On the way back from getting parts for my mark lost some accessories, then bang clang boom. As i look in the rearview the crank pulley rolls out. It made it home about a mile in a torrential down pour. Got in the other car and grabbed the pulley. Whats the best economical replacement part? Im not planning to keep the car much longer . Id like to post a few pics, but How can i post up some pics without an image host?

if the bolts just fell out and you didnt ruin the pully you can prob get new bolts , if the harmonic balancer broke the car prob would not run

OUCH.....:eek:

I saw the first picture and thought.... That isn't too bad.....

Then I saw the last few pictures.....

Looks like you will have to remove the HB to get those 4 broken bolts out....

Im going to try to straighten the pulley, remove the balancer and tap it out and use some lager bolts. theres a small crack on the lip of the balancer, is that something to worry about?

99% sure the balancer is bad and is the primary reason for the pully failure. Is the bolt that holds the balancer onto the crankshaft still there ? The head of the bolt usually breaks off when the balancer fails.

I'm with Dave. Besides Never ever remove a stock balancer frm a SC and try to reuse it. The end result could be a crank needed.

Not true i've done it on several occasions and it is purely a myth,mine works just fine.
Don't reuse that bent pulley,you'll never get it back to normal.

I've reused the original HB from Black Betty on three different SCs with no problems.....

However, I have never had a pulley failure like yours....:rolleyes:

I would replace the balancer, just to be safe.....:D

Reinstalling an OEM balancer on the same motor it was removed from (like when swapping cams) has not been a problem for me either. However, installing a perfectly good used balancer onto another motor almost always results in a balancer failure within a few months.

Some of that may have to do with the location of balance pins from one motor to the next, but I think the bigger problem is with the balancer's aluminum hub conforming to the shape size of the original crank snout and not fitting as tight as it should on another crank.

If you get lucky and the balancer was removed from a crankshaft snout that was smaller (low side of tolerance) than the motor it was transferred to (high side of tolerance) and the balance pins are arranged the same or absent on both motors, it could run for years without a problem.

I can agree with that....:D

One other thing that needs attention is the way the used balancer was removed and reinstalled.....

Using the proper tools to remove and reinstall help out a bunch.....

If the HB gets crooked when removing or reinstalling then it is finished and should be used as a doorstop.....:p

I also take a close look at the rubber insert for cracks, as well....

Considering the end result if it fails and the fact that they are at least 15 yrs old it isn't a risk I am willing to take. I guess you could get the situation where you bought it new from ford then had to pull it for some reason. As far as OEM to the car goes, when I remove them I recycle them.
