damper pulley

got a 1999 taurus 3.0 DOHC and the shaft behind the harmonic balance pulley broke. removed the bracket and harmonic pulley and the shaft is the only thing left. Are the thread for the shaft going into the damper pulley left or right? trying right thread (as I was told) with a 3/4 breaker bar and a 1/2 impact wrench counterclock wise and getting nothing.

Re: damper pulley

If you're trying to take the bolt out of the front of the crankshaft, on the 4v engine, it's left hand thread. What shaft are you talking about?

Re: damper pulley

The only shaft behind the harmonic pulley is the crankshaft. You telling us your crankshaft broke? If your crankshaft broke then you're effed and need to buy another car. And there's no bracket there either (that I know of.)

I'm gonna guess you've just got your terms mixed up.

Anychance you mean the belt tensioner pulley?

Re: damper pulley

Thanks so much! Your diagram was perfect! I got bad info from someone else and as your diagram shows, the crank pulley attaches to the damper with left threads. Will try again tommorrow!

Thanks again!
