Help!! Crankshaft pulley question

[clicata]

Hey, I have a 2016 gle350. Changing oil today and looking over a few things and realized the cracks around this pulley?? I know it’s the crankshaft pulley but these cracks seem to be the rubber seal right? It’s no good?
Sorry just shocked- got this car 2 years ago next month and already needed to have the dealer replace the rear main seal and valve cover gaskets, finding more oil leak marks and then see this. Please tell me what it seems to be, and how it possibly happened thanks

You should take it to your Benz dealer and see if they could replace the pulley / harmonic balancer assembly as a “ goodwill “ repair. They are always worried about their customer satisfaction index.

I don't think that the rubber is broken, it looks to me like it is just the scraps from the mold. your harmonic balancer is basically a big weight with a ring of rubber around it and then a ring that goes on the outside of that called the pulley. The rubber should dampen. I would be very surprised if that is cracked at the age of your vehicle but of course I only really know Toyotas.

best of luck!
