My Harmonic Balancer Went South :(

[el_kid_1]

Today my harmonic balancer wnet south and got starnded on the road. Where can a purchase a good harmonic balancer? I found this one at Jeg's, has anyone use it before?
It is going for $249.99 and it says that it is SFI certified. BTW, what does SFI stands for?

I thought with the 4.6Ls that the harmonic balancer was built into the crank pulley. I see you have a S/C. Most setups use the stock Ford crank pulley with S/C as it won't slow down the S/C like an aftermarket underdrive pulley would do. If that's the case, I'm sure you can find a used one as many of us have put on aftermarket pulleys with our N/A setups and have the stocker sitting in the garage.

I got a Romac harmonic balancer. It's supposed to be very good, but slightly smaller than the stocker. Houston Performance has the best price on them, as far as I know.

edit:Obviously I'm still half asleep, I missed the s/c part.I may have my original.If it is what you need, let me know and I will look for it.

The modulera engine is internally balanced and hences there is no external harmonic balancer. However, the crank pulley also serves as a dampner as it has a built-in rubber ring to further aborb any vbration.

My crank pulley for some reason is off the rubber ring! I think it is becuase it was old

I'm trying to get the crank pulley off, but I don't know how. When I wrench it, the crank pulley will rotate along and won't let me torque the bolt to loosen it. Is there any trick you guys know to remove the crank bolt?

It works! The bolt is off Thansk for the tip

Where can I get a good perfomance crank pulley for my car?

just get another stock one, yours is a freak accident, and a VERY rare occurance, i'm active on 4 large 4.6l tech boards and this is the first time i've heard of this.

What could have caused this?

 

[hotforstangs]

Get your self a good dampner, those elastic ones will eventually come apart, and you got lucky it didnt fly off and cause all kinds of damage, if you have the stock oil pump, you should really get a good dampner, to absorb the vibrations, other wise you could damage your oil pump gears and possibly trigger wheel, Im am using the FRPP damper, but Ive think the fluid filled damper would be the best to protect from engine damage. and with the kind of power you are pulling I wouldnt be suprised if that happened from the extra grip the supercharger puts on the belt causing the balancer to slip.

Would this be a good replacement for my stock balancer? Pioneer

Might consider BHJ. I've had good luck with those in the past.
