Loctite "Freeze & Release" - Does It Work?

[Vincent]

I've got a couple of exhaust studs to try and get out. I've tried everything in my arsenal but they're not budging. Is it worth trying "Freeze & Release"? Anyone found it worked?

TIA, here's the offending stud:-

I have had some success with it, usually by heating the whole area with a blowtorch and then using the freezing spray on the offending bolt. Bear in mind you need to use quite a lot of the stuff to make the bolt really cold, a short spray will just give you a bit of penetrating oil but not much coldness.

Heat, cold, penetrating oil and decent mole grips should get that stud out. Hard to see in the picture, has it sheared off on the threads?

[G]

Can do.

I would go for a proper penetrating fluid like plusgas, heat the outside, then a normal freezer spray on the stud.

If the thread is still usable (it doesn't look it), I'd try and get two nuts on their as a lock nut.

[Vincent]

It sheered off at the nut - I've used loads of PlusGas for the last few days and tried two nuts but there's not enough thread to support them. I've filed two flats to get the end of the mole grips on but, for the moles to work best, I find you need to use the round part of the jaws which is too big for the stud - when I use the flat part, they just open up slightly and won't grip. I've been heating it with a propane torch but the stud isn't getting red hot. Sounds like the freeze spray might be worth a go then.
I'd like to try the "welded nut" method but don't know where I could get anyone to weld it on for me.

Gawd I hate these studs

Where's it best to heat? I've always heated the stud but some say to heat the surrounding ally

These drill out guides look good, this ones for a Harley, I wonder if anyone makes them for my bike?

I seem to remember a thread a while back about using the exhaust clamp to do the same thing but the above one slots nicely into the exhaust port for a better fit.

Another good "drilling" thread from the TL forum:-

Heat the ally, freeze the stud. Ally expands and stud shrinks back to size.

Anyone use one of these? Any good? I like the look of the bottom one

Above pictures look like an interesting route to take Keep that one in the back of my mind.

Time to invest in the welder you've always wanted to buy?

I've used the bottom one with great results.

What's best about the bottom one is all the force is acting in a circular motion around the stud, rather than at a moment from it (top one). So that way you have the least possible chance of it shearing off. Also, it will grip the whole length of the stud so it has maximum chance of coming out. You've got loads of stud you can see there, you should be able to get that out!

Don't go near a drill until you've tried a proper stud extractor as 9 times out of 10, with the proper method you'll manage to get the stud out using the stud extractor, and fuck it up using a drill.

Heat the surrounding area that's holding the stud in, either use a syringe filled with water or the spray that you've said sounds good on the stud. You want to heat the ally to make it expand and release the grip on the stud, and cool the stud to do the opposite to the stud. Ally has a higher thermal expansion rate that steel so get it all nice and hot around the stud. Try not to get any water or spray onto the ally ( which is why the syringe method works well as its easy to control where it goes).

There are some videos of the stud extractors being used on YouTube if you're not convinced, so have a look on there

I have a set of the stud extractors in the middle pic - they work a treat. I've also used freeze and release - heat the surrounding area and give the stud a good blast then stick the stud extractor on quickly and all should be good.

[Vincent]

Aye...it's the bottom one I like the look of. 'Just been up to the nearest tool place, they have a Sealey one like that but eBay have Neilsen ones at half the price.....and you can get a box of four of the middle ones for just £15.
It's going to have to wait untill next weekend is all - give me chance to get the studs and gaskets and clean the old downpipes up a bit though.

Need some more flat jawed Mole's too.

Those oil pipes on the VFR are a bit of a PITA - what with them rusting away........not easy to replicate either.

Thanks for the help

Offending oil pipes, (exhaust leak ringed):-

Consider filing it down a little to a more triangular shape too, to let the extractor get a better grip.

It may be worth making a shield using a washer or similar to prevent the spray cooling the surrounding area too much - and the heat getting the stud too much.

[Vincent]

[Raffles]

As far as the stud extractors are concerned, I reckon that the most suitable one to use on that stud would be the first one pictured. It will apply a grip to the only remaining intact part of the stud.
The type of extractor featured in the second picture works on a cam principle which forces 3 jaws parallel against the stud. They will attempt to grip approx 12-15 mm of the stud but as most of that amount of the stud appears to be shagged and stepped then it won't effectively grip any of it.
I'm not familiar with the third type of extractor but I suspect that it works on a similar parallel jaw principle to the second one and as such will be unsuitable.
BTW You have mail.

The 'jaws' on the third one stick out for smaller studs - it works like a drill chuck (though left handed), but has a wider aperture so they protrude more.

[Tiff]

It looks like its a 10mm stud with an 8mm thread? If it is, the stud extractor will only grip on the part that is the size of the extractor. Can you run a die nut up the larger part, and use a larger nut on there, and a smaller nut with a washer to lock them together? Then you are putting the pressure on the larger diameter part. A good smack perfectly straight on with a hammer whilst putting anti clockwise pressure on works wonders too.

I RECKON it will.
You should be able to get a spec of minimum stud size before you order. But mine went pretty small I believe.

[Vincent]

the smallest I can find for those types is 6mm, which is what the stud was before I filed it away - I thought it may go smaller because of the way it works.

I'm going to pick a "chuck" type extractor up in the morning - I'm not holding my breath though and the drill's waiting in the wings

Sheeeee-at The new extractor didn't fit but I made a collar with a slit down the side to go over the stud - it did grip....but bust the stud in half. So I'm left with about 6mm protruding. Next step is to get another set of mole grips with flat jaws, if that doesn't work, it's out with the drill
