Dear Mr. Pete, Thank you, may you live forever.Your knowledge and experience is priceless , you make the world a better place by sharing. Happy Thanksgiving to you and loved ones.
your videos are so great -- most others just show you a procedure, with no narration and maybe just a few words of text on the screen. i love how you are more than prepared to provide running information every step of the way.
interesting how metric and inch systems are used side by side more often nowadays. I am a huge follower of this channel and can't thank you enough for what you do
Fantastic video mr. Pete It is such a pleasure listening to you. Thank you for your very well done and very informative videos. Keep up the great work sir.
thanks pete i have a chainsaw with a bad thread (well no thread) and your video has given me total confidence in doing the job right, many thanks pete keep em coming
Thank you Mr Pete. They don't makem like you anymore. Happy thangsgiving I'm a young one 43 n learning as I go. Body work paint mechanics diff jobs on my own
Excellent tutorial. I popped a spark plug out of my rotavator today. I have a helicoil kit I was given but have never used it, this video has given me the confidence to try it out tomorrow. thank you mr Pete. All the best from Harrogate England.
Another great vid Mr.Pete. Last time I used one was on my small block Ford for the alternator pivot bolt in the front of the cast iron cylinder head. Lucky for me it was in my 63 Fairlane so I had the room to work. These thread inserts can be real life-savers in so many applications.Neatest things since sliced bread!
Great video! Very informative. I also have a kit with different type of inserts but the same tap. Im glad I watched this video because my kit did not come with instructions. My original plan was to drill the head with a 15mm drill bit and then tap it. Again I'm glad I watched this..lol
Back in the 70's I used to put a lot of those into motorcycle heads. Usually they were off the engine just like the one you used. I still have three boxes of them. Thanks for sharing.
Nice and instuktive again mrPete. I would remove the exposed threads inside the cylinder head to prevent glow ignition ( not sure if that is the corect term in english ). From mrHans in Sweden. My alias comes from when I lived in East Africa so I am not copying yours. :-)
Hey I believe that head is for a Lauson engine I have one like it on my water pump good vid the the threads for my continental small engine came out so I plan to install a helicoil thanks!
First used one with a borrowed Reliant in Alabama, (I had only been a few weeks in US) that lost seal on stat housing. I free wheeled down a hill, pure luck found an autozone, bought kit, no drill, but got tap in, then coil & it sealed. Such a relief! It worked for a long time afterwards.
Hi there Mr Pete These are a great fix I used the 1/4 " ones on my coin slide mechanisms on my MAYTAG washing machines as you may know the coin slides are a type of aluminum casting so actually the coils are stronger than original. very good video,s you re making. Thank you.
Takes me back to my Apprenticeship we had to learn how to use Helicoil to repair threads, taught a young lad how to use them a few months back and he was amazed he really thought he was going to have to purchase a new head.
As Mr Pete mentions, "Heli-Coil" is a trademark. The generic term for these taps and coils is STI (Screw Thread Insert) and will be marked "STI" or "Heli-Coil". Its pretty easy to mix up standard and STI taps (ask me how I know!). The coil's thread pitch is the same inside and out (which might be pretty obvious). The only difference is the STI tap's and coil's outside diameter is larger than the original bolt. The STI tap cuts to the outside diameter. You then install the coil insert and then the pitch and diameter are as good as new!
Being they're super hardened BRITTLE steel they obviously should not be stored together. I just drilled a 2 by 4 and have all mine standing up like little soldiers except for an electrical set I use when people put wood screws in the light switches because they took them off to paint. I wish people like that would just paint over the light switches if they can't figure out the difference between a wood screw and a machine screw! (or are too lazy/cheap to go to the store and get the right one!)
Time Sert is the new big thread repair kit, mostly used for engine block head bolt holes. The Time Sert is much larger than a Heli-Coil, and a Time Sert is actually stronger than the original tapped holes. Toyota I-4 engines are famous for ripping out head bolts, when the heads warp.
The HeliCoil set has been using that plastic applicator for at least 25 years now, maybe 30 or 35 years? I bought up a big box of brand new SAE HeliCoils, and Metric HeliCoils for maybe $5 or $10 each, per set, in 20 or more sizes. I bought every single one the guy had, but he usually always cut me some really great deals. The man is Vietnamese, and I always treated him with utmost respect, so he always gave me really good deals. The people I got some of my tools from have more value than the tools themselves, especially the old guys that are long dead and gone now.
Heli-Coil saves the day! I've installed a few... in the engine compartment. Gota be careful, you usually only get one chance. Many high end aluminum engines come with steel threaded inserts from the factory. You can adapt a airline to the intake and blow the chips out that fall in. Either way, if it works, it's faster and cheaper than tearing a engine apart...
mrpete222 I heard of using compressed air added to the oil gallery when drilling and tapping VW engines for "full flow" oil filter addition. Figure it could applied to other situations. Maybe a common trick to "those in the know", but was new to me.
Tubal Cain !....... did you or your company used to put adverts in the british motorcycle news in the 1970,s ? the name rings a strong bell from my past memories . Excellent video in great detail .
I did not. But there was another man from England that use that name. His real name was Tom Walsh, deceased. He wrote many technical books and magazine articles
Nice to see a demonstration of how it's done. Looking at how far recessed the sparky end of the plug is, I wonder if the engine wasn't designed for a longer reach plug? Some time ago I bought a set of plugs for my car from an autoparts place and the threaded end was much longer than the ones I had taken out. After putting one in and turning the engine over by hand to be sure there was no interference, I put the rest in. The dealership service people had put the wrong plugs in! Car ran better too.
MrPete When using a Helicoil for a spark plug make sure that the insert is longer than the spark plug threads. If the plug threads are longer than the insert 2 problems can occur. The first one is the protruding threads can glow red and cause preignition. the second is that carbon can build up on the protruding threads and when the plug is removed the insert comes out with the plug.
Very good, the same thing happened to me 2005 Fatboy, taken out spark plug when it was warm the helicoil brass collar came out with it. My indie put new heli coils in cause spark plug was hard to get out. I bought the whole set/kit for 200, Just hoping I have room to retap with the tank on and head still on the bike?? What do you think
The older packs were a steel ,box with steel dividers for all the inner tools, later ones are plastic with a foam and plastic set of holders. I bought some really cheap as I wanted imperial sizing in a metric country, so the ones I got had been sitting in a store since the 1970's, and those had the nice red steel boxes. The other brands of spark plug repair kits use a solid machined steel block that is around 3mm wall thickness, it works well and will not come out with the plug easily. Does need a jig to set up the drill and tap to be perfectly aligned with the hole though. Nice thing is that if you do not have a long enough insert ( for deep holes) you can just us a few in the hole, they will all be aligned perfectly.
Thanks for a very informative and entertaining video, thoroghly enjoyed it! Loved the closing comment - 'just like downtown', figure that must be an American term meaning something like 'just the way a professional would have done it'?
Hello Mr Pete , if doing a thread in an engine in situ , when one has recut the threads in the head just give the starter a whirl an all dem Chips will fly out of the head at mach 1 !!! yes ! regards to you mr pete , Pete scales......
I work repairing TV News cameras. They have magnesium-alloy bodies and every screw hole all the way down to 2.6mm diameter tends to have an individual heli-coil style thread inserted. That way immense loads and holding by such small fastenings can be assured. I had to use a heli-coil on a late model car i own and it had just come out of its warranty right when it developed a nasty oil leak. I traced the source of the leak to the 4 cylinder twin-cam cylinder head where it had an 8mm bolt holding in a small support bracket. There was also a camshaft cover ontop of the cylinder head so i removed it and discovered the 8mm bolt had been installed at 30degrees(!), stripping any threads and entered the oil flow area (normally, design would have allowed more cast area there). After thread repair the new 8mm bolt had some thread seal added. The engine in that car hasn't dripped a bit of oil since. (i LOVE Heli-coil)....
Be interesting if you had pretended it was on engine and used grease, and then when done see how much cuttings fell on table, and to see if cutting fluid wipe of the grease causing cuttings on table... As usual, another great video.
Got the same helicoil set. Never had much luck with it. Especially frustrating are the 3/4 reach which I've ruined multiple inserts. Seems they get to a point, then tool very hard to turn and then jambs before helicoil gets out of the tool. Any idea what I might be doing wrong?
I use these quite a bit on trucks. i just tap the hole and blow the cylinder out with shop air, then i run the engine for a minute or so with the plug out to get as much of the shavings out as possible. I'm not to concerned about the shavings ruining the engine because its just aluminum but you wouldn't want it in the cat
Thanks for showing this ! My problem is I have a Craftsman cultavtor 4 stroke one spark plug that's strip out has aluminum head I never try or know much bout back tap 10mm or heli. -coil plug is taper that's in head. I try my 10mm back tap it made new threads at the bottom of hole but who ever owned machine before me either try a coil or mess up the threads the plug was quite sloppy when purchase used now I was told by repair small shop I need to repair with Heli coil using 10mm x 100 pitch and he don't have that size kit so question is it possible to save this engine block? I got $100.00 in unit plus 32.00 for back tap now was told heli kit Any help appreciate Also in your clip you stated Kit Won't work on taper plug is this true??? Louie
Wouldnt the area that is enlarged by the helicoil tap, but not covered by the helicoil, lower the compression ratio of the engine? Also, have you used timeserts? I like those better than helicoil.
Do you have any other videos about working on old Clinton engines I picked up a K201 Clinton two stroke boat motor and it appears that it may be seized any tips
mrpete222 you say if not using aluminium cutting fluid you will ruin the hole for sure - can you explain why? my guess is something to do with aluminium shaving clumping with a different visousity oil? the fluid you used appeared very thin. thankyou
Interesting how they measure the thread diameter and pitch in metric, but the reach in imperial. Also, wrt tapered spark plug threads, if you had the head off, I guess you could drill out the tapered thread, fit an insert, and then use a straight thread spark plug instead.
Wish you had the engine and a video about it. Those old 2 stroke Clinton’s ( I’m guessing that’s what the head is from) are as old as we are, or close.
Beware of cheap imitations! The one I bought used a standard socket wrench for the tap. The problem being after cutting the threads the tap fell into the cylinder!
Woulnd't you say that was user error? In my experience most people run a tap farther than they need to because they're not thinking straight about the details in the first place.
A question on the tap wrench: I was taught, many years ago, that with the jaw style yours has, the wrench should be the other side up than you had it so that the long face of the jaws bear on faces of the tap square as well as inside corner of the jaws, in a similar way to proper use of a crescent wrench. Does it matter, in your experience? As a side note, Heli's are the cat's meow in gray cast iron. I tend to use a different brand with a little serration near the bottom end that keeps it from walking.
Great video brother That's how a professional works, I'm doing this trick to a heli coil that came out, got loose. Out of my spark plug hole. I have a 2005 Harley-Davidson Fatboy M12 * 1.25. you had the exact same size as the other box that you showed us with the orange and white lettering. Going to try to do it while the head is on the bike with the gas tank in place do you think 5" in will give me that clearance? Thank you in advance.
A tip I learned at Ford engine school If you have to do inserts with the head on the engine put the cylinder at bottom dead center of the compression stroke and fill the cylinder with foaming shaving cream ( Do NOT use the gel type) drill and tap then install the insert. then crank the engine over to blow the foam and any shavings out of the cylinder.
Thank you very much that sounds crazy but I'm going to use that method I have a 2005 Fatboy and I'm not taking the head off the engine and I'm not removing the gas tank, the shaving cream won't interfere with the oil Will everything be okay???? I love it if it works who's better than you I thank you in advance please reply. Just save my day
@@-MrRichBiker1967 I have only done it a couple of times and as far as I know it didn't cause any issues with the oil. If you're worried about the cylinder walls getting stripped of the oil film you could put a couple of squirts of oil in the cylinder and bumping it over before putting the spark plug back in.
I'd advise removing the head rather than doing this in situ, like you say you don't want tap shavings in the cylinder or goodnight bore! great vid though. a true gent passing on knowledge. kind regards
Autozone has better insert kits with a metal tool. It works in taper and gasket plugs. On cars with deep spark plug holes get a Time sert kit or better yet a Big sert kit. Get the one with the long tool.
long ago I worked at a shop where the owner used "KD" inserts.these were basically threaded tubes as the man hated helicoils for some reason(price?),anyway I wondered if you used or even heard of "KD" inserts and if so do you have an opinion?

Wouldnt the area that is enlarged by the helicoil tap, but not covered by the helicoil, lower the compression ratio of the engine?

A question on the tap wrench: I was taught, many years ago, that with the jaw style yours has, the wrench should be the other side up than you had it so that the long face of the jaws bear on faces of the tap square as well as inside corner of the jaws, in a similar way to proper use of a crescent wrench. Does it matter, in your experience? As a side note, Heli's are the cat's meow in gray cast iron. I tend to use a different brand with a little serration near the bottom end that keeps it from walking.
+john john Thanks for watching--you are probably right on the wrench-I never noticed. But always used a crescent the correct way
Great video brother That's how a professional works,
I'm doing this trick to a heli coil that came out, got loose. Out of my spark plug hole.
I have a 2005 Harley-Davidson Fatboy M12 * 1.25. you had the exact same size as the other box that you showed us with the orange and white lettering.
Going to try to do it while the head is on the bike with the gas tank in place do you think 5" in will give me that clearance? Thank you in advance.
Not sure about Clarence, hope you don’t have to take the head off
Thanks!

A tip I learned at Ford engine school If you have to do inserts with the head on the engine put the cylinder at bottom dead center of the compression stroke and fill the cylinder with foaming shaving cream ( Do NOT use the gel type) drill and tap then install the insert. then crank the engine over to blow the foam and any shavings out of the cylinder.
+fatboyfester Thats a very interesting tip--Thanks for watching
Thank you very much that sounds crazy but I'm going to use that method I have a 2005 Fatboy and I'm not taking the head off the engine and I'm not removing the gas tank, the shaving cream won't interfere with the oil Will everything be okay????
I love it if it works who's better than you I thank you in advance please reply. Just save my day
@@-MrRichBiker1967 I have only done it a couple of times and as far as I know it didn't cause any issues with the oil. If you're worried about the cylinder walls getting stripped of the oil film you could put a couple of squirts of oil in the cylinder and bumping it over before putting the spark plug back in.
Also depends on what you're repairing they can be more expensive than a new head for things like weed eaters and cheap Chinese brands
Oh and always always put anti seize on spark plugs especially on aluminum heads
Have you tried time sets? I always hated helicoils. Time sets are easy to use and work.
No, I have not
I'd advise removing the head rather than doing this in situ, like you say you don't want tap shavings in the cylinder or goodnight bore! great vid though. a true gent passing on knowledge. kind regards
Do you run 3 phase power to your ship to run all your machinery?
I own three phase converter’s
HeliCoils actually improve the strength of the threaded hole.
+pbooth001 Did not know.
+bottomlands In aircraft stuff, it's rare to to see a threaded hole in Aluminum without a factory installed Helicoil.
Anyone who's had to drill out a helicoil will vouch for that 😂😂 I wouldn't wish it on my arch nemesis 😜
That is so mistaken!
Autozone has better insert kits with a metal tool. It works in taper and gasket plugs. On cars with deep spark plug holes get a Time sert kit or better yet a Big sert kit. Get the one with the long tool.
Hey Pete, any progress on the Vespa?
+Andre Gross NONE!
long ago I worked at a shop where the owner used "KD" inserts.these were basically threaded tubes as the man hated helicoils for some reason(price?),anyway I wondered if you used or even heard of "KD" inserts and if so do you have an opinion?
No, I never heard of KD inserts
I have found if you apply an anti seizing compound to the threads each time the spark plug is out the aluminum threads will stay good..
+IslandSpudly I agree-I have 10 cans of it
How does the coil stay inside the threads?
