Does anyone know the size bolts? I have located a matching 5 blade and have the metal ring, but no bolts to mount it on the hub.

38 Coupe, I see you changed the pic you posted, where was that one from, as it indicated the fan part # to be 8602?
Anyhow, Part #B7Q8600c
Dennis Carpenter has 2 NOS
Klimesh Motor Sales Calmar, IA 52132 has 2
Miller Obsolete Binghamton, NY has 1 $90.00
No problem, thank you so much for the specs. I could not find them anywhere. Do I have a major problem with the pulley? It slides freely from behind the mounting ring aft to the motor on the shaft. Something just doesn't seem right with this?
1/16" long? I measure 1/4" diameter and 28 fine thread. I have another problem. The pulley for the fan is freely sliding from mounting hub. Is it supposed to do that? If not, how do I fix it?
Here is the list of screws and bolts for the assembly
EDIT: Just relooking at the chart, the 48-51 Big Job 337 fan hub had 1/4 x 28 thread x 3/4". Maybe somebody changed out the hub before, if so the parts list is just above the second group highlighted. I edited the picture.
I think your right, because it is a 239 and it had an electric fan on it. The pulley behind the hub is not firmly attached to the shaft. It does stop turning when I hold it up close to the back of the hub. It does look like there is a gasket between it and the hub.
The fans on these are opposite from most modern setups. The shaft is held firm, and the pulley/hub/fan spin on that.
I understand the spinning freely, but it slides back and forth along the shaft. The last thing I want to do is to put a belt on and throw the fan. It looks like there is a sleeve or something missing to hold it firmly on the shaft.
