How does a generator fan work?

The fan in a generator or alternator system is attached to the front (front is the part facing out of the engine) and is driven by a belt from the crankshaft pulley. It is encased in a fan housing (often referred to as the fan shroud) which is attached to the engine tin to make an air-tight assembly. This design ensures efficient cooling of the generator or alternator.

Where is the fan located on a 59 stud generator?

Depends on which 24 stud (year). If you are talking the '38 (& my '39 std), the fan was mounted to the front of the generator. "59" blocks had a fan that hung from the front of the intake.

How do you mount a fan on a multi carb manifold?

With a multi carb manifold or just an alternator with non-Ford mount plate there are several strategies to mount the fan where Ford put it, using Ford bits, aftermarket bracket, or very simple constructions of plates witha few holes drilled. Sounds like this is not an uncommon issue.

Do you need a band saw to build a fan?

Building fans is not a complex process, nor are specialized tools needed. The most important item to have is a 3/4-inch-wide blade (with three to four teeth per inch) for your band saw. When re-sawing, a wide blade keeps the cut going straight as it runs into the wood’s grain (photo 1).

How do you remove a fan from an alternator?

To remove the fan from the alternator, you need to loosen the big nut on the forward end of the alternator shaft. Some suggest using an impact wrench, while others recommend putting the pulley in a vise (padded with an old drive belt) and then removing the nut with a 1-13/16" socket.

How do you make a fan blank?

When you find an original fan section, the paint is often thick where it puddled after being dipped. Blanks are made by cutting a 2-by-6 on a diagonal (photo 2): Make the narrow end 1-1/2 inches wide and that ensures a width of about 4 inches on the wide end. If you cut the first pair carefully, you’ll have blanks to use as guides for the rest.
