Vibrators

thats just air impact

u need the inductor then heat produced but elctro magnetic field

Yes, they look like great pieces of equipment and perhaps some day I'll get one. I don't think I do enough work on small stuff to easily justify one though.

No I dont have any detail, hence the original post .. there was no mention of an air hammer or anything violent.

The service was a man in a van turning up to avoid snapping the offending potentially stuck item. My immediate thought was ultrasonic but that is just my mind not any real information.

On the basis that the breaking the stuck item meant engine out / body off to fix, the high cost of this mobile service was deemed worth it.

I was hoping someone here might have heard of it as it sounds interesting.

Would be interesting if ever you do find the answer you want.
I know there are 'mans in vans' who can remove snapped glow plugs when people have had a go at DIY removal, no idea how they manage it without removing the head but I suppose it's in their interests to keep very quiet about their methods.

that seems to fit the scant description, thank you.

I need to have a close look at that now

For sure, and its not something I'd even consider commercially copying but a diy 'similar' just seems like an interesting project

I have used this similar principal for years in fact did it yesterday on caliper sliders that someone had put in with a nut gun!!¬, put cap head driver or torx bit in bolt head, put loosening pressure on with a breaker bar, and hit end of the BB knuckle with copper hammer directly in line with the bolt works most times, transit front wheel bearings are particularly bad, for shearing/ rounding off.
for normal bolts what you would need is a very shallow hex socket with a blind hole but that will not work for heater plugs unless you cut off the excess.

The vibro tool from Snap On I showed uses deep impact sockets but the hex cutout is very shallow. This means it goes far enough onto the nut/glow plug etc to give grip to turn it but stops short of the end so that the impact goes into the fastener.

Yes that is exactly what I was trying to explain but heater plugs would have to be cut off at the hex to allow this to happen.

In which case if doing a few the cost of the specially made sockets is probably well worth it I'd think, to save trying to cut them down in tight engine bays.
