    I've searched around and there is a surprisingly few number of photos of mechanical gearbox shell failure aka "v2 cracking". There are way more photos showing up on how to properly radius or do other modifications to mitigate it. In order to better understand differences between each companies' particular casting alloy and the effect of different styles of gearbox design (usually combined attributes) I am interested in seeing if there is a trend particular to companies' designs in terms of specifically how they fail.

    I understand that this is going to be majority v2 type gearboxes, which is fine. I personally am mostly interested in v2 and v3 anyway. However, photos of any version gearbox with any type of catastrophic mechanical failure is welcome to demonstrate failure methods.

    If possible, please include the brand of gearbox if that information is available. I'll kick off the thread with some that I found around the web. There is quite a few photos but few of same brand, I am interested in getting as many data points as possible.

    Second unknown looks like a tm since it has the two piece hop up and the color of the shell.

    The front of the gearbox cracked, but only on half of the shell. (At least for now)
