40 ford belt
Are there 2 different length belts for a 40 Ford? I am not sure but did the have a 3 11/16" pulley or a 3 3/16 pulley on the generator which would change belt length. I have a 3 3/16 pulley on gen. and seems like the belt may be a little on the long side. It is #241 made by a company called US which in old NOS. Working on a 239 engine.

There were in fact two different fan belts respective of the two different pulleys that were utilized in 1940. The first pulley was 3 11/16" diameter and required belt 78-8620-A, inside diameter 50.83". The second design pulley was 3 3/16" diameter and was placed in to production approximately June, 1940. I have noticed that most cars being pit judged on the concourse have an incorrect pulley. The later, 3 3/16" pulley required a shorter belt than it's predecessor. That belt was 78-8620-C, inside diameter 50.06".
