I'm surprised it didn't take his head completely off. Damn, when it's your time.....there's just no stopping it.

Damn! Nice to see people spring into action to help the injured party for once. Shame they couldn't do anything, still good to see people try to help for a change.
I don't like seeing hardworking people go out like that.
At least it was quick I guess.

Damn! Too bad there isn´t a closeup.

It was a flywheel separation: I have been present when a flywheel explodes, luckily when that flywheel went, the axle stopped parts from going through the cabin (transverse engine). Parts of the flywheel went through: The bell housing, the hood and the steel roof. It also took a chunk out of the concrete below the car the size of a dinner plate.

Yes, flywheels have ring gears, however the body of the flywheel is cast iron, while the ring gear is made of machined steel which is then heated and pressed onto the flywheel. When the flywheel shatters like that, the ring gear separates and flys off till it hits something. In our situation the ring gear hit the axle and it “straightened” it and it looked like a rollercoaster track.

The issue with our failure (and I bet here). Is that they machined the flywheel thinner to reduce mass. By reducing mass, the engine can transfer power to the transmission faster without having to use that energy to spin up a heavy flywheel. It is a cheap alternative to buying a chromoly flywheel.

That red is not oxidation, it is paint overspray. Probably from when they painted the block.

There is no “bullshit” here. They were free-reving the engine, which puts little stress on the engine internals (rods, crank, pistons). But puts a ton of stress on the flywheel. The area the debris came from is the area to the back of the engine (where the flywheel is)

This was a bad situation and it’s the reason I stopped working on any performance car with a lightened, flywheel.

Did it pass the MOT?

Man, I guess when its you're time, it's your fucking time.

There is no way to inspect the flywheel for any annual inspection.

The flywheel is bolted to the crankshaft with 6-10 bolts near the center. The clutch is then bolted to the flywheel. Then the transmission is installed with the bell housing of the transmission surrounding the clutch/flywheel assembly, fully encasing it.

Some cars have small holes in either the bell housing or on the engine side for accessing bolts, but without a fiber optic inspection camera, you cannot access much of the flywheel, and even with that camera you cannot access enough to make it worth the effort

Hey pencil neck. Noone referred to the red paint as bullshit. In fact noone mentioned it. What was mentioned was the oxidisation in the cracks where the breaks are. Sure it doesnt take long to oxidise fresh cast but im sure evidence wouldnt be lying around in water for days in a clean car shop.
Paint...pfffffffft

Also that car could have been auto trans and that flywheel pic is of a manual clutch flywheel. Its not a torque converter drive plate.
That pic is probably some junk yard BULLSHIT someone has used to show a piece of engobe for the news story so retards can sort of understand.
