I have never thought about using helicoils in them. I usually use JBWeld to build up the existing threads and then screw a plastic type screw in them coated with grease, so it won’t stick to the JBWeld. I screw it in loosly and remove it after the JBWeld starts to set. The next day, I will screw the screw into the new threads that I made with JBWeld. I do not tighten it fully for several days to allow the JBWeld to fully harden. I clean the original hole throughly with break cleaner and coat the remaining threads with a tooth pick with a little JBWeld on it. I am just trying to build up the threads before I screw the grease coated threads in the hole. You have to use a machine bolt in a helicoil repaired hole instead of a P screw. Most Stihl screws are P5 screws.
i isually cut small strips from a small nylon cable tie the length of the hole plus a lulittle more outside the hole and reinstall the screw...never had one fail and a lot cheaper and less work...
Had this happen before ended up drilling all the way thru the plastic grinding it flat on the back and ran a bolt thru with a nut on the back still holding strong
Home depot sells some rippled heavy duty aluminum foil type stuff you cut with scissors ..then u stick in hole and then you stick your screw in and it grips to side's
I'm an old Helicoil guy, got a big drawer full of 'em. I've even got that 5x.80. The screw being replaced was a self-tapping screw, meant to go into a smooth hole in a molding made of old milk jugs and hopefully never taken off. Why did it go bad? It's just holding a clamshell assembly together with screws either side. Was this for a demonstration purpose? That's fine. Was the cover removed and this came as a consequence? Whew, so many questions. When I saw the first video, with the comically small wire, (a stupid fix in any event), I wondered why nobody stumbled on what seemed to me to be the obvious solution and one I've used many times on small engine equipment with this issue. Take that screw, hold it in a pair of pliers and flatten it with a ball pein hammer on the anvil of your vise until it's about a millimeter wider. Maybe more. Whatever. Slather it with your fav plastic glue, (yes it will come out later), and after 27 seconds of work it's done. A Helicoil here is kind of overkill, but actually, if I was in the right mood, I'd do it. But dude, pull the cover. Do it right. I'd never drilled that 1/4" hole. I've seen an Echo blower with a 1/2" drywall screw doing this job. Love your videos, but just like with Steve, sometimes
Yah, seemed silly to wallow out the other side of the cover when you aren't inserting the helicoil there. If you are going to go to the bother of "doing it right" then do it right.
Great video, thanks for the knowledge. I have a similar situation however the hole is all the way through. Can I still use a Helicoil or will I just screw it right out when I go to screw my screw in. Let me know if you can help me out. Thanks so much and hope you are having a great day.
BMW Dealership screwed my moms car up. overfilled it many times becvause all the gaskets were leaking like a siv and stripped her drain bolt. She has a plastic oil pan and a plastic bolt. They wont own up and want her to pay for new oil pan. gonna try this and replace w a metal drain plug. Do you think i would have any problems w a metal drain plug in a plastic oil pan? Thanks. Just trying to find a cheap fix.
I like to use thread lock when putting in Hel/coils. Could you send me the model number on your pressure/vacuum test kit? I would greatly appreciate it.

Used them in heads blocks etc. but never thought about plastic, great repair and tip thanks.

How about using JB Weld?
Great video. I’m about to try this on some wallowed out threads on my swimming pool valve
Great demo, easy to follow. Thanks sir!!
Thanks

What kind of plastic glue do you recommend?
Great video Thank you
Good video I need to do that on my blower.
Great video, thanks for the knowledge.

Could you use red Loctite or some ca glue to lock the helicoil into the plastic?
I wouldn’t
@@THEMOWERMEDIC1 Ok thanks!

Does the kit come with a drill motor or do I have to buy that separately?

LMAO Did this guy just grunt on that little screw? way to over sell it.
Did you ever try LOCTITE FORM A THREAD ? it worked for me ....
Yeah it’s just jb weld
In a pinch I used piece of Toothpick
Weed eater line works great too in a pinch
Lots of "that's what she said!" available references in this tutorial.
No way😂
Since you are already using a different screw, just make this whole process easier and just use a bigger screw!
I did ! You didn’t pay any attention
@@THEMOWERMEDIC1 with out a helicoil....
@@THEMOWERMEDIC1 yeah, in this situation, there is no point to helicoil-ing it, just put a bigger screw in (with no coil) and say goodbye
@@titansrba3339 No thanks. I’m not going to risk busting the housing by cramming a bigger screw in the hole.
Just use a bigger screw. Otherwise I stopped using helicoils in the mid 70s. Used timeserts my whole career and as a shop owner.
another quick fix is loctite formathread
Well done, the right way
Just epoxy the two halves together and refuse to work on it again
👌 ok
Kind of defeats having repeat business when you don’t want to work on your own repair !
@@hatteraslabuf it's a joke
@@THEMOWERMEDIC1 just a joke but it's about what half these repair guys in my area do
Kurt Knisel. 🤣😂🤣. OK, I laughed . . . you feel better, now?
Wouldn’t been nice to see you break the tang off, other than that it was very informative
it just breaks off.
I would have put a couple of small pieces of copper wire in it and put the screw back in. All your doing is holding a cover on.
I don’t think it will work but I’ll try
