Re: Cracked Fan
I agree with Ned in post #19. I've had three close calls with old fans. As a side note, the old model 46 four blade 1933 truck fans that was sold as a replacement is just , if not more dangerous than the old original Fan. I use the new repro aluminum two blade fans because they look original and have worked flawlessly for me since they came out in the 70s .

Re: Cracked Fan
Has ANYONE heard of one of the new type aluminum fans breaking? Surely, they must be made of a "special" aluminum alloy?? NOT beer cans!

Re: Cracked Fan
My coupe was coming back from a show that it won Best work in Progress Lol told them I thought I was DONE with it but none the less LoL was a win! Coming home I head a weird noise. The ole lady named it Shake Rattle and Roll lol so there is lots of sound on my old car not to mention the metal roof they just screwed down on top. Anyways lol the old lady goes what noise? Lol I pulled over to see my 4 blade fan scraping on the radiator a very nice half moon circle. Took the belt off drove it the rest of the way home. I was VERY LUCKY my radiator is still Good Thank Goodness. Went out and got a beer can 2 blade and works Great for the past few years but I always check it every week just to make sure.

Re: Cracked Fan
Thanks guys. Very appreciated. Decided to get the 2 blade aluminum fan, balanced and powder coated. $54. Good opportunity to replace my radiator hoses, clamps and put in a thermostat. Anything else I should consider doing, during this repair?

Re: Cracked Fan
Well, if you ever thought about putting in a temperature gauge, I suppose this would be the perfect opportunity/excuse to do that as well.

Re: Cracked Fan
No overheating issues with the new radiator.
I will do bolts on the water-pump. I installed my new repro cast aluminum fan yesterday and found that the water-pump has a crack on one side of the housing. Wonder how long that has been there. Just noticed it today as I started it up to see the crack while it was running during my inspection of the fan replacement! Darn. Time to pull it all back apart. Good time to upgrade water-pump for use with my new thermostat. Any advise for a new water-pump?

Re: Cracked Fan
By all means replace it. We just had a young mechanic locally die from a fan blade that flew off and severed the artery in his neck. A very tragic death.

Re: Cracked Fan
Well, there are those who "trim" an original fan back an inch or two on each side. Centrifugal force is the square of the diameter and this lessens the loading on the center considerably.
You could trim this one back to the crack - balance it off by trimming the other side to make it balanced - and then drive ALWAYS above 20 mph in the car (since the fan does no function when driving that fast or faster anyway.) All except the first paragraph offered in good fun - and that first paragraph offered as concern. Joe K

Re: Cracked Fan
Nick, you -be-lucky
From the looks of that garage wall art piece, I'd go buy a Lottery ticket after you place your order for a new aluminum fan. And as someone said DON'T run that engine until you replace that bad boy she's ready to come apart. Good thing you checked it. |

Re: Cracked Fan
Nick,
I put the leakless pump in mine that I got from Snyders. Part # A8503-B. No leaks, no greasing, looks correct and no cleaning the firewall after I drive it. I think it's the best way to go. I rebuilt the old one as a spare. Joe |

Re: Cracked Fan
Considering the mega posts about the perils of running an original fan, I am amazed that some are still in use! Nickair, you are very lucky that your fan did not throw the cracked blade.
There is absolutely no way to determine the remaining life of an original fan, and we do know their life is very finite.

Re: Cracked Fan
You ere very lucky you discover it when you did. The next thing would have been damage to the hood. I would replace it with an aluminum fan and you could replace the studs for the water pump with the new bolts that look like studs, so in the future you can remove the water pump without moving the radiator. I have seen some nasty damage to hoods and radiators with the original fan blades.

Re: Cracked Fan
Just ordered the water pump bolts. Now waiting for the extreme duty waterpump. Im thinking that I may as well get a new high compression head since I could do it now. Suggestions?
