Wrap in in newspaper and stick it under your bed. You can do anything, just make sure you don't scratch the journals

You should store a crank standing up. Most if not all machine shops that I have visited store thier cranks standing up or on a crank stand. They do that to make sure the cranks do not bend under the loads of the heavy counter weights.

I am not flaming you. I don't understand how a crank will deform under its own weight, considering the forces exerted on a crank spinning at 8k rpm. Can you shed some more light on this for future reference?

Usually the crank is supported by the 5 caps when the block. The crank is designed to be very strong in torsion, not in bending. So if left in a position to allow it to bend, such as on its side and under its own weight, it could be a cause for bending, but in most cases that would probably take a good amount of time...

I understand that line of reasoning. But, how would the crank deform less stored on its end than stored on its side?

And like you said, is this really a concern? How long would a crank have to sit for it to bend?

Because the counter weights balance the block while its rotating htey off set each other when standing on end. It shouldn't be a huge problem, i've never had a problem with it, probably the biggest way for it to bend quickly would be the temperature you are storing it. But it would have to be in a pretty hot environment for it to bend that quickly.

i cant see a crank warping under its own weight ..that sounds very far fetched.....

not being a dick but logicly it should be fine ....and i would thing that if this were treu it would bend more stnding up than laying down
just my opinion though

now im taking a couple of bottles of wine out and get twisted
and place my crank in the wine cellar LOL

common its a forged crank standing or laying it will see no deffects
unless some type of major impact causing it to bend or affect the
journals so just wrap it up put in a box and keep away from any sharp, heavy or pointy objects

if it is standing on its end it has more stress on it in my own opinion ...


- stripped honda - one who cant believe a crank will warp under its own weight

Well whether anyone believes it or not, its common practice by machinists and shops. If you are storing it, stand it on end. The habit was made by heavier V8 cranks and warping is possible. Have all of you held a Honda crank? It's not as heavy as a v8 by any means but its not light either. Better safe than sorry, cranks are well balanced from the factory and delicate- don't mess it up.

LOL...

Man, when will this myth die...

If a crankshaft were to warp under it's own weight - laying it down for 2 seconds would have already done the damage. There is a difference between permanent and elastic change. You will not warp a crank by supporting it on it's counterweights.

Besides, I think this should settle it once and for all:

"The crankshaft itself has a length of more than 8.5 m and weight exceeding 31
ton. The engine (power more than 23 MW) 32,000 hp was put into operation in the
beginning of 1998 (power station in Vaasa, Finland)."
