Model T Ford Forum: Forum 2017: Fan rivets, screws, what?

I keep seeing comments on replacing fan blades about rivets. I got my new production fan and the one piece roller bearing hub in from Langs. The fan is held in by screws with lock washers, am I missing something here?

Matthew, the earlier fans had 4 separate blades which were riveted to either a brass or iron hub. Your sounds like the later one piece fan fitted with 4 screws to an alloy hub.

Allan from down under.

Ah, yes, that makes sense. Even the original one is set up with screws. I've noticed I have the later 27 style fan hub that pushes the blade real close to the radiator, the new style one won't push the fan that close.

If a blade flys off it can cause a bunch of damage. I would use Locktite on the screws

If you have the Ford hub that has the blades close to the core. You may have one of the 3 row core radiators. The fan was moved to help cool the undersized radiator. Dan

Don't forget Ford made a fan pulley with a longer nose that put the fan blades closer to the radiator.

There are two styles of bolt on fan blades. I'm not positive when the new style came out, but it was probably 1924. The new revised guidelines doesn't mention when the change occurred. I'll contact Russ Furstnow, and see if he knows anything.

Ok you do all the work to rebuild the fan with either screws or rivets, or you purchase a rebuilt/new fan to replace the the existing fan, is there any consideration given to making certain the fan has been balanced to eliminate unwanted vibrations?
