I couldn't find 3D helicoils for my threads so I ended up buying 3x 1D helicoils and put 3 of them in a single hole. Worked out great. But only time will tell if they hold.
Hi there. My crossmember frame hole is strips out the bolt is m12/1.25 I couldn’t tighten it up it keeps spinning so what size of the heicoil repair kit do I need to? Thanks
How do you distinguish if your all the way down or the threads just aren’t cutting smooth? I guess you can always put a piece of tape on the tap but is it easily to tell the difference?
How do you make sure you're drilling 90° to the deck surface? Having to do this for a strocked 421 sbc and worried about not being straight and damaging a sleeve
You can take a tube the the bit fits into nicely and use it as a guide. Welding some kinda plate to it helps too incase your really new to cordless drills. If at all possible use bronze and oil but normally oil does it fine even if it's in steel.
The hole is already there so you just let the bit follow the hole. The hole is almost the size of the bit when the threads are gone. Don't use a helicoil for a head bolt though.
I had to drill some holes for my main bolts. I even had the main caps on to use them as guides so I drill nice and perpendicular. What I found out was that if you have even a fairly small amount of wiggle room, you can very easily end up drilling holes slight off to one side. And with a nice sharp drill bit you can drill way off to one side without noticing it untill it is too late. So having some sort of solid rig to keep your drill bit nice and perpendicular is a must. Don't go do this stuff hastily. You will curse and regret.
@Silent Sniper I actually sold it before fixing it. I don't have my own garage so I couldn't keep it sitting in there's. I ran out of money to dump into it too.
Hey bro did u fix it ? I’m fixing my head gaskets and the number 8 head bolt thread stripped I see there’s a kit for like 499 form ns300 what kit should I buy ? And we’re u able to fix this ? I have the same penstar engine
Mate great video 🫡 I need ur advice, after I replaced rocker cover gasket on my ford Barra green top I snap one of the bolts inside the head 🤦♂️ the bolt size it’s 8mm , what should I do ? Thanks Matt
@@Conorsev Thank u , But what happens is the bolt was deep not much just 3cm in u can see the tip and the broken cut not straight and it’s so hard to get the point and do drill and I eat a bit from the head ☺️🤦♂️
@@danielpelaez9978 I used helicoils on my engines main bolt threads and they work great. Finding solid inserts that are right size is almost impossible and when they are available, they are quite expensive. Not to mention that solid inserts need way more material to be drilled out and not all engine blocks have enough material.
Be sure to be SQUARE!!!! I goofed & got a degree or two off & now I need to get a welder to fill the holes & then I got a drill press that has a foot to bolt to the deck to keep my drill bit square this time!!!!!!!! BE CAREFUL!!!!
Yeah, don't go fucking around. Even if you think the drill bit is going to follow existing hole, usually it's not going to and you end up easily couple of degrees off. You either need some good solid rig for hand drill or a good drill press. Cheap chinese drill presses can easily have enough play in them to end up with holes that are few degrees off even when you start straight in the middle of the existing hole and everything looks perpendicular. Not as easy as it looks.
Excellent explanation and video, thank you!

Did you weld on the tool like in the video?

You should have put high temp lock tight on the outside of heli coil, and you need to break tang off, and remove from hole

Great work done right proper 👍 thanks for the lesson , I need to do that tomorrow on a 1915 model t
This is a very useful video
Lifesaver, putting together an 06 CBR 1000RR and hoping this will be my fix. 🙏
I've got a 99 cbr 900rr. Did this work for your bike?

Any suggestions for doing this on the lower engine block where the header goes
Excellent video, super helpful,
What kind of bolt is that you used. Pretty cool.

Damn wish there was a part number for the kit
Same problem,but for the threads of bolt wich fix ignition coil,on megane 2😢
Awesome video brother thankyou, guess it’s my turn to give it a crack now haha
Mate great video 🫡

Thanks

Once it's broken the tension should be off it so wont need much force to undo. An easy out should get it

What's the torque spec on the head bolts?
Can you please do my kia Sedona? I can't find any mechanic that will do this
Threaded inserts for head bolts? They aren't even solid inserts. Wild stuff.
What should u use then ?

Where did you get the 3d coils from
Local tool shop
Kinda hard to find
What's the name of the local tool shop?
M&G industrial
I'm curious how this held up a few years later
@@chucksnothereman still going
@@Conorsev great, stripped mine on the weekend.
why did you start front wheel drive drifting? idk why ive never asked lmao
Just liked my car and wanted to go drive with my friends
This helped thank you
Fuckin awesome explanation and demonstration. Best I’ve seen tbh
Just bought a kitten I got to find my extenders
Thank you!!!
Nifty
These will never hold long 😂
@@B-cm80gc did this fix years ago. Litaraly just did a track day in the car like 3 days ago. Still going strong
person may say use time sert instead of holicoil
th-cam.com/video/LpDduCVUy6w/w-d-xo.html
I would agree with this
At least use a solid insert like time sert but no way would you ever use a helicoil for a head bolt
i put a=2 instead of 10 for a in M=F*r=m*a*r and stripped my 3/4 head studs😭
