On a cherry picker and down the 440 went. Landed on the crankshaft pully and broke the end of the crankshaft clean off. I am by far not a motor guru and I know that I need a new balanced crank and to balance I need to get a machine shop a piston and rod. Should I attempt this myself or just drop off my motor? I have a highly recommended motor guru who I can have do the job.

UMMM,, WOW, I would definatly have that block checked for any cracks from the impact. Every main got a shock when that ol girl hit, and I mean a side shock, stressing the bolts, and the webbing of the block where a load like that was NEVER designed to hit it. Crazy how that broke. Glad you arent hurt, that could have gotten really nasty. Kasey

I got a cherry cast crank that you can have if you want to pay shipping from the east coast. Should be able to find one out there for less than shipping though.

If you look at the squareness of the counterweights you can tell it's cast, plus, a forged would likely not have broken like that. Regardless, I doubt it hurt the block, but I would replace at least that one upper main bearing on #1. If the motor is stock (factory rods and pistons) another stock cast crank that has never been molested should be close enough in balance. If it bothers you, definitely have the balance checked. Take the harmonic balancer and let them know the rear is also externally balanced. If you have a stick trans, take the flywheel, otherwise you're almost stuck buying a B&M external flexplate.

Thanks for all the great information guys. I really appreciate it. I am going to tear everything down myself and inspect and retorque everything. I will use Johns crank as a replacement. I might as well do the cam too while I am at it.

I have to ask, what engine hoist were you using and what was the failure on the hoist?
