Has your crank pulley ever fallen off?
So as you can probably tell from the title of the thread I'm dumb. And apparently I forgot to tighten down the crank pulley bolt enough a couple years ago when I hastily built a motor and swapped a blown one out in one weekend. The car was idling on the turbo timer when I heard a weird noise, thought it was the neighbors RC car and then the car shut off ten seconds later like it should. Fired it back up a couple minutes later to go around the block and didn't have power steering. Drove for maybe 30 seconds before I got out to look what was wrong and found the crank pulley sitting there crooked and not turning. Car shut off. I put it back on real tight without the key, drove around the block again to make sure it wasn't gonna explode and parked it back in my garage. I guess my question is has anyone else ever been this dumb and gotten away with it? I wanna just stick a new key and pulley back on it and call it a day but I'm scared that the snout is trash. Advice, comments, tips? I'd really hate to have to rebuild a motor over something this stupid. Not to mention its literally THE WORST PART OF THE MOTOR THAT COULD BE FUCKED, and in the shittiest way possible...

Pulled the oil cooler off and in the process of pulling the lower pan to clean everything since I'm pretty sure the key disintegrated and made it's way into the oil. Had to stop for the night because I don't think my neighbors would appreciate me bashing the lower pan off with a hammer at 11 PM.

I once shoved my pulley on, smashed the key into the pump damaging it...replaced pump, key and the then cracked pulley and it was good...look at all your stuff to make sure is within specs still

Well I dropped the lower pan and oil cooler and cleaned both out best I could with acetone in case shavings of the crank snout and key made their way into the oil. Cars all back together now, just waiting to find another crank pulley.

I've always, (only had to do it 3x since 2006) used an impact. I've never had a problem. I could not find a reasonable way of locking the motor in order to tighten per torque wrench. To be honest, I never researched how to do it a feasible way.

I normally put the motor together then tighten the pulley down when the motor is in the car with the ebrake up and trans in gear. Thinking back to when I built this motor though I don't remember doing that... Must have forgotten about it in my haste

I would never crank to tighten, a starter is strong enough to bend a rod. |
