Is it true that if you lay a crank shaft on its side it will warp??? I can't wait to hear the opinion on this one Thanks, Terry

Re: Here is one for the books......
just had an out of the box nos 6223 crank straightened at castillo (sp) crank service---as with any cranks shop all of the cranks were standing up for storage reasons---he said the heat treating caused the cranks to warp---mine was bent .0035---i was amazed at how little force with a chisel and medium ballpeen hammer it took to straighten the crank---i asked if a crank fell over would it bend it---he said possible but not likely---i asked if it could have been bent during shipping and again he said possible but not likely---Comment

Yes, but only on a floor where Ford oil has spilled!

Re: Here is one for the books......
The crank won't bend if it's near a Ford...it will melt due to the searing heat from the Ford self combusting. Want Proof? If I can figure out how to put pics on this site, I'll post pics that will prove it!Comment

Ha! Once I
needed a 350 crankshaft to finish an engine. Found one half buried in the soil behind the shop, had been there for years. It mic'ed within limits, so after a very thorough cleaning, I put it in the mains and Plastigauged it, still in limits. Assembled the engine, which became the #2 (RH) in my Dad's offshore deep V powerboat, engine held up just fine while extended cruising at 6000 rpm..Comment

Jeremy, we do not need flaming 6.4 pictures on here. This is a Corvette site.Dick WhittingtonComment

Re: Here is one for the books......
i have installed cranks the showed .003 run out in the center main bearing in a block with .0025 bearing clearance and you could still turn the crank with 2 fingers.Comment

Re: Here is one for the books......
I'm just happy that my LT-1 was in my detached garage while my house was burning down to the ground. That's what happens when Ford cruise control switches fail in the middle of the night while you're sleeping. What's a 6.4, anyway?Comment

Re: Here is one for the books......
Ford had problems early on with the new diesel, seems that they would shoot a flame out the exhaust. Sorry for the loss of you house. Main think is that you are okDick WhittingtonComment

Re: Here is one for the books......
Best part was...I had a 55 gal. drum of Cam2 110 Octane racing gas that I had just bought in the barn, right under my car (car was on a lift). I told the fire department at the time to make sure that the barn was saved, otherwise it would blow a crater in the ground when it went up. They asked me if I had any bombs/firearms in the barn, and I said "No, but there's 55 gal's of rocket fuel in there that's 110 octane!" They went nuts...soaked the whole barn down with water, and luckily the fire never got bad on that side of our house. The barn was untouched.
Sorry I came unglued....I have a SERIOUS resentment towards Ford, and I used to be a definite Ford Truck guy. Now, it's Bowtie all the way. Those bastards can't even admit it was their fault, even though their own investigators told us off the record that it most likely was. Oh well, I hope I get to dust a few SVO's this summer for my own little revenge....Comment

Re: Here is one for the books......
I should get a special award for starting the weirdest posts. Anyway, I was reading some on some site that described proper methods of engine rebuilding. Guy stated you should never lay a cranshaft down because it would cause it to warp in a short period of time. I thought that was nuts!!! But, I had to try it out on you guys. You never know what you might learn. I would think that under a normal heat cycle, the crank wouldn't exactly expand and contract perfectly. I bet it sort of wiggles around a bit. If you want the web site, I will have to try and find it again. I printed it out though. I purchased those springs and reatainers. I will have to buy just the one spring. I ran across a std/std 6223 crank and bought it the other day. I have two now. I will take them to the engine balancer and let him pick the one he wants to use. I have know idea what he will decide or say. A crank isn't a crank untill it is confirmed straight. I got a good deal on the one crank. Thanks, TerryComment

Re: Here is one for the books......
I was told many smelt seasons ago by several machinists to always stand cranks on end, So that is what I have always done. I can see why some may not like that way because a child or animal may knock it over.Comment

Low tech way to tell
If the crank is in a running engine when disassembled and the block checks out as straight and the crank spins freely, I never bothered to check it for straightness - 20 years later, still no crank or bearing problems. From what I heard, MANY BB cranks were NOT straight from the factory, but ran fine anyway.
