Crank Pully Anomaly
 

Has anyone ever seen a crank pully separate? It appears that the grooved portion of my Crank pully is sliding forward away from the engine. My alternator is now running on the inside portion of the grooves and my A/C is flapping in the breeze but still turning the water pump?

Has anyone had this happen?

I'll be having it "rollbacked" to a dealer today. With my luck the sucker would fly off and grenade the engine compartment. I'm glad I looked when the A/C quit!

Mine separated, drove a few hundred miles with pretty minimal symptoms:

Well, she's been towed. The Subaru folks once saw a legacy do the same thing. The legacy however, had the pully assembly completely separate. It took out an alternator and the timing belts and timing belt cover.

I'm glad I looked!!

This is a tech question, and therefore belongs in the tech forum. Please post in the appropriate forums. :)

This is an observance... I thought it would more Likely be seen here by high mileage SVX owners than in a tech forum. If this happens, unnoticed, you could end up trashing the front end of your engine.

It's more common than you might think. Fortunately it has not happened to mine yet but I don't doubt that it WILL now that I've said this.

The pulley usually slides back and grinds into the timing belt cover.

Like mine did. Do I need to go in deeper than the timing cover to fix it?

I don't know if the pulley would go as far as to start chewing on the timing belt or not. Hopefully people find this problem before that happens.

Mine Seperated completely about 4 weeks ago, went ahead and bought the UnderDrive from Dayle, works GREAT. I wouldn't put off getting it replaced, it will kill your alternator, power steering can go out at any given time, and your ABS can as well. Just my $.50
