Not sure what engine you have/ Do you have the key lined up?

2014 C300 is M276 maybe?
In the photo it looks like the pulley directly behind the crankshaft pulley, which may be the water pump, is lined up.
If the mounting bolt is to torque spec and the key is in place, it should be in alignment.
Beyond that, I don’t have any shop procedures to share.

M276?

I would double check to make sure the key didnt lift up and its binding the pulley from going on more.

Need
Apologies for the late replies, been rebuilding this engine, so that wasnt the only thing, also can you share the website and program you guys use to figure out bolts and locations please?lol the reason I got in this mess was because of that, im assuming the flywheel is the part that i keep missing, should be held to tighten bolt all the way right? Wanna make sure, not trying to break and take apart again.thank you
