Crank pulley was created by JKemo35
So, crank pulley is buggered, I desperately need the car for work and what not can I just weld it back together, or does it need to be rubber bonded?

I believe you can get 1 piece ones. But getting it running true if you weld it will not be easy and it will kill belts if it wrong.

The rubber drive in the crankshaft pulley acts as a damper to stop vibration from the cylinder firing. Without this and if you hit the natural resonant frequency of one of the drive belts, the vibration could increase rapidly risking a snapped belt or worse excessive vibration in the crank which could cause problems with engine balance.
