What caused this crankshaft to break ?

OM603.x (3.0&240k)
Crank broken at snout.
Is a crankshaft damper commonly used?

This picture tells me nothing, need to see the crankshaft.

Also I'll counter your " -“Never trust a mechanic who drives new cars. They're either charging too much money for their work, or they can't keep an old car running - maybe both.”

Why do you think that a mechanic wants to work on their own car after working on them all day? ( This isn't to say a mechanic doesn't have a disposable daily driver in the mix. )

What makes you think that they are not entitled to be paid for their skills?

If you think this is such a lucrative business, why are you not running a shop as your sole source of income?

Gotcha. I am away from my car all parts with it now, but you're saying Im looking at only 2 pieces here rather than 3? The harmonic balancer and pulley only...
Just wanted to verify that the part on left where pulley bolts stop isnt apart of the crankshaft snout.

Those are all good rhetorical questions, thank you.

S-K C:

When the photo in this thread (post #1) is matched with those in your other thread on this "problem", it appears that the nose of the crankshaft is still in the engine, firmly attached to the rest of the shaft. So what is the cause for alarm? Where is the broken piece of the crankshaft? If it is in fact a separate piece, you can make your case by showing it separately.

You're absolutely right.

In photo 1 I thought the sleeve of the harmonic balancer was actually apart of the crank because the only crank I ever had to mess with (om314) had that assembly at the end of the crank rather than the pulley hub like in photo 1. I would have solved this much earlier if I was at the car but all I have to go off of are pictures until Tuesday evening. Right now I just need to file down the slot for the pin and purchase a new lockpin and crank bolt.

Are the internal threads of the crank in good enough shape to hold the 300Nm or whatever torque of the pulley flange bolt?

So, let me get this straight, you berate a mechanic that drives a new car but you can even fix your own? How can you justify this? You didn't answer my questions is post 2.

Why the small font in your sig? Here let me zoom in.
