Car was making noise found belt tensioner was bad. Pulled it off replaced it started installing the new belt and when I touched my crank pulley it fell off in my hand. So if anyone has a crank pulley for a sc300 and your in the tampa bay area let me know thanks.

 

Seems to be a common problem on these cars. you can by a new harmonic balancer for your car for about 86$ online. For SC300's aftermarket/ supra, but I have to pay almost 300$ for new for my SC400. NOT FAIR!

 

This is a common issue, they seem to shell themselves after about 120k, I replaced my 2nd one at 240k. I recommend you buying it new because its going to happen sooner or later so you might as well push it out as far as possible with a fresh one, anything else is a time bomb with an unknown fuse..
