Does anyone know the original measurements of a crankshaft is. I tore into my lo-boy the other day and found the crank in 2 pieces. I have never seen an engine run with a broken crank before, but I have to fix it. Also can someone give me an estimate how much it would cost to turn a crank? And while I am at it where is the best place to purchase new bearings. thanks guys.......

yup, if the break in the crank is at an angle an somewhat supported, the break will turn cause it's pressed together and the engine will still run. i had an Artic Cat snowmobile that i ran 250 miles with a broken crank. I noticed it started shaking a little and loosening up bolts. got worse and worse and started burning up the drive belt. limped it back to the hotel on the road. i was stunned when i took it apart, because those motors turn 9000 rpm :!: it should have grenaded.
