, you for not using original parts or the dealer for a bad fix on a part that harley probably wants you to replace anyway, given that it's "only" $300?
In my opinion you're running the LH drills far, far too fast. You actually don't want them to cut, you want them to grab, so the speeds & feeds for drilling are useless. If it starts drilling, that's fine, but stop! Then go to a tapered extractor. The moment you felt it "trying" to come out, there's no more need for cutting.
Adam, those bolts break on disassembly because Harley recommends replacing the complete loaded basket as an assembly, nice job though. I think the loaded basket is $400.00 plus.
There is an indescribable joy when a left hand drill bit walks out a a broken bolt
It kinda like being Harry Potter …. If just for a brief moment
I felt it just watching the video.
I’ve only had one or 2 work, I usually have to use an easy out.
It’s that brief moment of we will never talk about this
i was dissapointed when i heard the threads were damaged😟. he shouldnt have told us😭
I don't care how many broken screws or taps you remove, when you are successful at removing one, it makes for a good day in the shop!

I used to see this happen when I was a line mechanic "back in the day" (some even before Adam was born). Often an owner had a slipping clutch and thought that tightening those bolts would help. Snap! 99% of the time we could back it out, luckily. But we'd not spend much time on it, it wasn't that expensive to replace.
I have used this tool, Ridgid Screw Extractor Set No. 10 and have had good results. I enjoy your videos. Thanks
Wow when you mentioned that tap handle (General), I remembered I had bought both sizes they offered at Sears at the time.Miss the walks thru the Sears tool department :(
Love heli coils. If you don't know they even make inserts for spark plugs. So far I've never had one fail on chainsaws.
I can watch your mastery forever! (I am more of a hacksaw and file man myself!) :-)
Glad you showed the proper way to use the help-coil tool lol as you were threading it in I was kind of cringing. Glad it worked though! Personally I would use a small endmill to drill through the bolt and then use an ez-out. Less chance of breaking a drill in there and messing up the threads.
Adam I love every video you put out. but love your machinist videos for sure
Looks like it to me that the OEM threads had a counter bore before the threads started but the Heli-Coil is right at the top.
How is a 19mm helicoil sitting at the top of a 30mm hole? Just because it's not in Bananas you can't follow the video anymore?
Thanks for at the end showing how to use the tool properly.
Little details can improve the outcome of the job.
Adam, I was cringing when I saw you didn't put any cover over to bearing. Just seeing the chips made me shiver . Is there a moto tool stone bit with a flat bottom that would fit in the hole and grind the bolt top flat? Then center drill and extractor!
Nice job I nearly always use timesert or bigsert for thread repair
I've done a few broken bolt extractions on old fordson tractor manifolds over on my channel. They sure can be stubborn.
what about the counter-bore for the bolt shank?
I much prefer the timesert kits to helicoil. I may be biases because Honda required timesert for factory repairs but I always it to be less trouble in the long run. I always manage to get the helicoils to come out with the bolts when I use them.
Hi Adam ..... Your intro music is my wind down marker.. Thanks so much for your efforts delivering your knowledge to us you tubers !!
James T Smith. -- 45 years of experience doing this sorta repair tells me to observe, listen and possibly learn. Abom79 just shared a method of removing a broken bolt. Variations to that are a personal choice. He drilled out a steel bolt out of cast aluminum. Those threads were probably damage anyway. The end result was a properly repaired hole. To comment, "You made a lot of mistakes" isn't deserved for a really good how to video. "Food for though"
For bolts like this one, you can try pressing a torx bit in a small hole next time and use it as a bolt extractor.
That does work but sometimes it expands the bolt and makes it bite even harder.
Nicely done buddy, thanks for sharing 👍
You did more than I would have, a damaged M6 thread is the reason M7 exists in my opinion :) sometimes not the easiest size to find the right fasteners for though.
Tony would be proud of your own This Old Adam style of talking machinist hands video. 😅👍
Should all three holes be helicoiled so as to keep it in balance?
Well done Adam!... that was interesting to watch. Again I learned something new. cheers, Blessings!!
Hope this episode will keep keyboard warriors (from previous one) happy that you've shown some machining 👍 great work as usual, nicely done and explained
I've never seen a helicoil. That was pretty cool and thanks for sharing.
@@calholli i think he said it was a subscriber job, there may not have been any money changing hands as the vid makes more money, just a guess
I saw the first time over 50 years ago,
Yes,,,another Harley back on the road 👍😜. Now a waiting you to show the Meet & Greet at the 2022 Flying Wheels event over the WK end 👍👍🤠
Heli coil are touted to be a stronger thread than original threads. I personally think anything aluminum should have them placed as factory production line work in every threaded hole. I've used them many many many times for repairs.
Previous vids you ran a face mill down 1st to sqr the broken stud up with. You did not do it this time? Could this of contributed to the 1st 5mm drill jumping off center? I now follow your advice with the end mill and had a lot of great luck and success.
Cheers
Hi Adam, when I saw that install tool for the Heli-coil I thought ??? Abom could easily modify that to work with the centring tool in the mill, so as when screwing the coil in it's not wobbling all over the place, just sharpen the angles on the crank and put a centre on the shoulder of the first bend of the crank, place under the mill, find your centre and start to crank down, nice project for you maybe, anyhoo good job on the piece, all the best from Aus, Al

I consider this a win, threads probably weren’t that great to begin with. Nice job 👍
Was I the only one trying to blow the chips out off the hole.....lol

Nice repair!
Actually used my L/H drills on some counter sunk screws that the slots were stripped out those screw came right out
Just like they were suppose too which made me really happy
Good job as always, Adam.
My personal preference is for timeserts as they are a bit more robust and can be loctited or peened to prevent them from moving, but great job none the less. Keep the videos coming 🙂
4:34 Are the upside-down bits awaiting sharpening?

Most of the time bits that are inserted back into the drill index upside down is due to a burr on the shank of the drill bit when it spins or slips in the chuck. A light touch on a strip sanding belt will take off the burr without affecting the roundness (concentricity) of the shank.
Nice job! Set up and line up most important! I have some short shank tool steel in different sizes ground left hand with minimum short flutes ground in just in case it grabs and stops so I'm not having to drill out a broken drill! Thanks for your time and sharing! 👍😎
Sounds like you did that yourself. How ? Just angle straight grind,or did you provide a helix of some sort. Sounds like a smart DIY gadget to have.
@@paulmanson253 I eyeballed a left hand drill point on the stock and added a small hand ground helix. Drilled in short steps to not fill the short helix. Has served me well for over 50 years.
@@jameslezak8179 Whatever works.
1 question since its a rotating high peed what do you do for the different thread weight for vibration?
It’s a Harley. Nobody will notice the extra vibration.
Not an issue. At the max rpm of that engine, it would be impossible to measure such a small balance issue.
fun video. i have seen you feature a parallel splined extractor set on your channel in past a vid. i have the same set that i relied on heavily as a long-time automotive tech. it has some really nice, hardened drill guides that will keep you centered even if the bolt is broken at an angle. drill a small pilot and you are off and running. love your channel, avid viewer, interesting content. thanks for sharing.
You’re a good man Mr Abom
Love watching you get those broken bolts out.👍
That heli coil tool at the end I have one ,wasn't sure how to use it,thanks
Love watching this show!
What I'm wondering with these operations: you want the left handed drill to bite into the material, however the center causes you to need a lot of pressure for it to bite. Wouldn't it be a good idea to predrill it with a very small drill to relieve the center? Or maybe even use a center drill if you can. I didn't have the opportunity to try this yet, but would like to see if it works.
Seems a logical suggestion to me.
If you are going to predrill the center may as well use an easy out and be done quick.
Beautiful work. You know how to do it the right way.
I always use red thread locker lock tight on the heli coils, but to be honest, I got away from heli coils all tougher and use the shouldered inserts now, they can't back out however I've seen many heli coils back out even with red lock tight.
Excellent work Adam pleasure to watch thanks david
18:00 Hey! :) I have the exact same tap wrench (mine is rusty though) I use it for the valve 'T' handle on my small acetylene tank :)
The resistance is intentional to keep the coil tight on the mandrel so you don't install it skipping a thread binding up and causing a bigger headache
Who knows the headache, effort, money, and people time to come up with a simple cost-effective solution to a problem that had to be addressed...or else they wouldn't bother... just for some guy to show how to use it as not intended.
As an engineer (admittedly not a mechanical one) as much as I learn from these guys on the tube, there's sometimes I just want to thunk them in the forehead, what did that shortcut save? and what happens if it skips or binds up? it essentially is a spring FFS no one has twisted or stretched one of those!
@@osgeld just curious. what is the chances of a helicoil jumping a thread in a newly tapped hole? is a helicoil pretty weak? i have never even seen/held one so just wondering
Sweet job will there be any problems with balance adding the heli coil?
It’s a Harley….. “balance” is a relative term
Not on a Harley. That's why the engines are mounted with rubber cushioning.
Could one make a drill guide out of a bolt that fits the hole, by drilling out the center? Thread the hollow bolt in and then drill through it and into the stuck bolt, making a perfectly centered pilot hole for subsequent drill bits. It would be a little more work but might preclude using a Helicoil. Just a suggestion.
That’s actually a great idea, especially if you make it quite a bit harder than a normal bolt.

It is a good idea, however the heli-coil is the proper repair for this project. Inserts in the other two mounts is also part of the correct repair. Ask any Harley mechanic.
it's off a Harley, if you don't use loctite, it will vibrate itself to pieces.
I wish fixin my Harley was that easy! Mine blew out the splines on either the clutch or the transmission input shaft
I remember when i had to do extractions at work some weeks thats all i did catapiller exaust studs. Left hand drills where the best opt. My trick was the hit the stud on the end shocking threads then out they came.
Great content finely some HD work

Fantastic video ,an amazing job 👏 👍
After installing the helicoil in the cast Al, now the other 2 are inferior.
So very true.
I do not know if this exists but a center lathe drill with different OD's for different threaded hole sizes? If this does not exist, one could buy different sizes and grind them down for differing threaded holes. These bits could be used for broken bolt removals. Main objective is to protect the threads from thinning by the drill bits. Also one could make a set of guides out of brass with the inner thread crest size in mind. Just a thought. Thanks for the close ups, it is almost like being there.
I can't even guess how much it would've cost to replace that part because I doubt the dealer would take the time to extract the bolt. It is cool the amount of patience and persistence required to not make the piece scrap.
"I can't even guess how much it would've cost to replace that part "
A wild ten seconds of googling shows that Harley clutch baskets are anywhere from $200 to $300 so the question is; can the dealer get it done in less than two hours? And is the dealer able to fix a "mistake" like Abom did here where the threads ended up too loose, or will you just get a drilled-out piece of crap back with an apology and an invoice?
And hat happens when the dealer does "fix" it and you install it and the new threads loosen and you end up destroying your engine? Who's to blame, you for not using original parts or the dealer for a bad fix on a part that harley probably wants you to replace anyway, given that it's "only" $300?
In my opinion you're running the LH drills far, far too fast. You actually don't want them to cut, you want them to grab, so the speeds & feeds for drilling are useless. If it starts drilling, that's fine, but stop! Then go to a tapered extractor. The moment you felt it "trying" to come out, there's no more need for cutting.
@@madjimbo4176 210 rpm
Adam, those bolts break on disassembly because Harley recommends replacing the complete loaded basket as an assembly, nice job though. I think the loaded basket is $400.00 plus.
Does it come with a new bearing too ? (since he washed all the grease out of this bearing ;) )
@@millomweb The bearing is sealed so no harm done but the basket assy. does not come with the sprocket, you have to reuse it.
@@carlwhite8225 Sealed for what - not thin aggressive cleaning liquids/solvents !
@@carlwhite8225 ....Pro tip: never argue with this guy about lubrication. He is determined to soak everything in oil.
Heli coils are stronger than aluminum should have done the all, keep em coming nice job
