Fan Drive Pictures

[Steve/IL]

I have searched Ford Barn and the internet for Fan Drive pictures of the following:

48/49 Truck
49/50 Mercury

I am not sure what are the fan drive differences between these two vehicles, except that both have a wide belt pulley and are the non-oil filled type.

Hard to see and compare on an engine and in a vehicle.

If possible, any pictures of these fan drives off the engine or in the vehicle without the belts getting in the way of the picture?

Thanks,
Steve

I was never around a Mercury but the trucks I was, were oil filled.

The drawing in post #2 is an oil-filled fan. These BELOW have what are like water pump bearings. Coop

STEVE:
Here's some photos of the 8RT wide belt truck fan hub pulley that contains oil. It has a 5/8 inch dia. shaft which means it requires the bracket that has the 5/8 hole and the 2 bolts that secure the fan hub pulley shaft in place.

Some other fans have 3/4 dia. shafts so make sure you use the correct fan bracket for the shaft size you are using. The green bracket shown below is an aftermarket that has the 2 holes required for securing the 5/8 in 8RT fan hub shaft.

The engine shown in the photo is a later 1951 Mercury and Ford style 8BA that utilizes the 2 narrow belt pulley system, not the wide belt system of earlier years. I was just check the mock up of the green pulley bracket for a project I was making. Get the correct matching bracket that comes with your fan hub shaft.

Steve, If you don't mind me asking, why do you need this info. Is it for a project you are building? May I suggest that you consider using the after market wide belt pulley that uses quality ball bearings and no oil. Here it is:

Gentlemen, thanks for all the pictures and information.

V8COOPMAN,
From your post #4. The fan hub and pulley in the last two pictures is what I'm looking for! They appear to be wide belt pulleys? What year and vehicle are they from?

Not my project looking for a friend. I like the Bob Drake hub and pulley except the it is for an eight bolt fan and my friend is cheap. I used a 41-48 oil filled fan in my last 32.
I have a fixture to drill the fan mount to four bolts in order to use a narrow depth aftermarket fan to clear the water pump pulleys.

You may be correct, but what do I know? That MAY be for a '49-ish Merc ("8CM")! Coop
