Ha, probably not. At some point I want the shiny new powdercoated one in there. I'll pull my in-decent shape fan out and probably sell that one at some point in the future, but at the rate I get things done on my car, it'll probably be next year!

this is gonna sound real stupid. So I talked a gear head friend at work about this problem.
He told me to cut the fins that have cracks off in the mean time. until whenever new unit is ordered. I probably would never do this. but is he making any sense?

Absolutely NOT a good idea. What would happen if you removed a blade from your ceiling fan?

lol. i will give it a try on a ceiling fan.
on a serious note, Another member here told me one possible cause is due to mechanic jammed the fan with an object to help removing the center nut.

Interesting crack.
The outer portion looks like it was the result of someone jamming something in between the blades to hold the fan in place to loosen or tighten it.
What intrigues me is what looks like a crack along the parting line I boxed in blue.
Can you tell if that is a crack or dirt in the casting. From what I see is a crack along the parting line which is normally not the case and may be a manufacturing defect as well.
Would you mind posting more pics of that area when you have it removed I would be curios to know the extent of the crack.
As said one huge mistake and I made it myself 25 years ago is never use anything to wedge between the blades to tighten or loosen the belts. You might not see any damage initially but the elements and outward force of the part spinning will make it worse over time until it fails and never cut or do anything to alter the balance of the fan. Even painting should be done evenly so it doesn't throw off the balance which will eventually damage the bearing.

I just looked at that area in more detail too... Was wondering if that was exaggerated because of the flash causing a shadow?
Thanks for highlighting it C.
