Im removing my crank because Im doing some bottom end work on my B18C. Now Ive heard that if you lar a crank flat down thast it throws it off balance. How should I place the crank so that it isnt off balance?

 

Ive laid many cranks flat on the ground or on its end for months at a time, then used em without problem.

How can people actually believe that laying on its side it will deform under its own weight yet it shrugs off 500hp? Give me a break.

 

After a while they will warp, so if you can stand it straight up or hang it up somewhere it will prevent this. All the machine shops I've been to hang them on a bracket. It takes a long time for it to happen, but it does happen. Just like looking at 50 year old glass, its thicker at the base than the top.

 

So standing it on end wont warp it but laying it on its side will? When its on its side it will contact the floor in more areas distributing the weight more evenly.

 

This is a game of leverage, standing it up imparts a potential energy due to the height of the crank, but placing it on its side allows a mechanical advantage of the crank, so it will use its own weight and length plus the force of gravity to bend it, which is significantly more than standing it up, which implies no energy outright (hence the word potential). If you could support it sideways perfectly, like it is in a block, there would be no problem, because no mechanical advantage exists in that setup.

 

Did you just pull that out of your *** bc that stinks like BS? lol

Take a pole and stand it straight up in the air, and note how it stays upright, and then take that same pole, and stick it straight out in front of you, and watch it bend. Energy increases as distance from the supported point increases regardless of the objects actual weight. This is the same concept behind a breaker bar.

So in a nutshell, if a crank is not supported equally and completely flat on the ground, there will be a force acting on it that is equal to the distance of the lever. (the portion of the crank that is supported, to the endmost point that is not) This is your mechanical force. Standing an object up will create an energy that is potential due to height. Having a ball in the air at 1000 feet implies no energy until it falls, therefor the only stress induced is that of the ***** weight and the force of gravity, with NO MECHANICAL ADVANTAGE.

Ask yourself why skyscrapers stand straight upward, and then look at bridges and how they are supported. That is mechanical advantage at work, greatest at its furthest applied point, regardless if it is supported on two sides or not. A bridge unsupported would sag in the center, which also happens to be the farthest distance from either applied point. (the bridge ends)

Oh, and another thing, why don't you post something productive that proves me wrong, looks like you need some new deodorant...

 

hahahaha that was great. Wow i learn something new everyday. You know any basic time frames that it would take to have a slight warping? This is news to me.

 

I dont really care to debate any of that. I just think its extremely insiginficiant.

 

it would prolly take 50 years for the crank to bend ever so slightly..
