i have a 1992 honda accord lx. Ok so i was driving on the interstate and all of a sudden my car starts making a ton of noise, I get home and realize that my belts are loose and the pulleys are not spinning. I dropped the belts and found that the harmonic balancer was no longer locked on to the crankshaft and the bolt that holds it on was loose. Apon taking the pulley off i discovered that the crankshaft is sheared where the wood druff key is supposed to be and the key is sheared away as well. Basically the crankshaft is still round except for where the key sits in and that part is near flat all the away across the top of the crankshaft where the the pulley sits on. Do i have to replace the crankshaft and is it worth it? I cant afford a new car or a new engine.

Unfortunately, replacing a crankshaft is only affordable if you do it yourself. It would be safe to assume around 15-20 hours of labor time. So it would be a safe bet to pay a good shop between $2000-$3000. Parts cost would be around a G.
I once replaced a crankshaft in a Kia Sorento that had the same kind of failure yours. You have to remove either the engine or transmission because of the way the crankshaft attaches to the flywheel/drive plate. It’s not the hardest engine work to be doing, at least. If your car has selective bearings (which it does, now that I’ve looked), that might take more thought than any other part of the job because all the main and rod bearings need to be replaced with the crankshaft. Just to be clear, I’ve never even heard of putting in a used crankshaft. It certainly could be done, but It’s risky.
Crankshaft is FUBAR now. Cheapest bet is to call a boneyard for a good used motor or junk the car. There is no cheapie fix here.
If you change the crank you need the mains align honed to the new set, which needs a machine shop. You’d basically be better off rebuilding the whole thing if you go that far, and a used crank isn’t worth it as you’d just have to get it machined anyhow.
Its a 23 year old car, how far do you go with it? A good used motor is worth it if the rest of the car is real clean and you are doing the work yourself, but otherwise this is going to cost you more than it would take to get a better car.

See the last four posts in the above thread. We were discussing this on another part of the forum.
