Hi Mariano,

I think that may be a civilian fan setup. All Ford CMP's engines I have seen that are correct have twin row pulleys on the crankshaft, water pumps, and the generator as per photo of mine. The fan is definitely attached to the twin row pulley on the generator. A fan shroud, if fitted, goes around the fan to improve the air flow through the radiator. At the location shown in yours it would be too low on the radiator and would not clear the shroud.

Added Info: I checked the 1940 parts catalogue as a second source. The same shroud is specified for all models of the early CMP trucks depending on engine s/n's so if that holds true for cab 13 models it confirms the above.

Added unobstructed view photo of crankshaft double row pulley for your info.

Hope this helps.

Cheers,
