[s-cars] sheared crankshaft pulley

[desmo888 at comcast.net]

Alright, I'm sold. But where do I get a pulley for $40ish? I was quoted $95 at the dealer. I just did the tbelt but the front end of the car is still off so I will go back in and replace the pulley and bolt. 

BTW, does the Bentley say to replace the bolt?

You guys are kidding right?! 
Timing Belt with new gear and new bolt only, both are one time use IME/O. 
The bolt doesn't hold that gear in place, the key does, BTST failure. IME/O 
it has nothing to do with the install or the removal tools, it has to do with 
heat cycles, stress, and shear. The bolt is 12bucks and is a 1 time stretch 
bolt, the gear is 40 bucks and it's key is crappy pot steel that many times 
is hard to see the cracks. 

IME with S cars over the years, I've seen more failed keys than not. The 
*install* can cause it to fail just as easily, especially if reusing the old 
stretch bolt to factory torque. I throw away the gears regularly, but kept the 
one crank bolt that stretched itself almost to shear, and managed to get it 
out before it broke all together. 

I think anyone that's removed and re-installed a used crank gear is just 
lucky. The good news is that usually the key cracks below the keyline, and it 
usually stays in place that way until removed. I see it more on the S car 
than any other, but the problem dates back to the 5000.
