Hey, I’m doing the same size bolt. I have the thread insert, just wondering what size drill bit you used and which tap to use?
Hey boss.Thanks for the upload. Iv got a 1993 ford f150 with a 5.0/302. one of the rocker arms stripped out. will this work on a steal head???
hey,
why do you tap that small thing off the heli coil?
greetz
@MsCraigslister
Or just disconnected the ingition oil from the engine, and crank the engine with the spark plug out. The compression will push the shavings out of the cylinder. You can do that if sand or something gets in there from removing the spark plug if you didnt blow air around the plug before you removed it
@cameramonkey2
Because stripped a bolt hole usually takes so much metal out from the hole you cant re-thread it the same size as it was before.. The helicoil you thread the whole to a bigger size so the coil will fit in, Then the original bolt goes into the coil.
Instead of getting an “installation tool” couldn’t you just file or grind a bolt’s end to do the same thing? I’m talking as an alternative to buying the tool set and it’s only for a one time, one size job.
Great video, how much different is the Time Sert device then this, does it do the same job and as effectively
Great video. Easy to follow. Makes it look really simple. Thanks
Great video. I want use to repair a tripod thread. Where I can buy Heli-Coil brand thread repair insert. ? Thanks for your help
Thanks for this video.
I pulled the threads on the final drive housing of a shaft drive bike, don’t feel like paying $300 for a new one. Plus I’ve read that helicoils are stronger than the original aluminum which is good. The spec is 90Nm which I thought was too much for aluminum in the first place
@3SGEpower i never heard that shaving cream. but i left a comment, dip drill bit in wheel bearing grease. worked good for me. I like your comment thanks.
Good video, but as i remember you turn the tap a little then turn it back which cleans the threads. If your doing a spark plug hole with the head is still installed, make sure the piston is all the way at the bottom. use grease on the drill bit and as you drill most of the metal shavings will stay on the drill bit.just dip the end of the drill bit in the grease. too clean the metal out of cylinder use a solvent like carb cleaner and very small magnet that is made in the tool. aluminum burns up,
How do you do the sizing for the drill?
@Mathewmartialart – I have no idea why he hit it. I use needlenose pliers to grab it and break it off, pulling it out at the same time. This guy should go back to auto-shop!
Good video, heard it mentioned a few times and never understood it.
If I were to use this on an exhaust manifold/head, and it was torqued up to about 8nm, would these helicoils be strong enough?
Very educational. Thanks
@ttcautotech anything you really need strong clamping force(like a head bolt). a time sert is better for that imo. helicoil gets the job done for most things though
@mrmaxstorey Back in mechanic school, the trick they gave us to catch shavings when rethreading spark plug holes in place was to put the cylinder at bottom dead center compression and to fill it with shaving cream, rethread the hole and then just turn the engine over by hand, that’ll push the shaving cream out the plug hole with the metal shavings.
@pbassred in this case you don’t want the chips falling in the Engine best is to cover the tap in greese and not wind back
will this have to same ‘strength’ as the oringinal thread before it was cross threaded?
I have a caliper mounting bolt and im worried the insert will not be safe enough to work.
you should put some oil to make the job easier….
This sure was helpful, you’re a good teacher sir ! Thanks a lot !
ok, so how do you solve the issue when the bolt is missing the and bolt next to it ISNT the same size? and how do you get the thing that breakes off if it doesnt come out by blowing it
@BuickDoc Time Serts are supposed to be stronger. They’re both quite reliable though, I have yet to see either one of them fail but I’m sure they each have. Personally I like Helicoil’s much more.
@BuickDoc Not sure which one is better as I’ve not used the timeserts very many times. The Helicoils have worked for everything I’ve used and so have the timeserts. The timeserts I have used have all been soild inserts for spark plug holes. They seem like they might have an advantage.
