I have a problem with my car honda genio 95. The crank shaft was broken, at the places near spy. For information In a month Aug 12 I has a change pulley n all fan belt. Do you now, why that's problem hppen? Tks before

 

What pulley was put on it?

did they over tighten the crank bolt and weaken the thread?

 

What exactly happened to the crank?

If it's damaged/broken you don't have many choices.
