Now what? Grind out the easy out? Weld a nut or bolt onto it? Thermite?

Buy a time machine, then go back and tell yourself not to.

EZ outs, in my admittedly limited experience, are for bolts that aren't stuck but which have lost their heads for some other reason. For stuff that's sheared and stuck, I'd recommend a shitload of heat and a counter-rotating drill bit. That doesn't help you now.

EDM is the fastest and easiest way to get it out. Further down the list is getting a punch and shattering it, then picking out the pieces with clay/plasticine on the end of a wire. Wear eye protection; not messing you about here, you need to be wearing impact rated eyewear (not snow goggles, spectacles, painter's glasses).

For those of you not in machining, playing electronic dance music will not get this bolt out, but Electrical Discharge Machining will.

I think alum is for when you have a ferrous object stuck in an aluminum object, which isn't the case here.

At this point I think you probably need to pull the head anyway, so may as well either do it on a bench or palm it off onto someone else to fix.

That truck isn't hitting anything because it's stranded in the suicide lane where it rolled to a stop when the suspension fell apart.

It's likely that most of the pistons are still attached to the crank and were therefore just flapping around in the diesel smoke breeze for a little while. I think the round things you saw falling out of the sky were likely rings and perhaps cylinder liners.

It's amazing he recovered from the very first deviation that was almost 90 degree off axis. The beefy rear tire deflected to the rim. That frame flex....

Hello friends!

Finishing up my degree at one of our military proving grounds here for a few more months. Sadly no pictures allowed but here is a good story.

I enjoy to participate in all kinds of test drives there but its a paperwork nightmare to prepare a "passenger ride" and the drivers usually take that drat serious... so after a while i asked around why that is so strictly governed.

Turns out that of course there were accidents leading to that.

The worst story i heard was a group of (former) officers paying the site a visit who got around to witness one of our MBTs drifting over a wet concrete circle at the end of one of our test tracks.

The concrete was wet because it was raining like hell and the officers took some shelter in our version of an MRAP that they used to get on the test track parked on the outside of the concrete roundabout.

one of the officers decided to go out and have a smoke with the Tank still running its circles over the conrete roundabout after each lap on the track and he decided to see "how close" he can get to the tank while it squeels its rubber blocked tracks over the concrete.

Long story short the Tank driver missed the apex as the rain increased and swung the rear end out a bit too far, squeezing the officers body in half between the 70 ton tank and the 10 ton MRAP.

Since then taking passengers and non test related personel to the tracks is a bit...firmer... regulated.






Also on the topic of Gearbox efficiency.

i saw 2 topics regarding the high efficieny of the 4th gear and why we dont do that on top gear.... let me answer that quickly.

there is a distinct difference between a 1:1 Gear ratio and a Direct gear. a direct gear is a thing that you only find in longitudinal transmissions (RWD) with concentric input and output shafts.
These gearboxes are of a 3 shaft design ("Vorgelegeschaltgetriebe" in German) with an Input, output and Countershaft. The Torque Flow usually goes from the Input to the Countershaft and from the Countershaft to the output shaft, with a fixed ration between the input and countershaft and the shifting gears between the countershaft and the output shaft.

these transmissions offer a Synchronized sleeve to be shifted over the input and output shaft, locking them together as a direct gear (4th Gear)

because the Torque flow does not go over any kind of gear meshing now (a straight gear mesh is up to 99% effective, helical gears lower depending on the angle, usually 98% in manual Transmissions) you increase the efficiency by 2-5 percent usually.

The reason we do not use these kind of direct gears for the highest gear is because what you make faster in the gearbox, you need to make slower in the final drive.

Due to the nature of the final drive, its ratio is directly coupled to its size (through the radius of the crown gear) and using a relatively fast 1:1 direct gear means you have to use a bigger crown gear in your differential which can worsen the efficiency, increase package size and the like.

aditionally, you will have to adress all the other gear combinations in your transmission too if you decide to change the final drive to have the top gear a direct gear.
