cooling fan and sticker mark on trunk deck

[69Z28-RS]

i need one of those fan blades if someone has one for a reasonable price. mine blew apart at the pure stock drags. '68 L78. i attached a pic but don't know if it will show up.

Wow!  I've never seen a factory steel fan blade come apart before!

in this pic you can see where it was cracked to the right of the right hand bolt. it just let go. luckily it went down and to the right in the area of the lower rad hose.

A good welder can fix that. Not sure I'd run it at the drags though....

right, ok for show car but i would not want to have it hurt someone down the road. i was very lucky it didn't hurt me or anyone else. could have been really bad had it happened on the track. we were doing some spirited driving in the pits checking something out and it let loose. check your fans, guys.

 Here is a few more pics of the fan i tried to use a tape measure to show sizes as best i could, looking to see if its real or repop?

Looks like 3-1/4 BC to me, markings correct. I'd venture it's the genuine article -

Paul,

I take it by the two washers under the bolt heads that the bolts likely bottomed out before proper torque could occur - wonder if that affected the fatigue that ultimately broke the fan. Bent or loose on the clutch probably accelerated the breakage for sure, especially if it was cracked on one side.

Kurt"s right - I'd have a competent welder repair it and put it away (or street it) - they're just too hard to come by. Run a lo-po at the drags if you want the appearance; the diameter and pitch are the same, and they sure are easier and cheaper to locate (also reproduced).

no the bolts did not bottom out. i just customarily use a flat and a lock on this type of attachment. clutch was purchased new by me and has seen lots of duty. all ran very straight and smooth. i believe this fan is original to the car. i'm not going to weld it. it's wall art now. i'll find a used one someday.
