Poppy510 Posted December 26, 2020 Share Posted December 26, 2020 Thanks to this website I inspected the blades on my 1929 DB Standard 6 - and found a pretty major crack on one of the blades. The second blade was fine. I checked Myers...does anyone have a solution or know where a replacement might be available? So far all seems well running only one blade, but I wouldn't want to spend much time sitting still! Link to comment Share on other sites More sharing options...

This topic however serves as a warning to all, how many of us have used the fan blade(s) as a lever to turn the engine over ? Sooner or later stress cracks will develop, the added vibration and centrifugal forces aren't helpful either, maybe time we all had a close look.

Bullfrog_eng Posted December 26, 2020 Share Posted December 26, 2020 Had a similar problem with my DA some time back. From memory I used a Valiant (slant six) fan. Not sure if they are the same in USA, but suspect they would be. They only need minor modification to fit, again, from memory, centre hole bored out slightly, bolt holes elongated slightly. Could not find an original one to use that was not also cracked. Also discussed at Some clues there for you as well. Good luck. John Link to comment Share on other sites More sharing options...
edinmass Posted December 26, 2020 Share Posted December 26, 2020 The cracking in the fan is common to many cars of the era. Also look at your wheels.......hubs and rims. Lots of wheel failures today......the wheels are approaching 100 years old. Most people are too lazy to strip them all the way down........when you have a wheel pass you on the road at 45 mph, you will wish you did.

nearchoclatetown Posted December 26, 2020 Share Posted December 26, 2020 I would not run with only one blade. Find a replacement before you need a radiator core. Link to comment Share on other sites More sharing options...

Find a replacement before you need a radiator core. 1 blade will tear things to pieces. You can modify a plastic fan to work, or find a shop to do it for you. The Model A Ford stores sell them for those makes. You can go for a drive without the fan. It only is needed when you are going very slow and no air is going through the radiator. I have gone 50 miles or so without a fan when I lost a belt on tour. Edited December 26, 2020 by JFranklin (see edit history) Link to comment Share on other sites More sharing options...
JV Puleo Posted December 27, 2020 Share Posted December 27, 2020 If you can't find a close replacement I would run ANY fan that worked, even if it was a modern one with fiberglass blades. A cracked blade breaking free will almost certainly ruin your radiator if it doesn't do much worse...I've dealt with engines where the owner ignored this problem at least twice and in both case the repairs were much more expensive than a replacement fan. Ans, as J Franklin correctly points out, running with only 1 blade is a sure recipe for disaster. Link to comment Share on other sites More sharing options...
Poppy510 Posted December 27, 2020 Author Share Posted December 27, 2020 (edited) I hope to find an original replacement unless I can find a modern alternative that looks "mostly" right. Hopefully someone here can point me in the direction of a good modern replacement. To clarify: the fan assembly is made up of two pieces with two blades per piece. I am running one "piece," so there really are two blades. Everything is balanced and fine.

Poppy510 Posted December 31, 2020 Author Share Posted December 31, 2020 For anyone interested, the Allstar Pro fan does not fit. The steep pitch of the blades results in a large offset and the fan wont clear the radiator. Still searching..... Link to comment Share on other sites More sharing options...

The leading edge is not flush with the mounting surface like on a flex fan. Link to comment Share on other sites More sharing options...

It’s a 74 mustang 4 cylinder with 17,000 miles on it. He also had a 72 mach1 mustang that he bought at the same time. Kinda wish he kept that one instead of the pinto. But it’s a good original car with all the receipts and shipping documents. “It’s an old piece of shit” Dads words not mine 😂 If I can pull myself away from the roadster long enough tomorrow I’ll measure it all up.

Poppy510 Posted January 4, 2021 Author Share Posted January 4, 2021 Im confused. Is it a Pinto or a Mustang? I dont think Im going to be happy with the look of a new flex fan, so I'm eager to source one from a Pinto or Mustang. Link to comment Share on other sites More sharing options...

ArticiferTom Posted January 4, 2021 Share Posted January 4, 2021 I finial found that thread again, reading over it . I gave incorrect info . the Pinto fan was for a Pontiac . The Chrysler used a 1950's Chrysler fan . Ebay shows a couple different types of those . No other specifics where given . There where some measurement on the fans . Will have to try and get some from my Dodge to cross . Hope someone come thur with exact info ,too . Link to comment Share on other sites More sharing options...

Every fan blade from this era that I have checked has cracks in it. I was aware of this and had my fan blades reinforced, but they still broke. The cracks may be subtle and hard to see, but I promise you, they are there. I modified a fan blade from a 1950 Chrysler. It looks like a 98% perfect match and 3000 times safer. Don’t let it happen! It’s not a matter of “if” it will break; it is a matter of “when”. Getting cut in half with a fan blade is guaranteed to be a bad day. Not only Dodge but all pre war car fan blades. My Pontiac threw a blade 35 years ago but only bent radiator fins. A pinto fan fit perfect just needed to have two holes drilled to match the three bolt hub. This should be posted somewhere so all pre war drivers will know to check their fans. Copy of that post . Quote Report 1 Link to comment Share on other sites More sharing options...
Fossil Posted January 8, 2021 Share Posted January 8, 2021 Since this was posted I've gotten in the habit of checking the fan often. So far no cracks and thanks for the reminder. 1 Link to comment Share on other sites More sharing options...
Poppy510 Posted January 9, 2021 Author Share Posted January 9, 2021 So the Derale fan didnt even come close to fitting. It had a 1.5 inch offset from the mount to the blade leading edge, whereas the stock fan is .75 inches. https://www.amazon.com/gp/product/B000CN6U1I/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 Now I have a 74 Pinto/Mustang fan on order.🙄 Link to comment Share on other sites More sharing options...
MikeC5 Posted January 11, 2021 Share Posted January 11, 2021 I took a close look at the fan from my '25 and although I didn't remove the paint, a close look revealed nothing I could see with a magnifier. I'm still going to Zyglo inspect it. The construction of this fan is different in that a thicker material is used for the hub piece that includes the twist for blade angle and the fan blades are riveted on it. It seems like it would be more crack resistant. I have no way of being sure this is an original design to 25 but if it is, it might be an alternative that can be adapted to the later models. Let me know if anyone would like some dimensions. Link to comment Share on other sites More sharing options...
Pete K. Posted January 16, 2021 Share Posted January 16, 2021 Same exact fan on my '25 Tourer Mike. I can't find any signs of cracks on mine either but I sure am listening to the guys on this thread. Link to comment Share on other sites More sharing options...
