Pulley problem

[Mustang Matt]

I took car out today to see that the battery light was on and car had no power. I got car home charged the battery and started it up with the battery light still on. I looked under the hood as the motor was running and none of the pullies were moving? I can turn the belt and all the pullies with no problem with the motor off! My guess is the crank pulley has broken or a bolt is missing. Any one have this problem? Is there suppose to be a bolt in the center of the lower pulley? Need Help

ummmm... in the center of the lower pulley there should be a bolt. It sounds like you may have rounded off the tab on the snout of the crank. I sure hope not, take some pics.

There is a hex bolt in the center of the lower supercharger pulley. Any one ever have the stock pulley off the car? What could have broken?

sounds like your ripped the key way off the crankshaft, Looks like its time for a new motor

out of curiosity, you do know there are 2 belts on the car correct? Try taking the lower crankshaft pulley off and inspect it. I'm sure there's at least 10 stock lower pulleys on here that you could compare it too. Try taking some pics and let us know.

The pulley that I'm talking about is the outter crank pulley for the supercharger. This pulley runs the super charger and the alternator. the center hex bolt that attaches to the the crank just spins.

A new motor ha ha ha... I won't be going through that again. I think it's a minor fix. I have to call Ford tomorrow to see if they will work on it..

The way you explan things are very hard to understand but from what your telling me, it soulds like you busted the outer pulley. I have a extra one laying around if you want it, it's yours. The center hex is a 14mm. Just remember they are reverse threads (lefty tighty, righty loosy ). Need any help with anything shot me a PM, Im always willing to lend another cobra owner a hand :headbang: Ive only seen this once or twice on Mfords.
