If the harmonic balancer goes out will the belt get tossed? Just wondering if anyone had this problem before?

my dads 80 bronco with a 302 cracked the balancer bad infact a piece of it broke off from we ended up buying another motor fir it cause it ruined the crank. from what i understand from the machine shop we took the second motor to (we rebuilt a yard motor) this problem happens more than most think it would but i dont remember what exactly the cause it i think it had something to do with the keyway on the crank

I have seen it on a 79 Mustang due to over reving the motor. (Not implying that you did this). I was like 19 years old and very inexperienced and learned that stock motors will not do 7k plus rpm for long. Note to self never floor a Mustang on a gravel road without a rev limiter. lol Good thing I did it though since that's what got me into rebuilding engines.

You say you replaced it 3 months ago - if there was nothing wrong with the key-way/crank/threads when you took the old one off, I'd say the odds were high that you did the damage when you installed the replacement balancer. Sounds like you pulled the new one on with the keyway misaligned. In any event - looks like you get to rebuild the engine as the crank will have to be replaced.

How did you install the balancer? If you feel that the part was installed correctly, then I would definitely take it up with Kragen. There is a lot of junk being sold by the auto stores, alot of cheap chinese made parts, and the quality is for crap, and are causing alot of engine failures in other brand motors too. Dont buy the cheapest part you can find, do some research, and buy quality. It will save you alot of money in the long run.

Chance for me to learn something here - I'm wondering how a defective balancer could cause threads inside the crankshaft to become messed up?

Did you read the instructions or manufacturers specifications? MOST stock replacement aftermarket balancers (not romac pioneer etc) only recomend that the motor be revved no higher than 4500rpm or so.... If the car was driven like most of us do, you pretty much void any type of warranty that could have existed.

i found out the hard way on that one,i bought a new summit brand balancer for a small block 68 nova i used to have and it said not to exceed 4500,well after a few months of d/s running it let go and thank god for the crank pulley catching it,but it didn't tear up my crank.
