[@hanshogqvist7927]

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. :-)

Helicoil not healicoil Aluminium not aluminium. Antiques are 100 years old or older.

[@bluedevil0072]

I use Red Loctite when installing Helicoils. That way they stay in place when removing bolts or plugs.

[@larrylewinski3086]

That's a great idea

[@ErnieNoa3]

Thanks for showing this. I have always wondered how the Helicoil worked.

[@robrussell5911]

[@shawnmrfixitlee6478]

thumbs up , The newer Heli sets have a cheap plastic tool to install the coil ! I like those vintage type tools better ..

[@mrpete222]

+ShawnMrFixit Lee Thanks for watching

[@Satchmoeddie]

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.

[@cemx86]

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!

[@mrpete222]

+cemx86 Thanks for watching--well noted on the taps

[@sekemagentles338]

I need a heli coil done ASAP. call me 215-475-0255

[@bikingmnviking3801]

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!)

[@Satchmoeddie]

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.

[@dictare]

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!

[@mrpete222]

+dictare NOT GOOD!

[@bikingmnviking3801]

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.

[@EtheB1]

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.

[@mrpete222]

+marv w Thanks for watching---good points

[@-MrRichBiker1967]

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

[@WAVETUBE84]

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]

+WAVETUBE84 Thanks for watching--good idea on the clean out

[@WAVETUBE84]

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.

[@mrpete222]

+WAVETUBE84 Thats a good idea

[@dean-gm1lg]

Make sure both valves are closed and you would be surprised what a good vacuum cleaner with an adapted end fitting will suck out

[@donens9310]

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?

[@patsullivan9399]

It's a bad feeling when your doing this on an assembled motor, and you break the tang, take the pliers out of the hole... but no tang. Especially if it's a motorcycle drain plug and you have to split the cases to find that fricken tang.

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.

[@mrpete222]

Not sure about Clarence, hope you don’t have to take the head off

[@godfreypoon5148]

[@PennLineProductions]

Maybe I'm un-informed but why dose an antique engine and spark plug use metric sizes? Were the spark plugs or the engine made in a country that uses metric? (i.e. not the US)

[@mrpete222]

+PennLineProductions They are all metric threads

[@rwbishop]

Just my opinion... but I'm not crazy about Clinton leaving all those exposed threads in the combustion chamber. Yes I know it's a low compression engine, and they're not likely a big pre-ignition source, but still, it's not a good design practice; not to mention sloppy looking. I've seen much the same in other engines as well...

[@mrpete222]

+rwbishop You make some good points-Thanks for watching

[@Justin-bb2hj]

I can't stress this enough TRY A SPARK PLUG THREAD CHASER BEFORE DOING THIS! Start the tap from the back of the head if possible the threads are normally better on that end

[@carverindian]

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

[@MIGASHOORAY]

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.

[@CreepyMonkeyHeadGame]

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

[@matttrotta57]

I can't afford to have Helicoils sitting around for "just in case" situations because they are so darn expensive. Why are they I mean look at it it's just a little bitty thing.

[@mrpete222]

+Matt Trotta yes-they are costly

[@jeremyzamora2875]

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

[@robertmccully2792]

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.

[@GROWWHEELS]

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.

[@paulaleksinko9039]

I didn't know that it was a difference between Cutting oil depending if it is aluminum or steel, Thanks for the tip Mr Pete..

[@BedsitBob]

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.

[@AdammP]

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

[@Fourcycle]

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.

[@mrpete222]

+Fourcycle Its not the correct plug- Thanks for watching!

[@georgehoffman5665]

in the days of yore if you didn't have a helicoil you run a tap through the offending hole to clean up the threads then wrapped the spark plug threads or what ever culprit was to blame with copper wire and screw it in. it worked almost all the time.

[@user-ks5ff]

Maybe where the idea came from?

[@BedsitBob]

Or, maybe you could just thread for the next size spark plug, and use one of them instead.

[@peteb2]

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)....

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.

[@mrpete222]

No, I never heard of KD inserts

[@SeanBZA]

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.

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.
