64.5 Generator Question - need help

Rocket · February 18, 2010 at 10:29 PM

What are the identifying numbers and location(s) of casting numbers, date codes etc. for a correct generator?

The HP Mustang Fourth Edition details the casting #s for a generator pully, but fails to provide identifers for the generator.

I have found several markings on my generator and would like to confirm that it is correct. I have failed to identify any discernable date code.

This is what I have found on the case - Ford stamp, FBC-10125-A, I also found the following stamped numbers on the back side of the brackets - FAB10139, an upside down 4, an 8, GFA and a B on one side and a 24 on the other side.

Any help would be greatly appreciated.

Generator were stamped. The 64½ Mustang would have carried the number C3OF-10000-B. Generator numbers were always specific to the installed the pulley.

Thanks Bob

My car has a Generator Pulley # C3OF-10130-B, which is correct according to the HP Mustang 4th Edition. So would it be correct to state that the Generator must also have C3OF-10130-B on it to be correct?

As referenced above my Generator has varous numbers on it and the flange/hangers but none are identical to the pulley number.

Can you tell me exactly where these numbers should be located on the generator?

Thanks

The generator number was specific to the installed pulley. A C3OF-10000-B generator number would have come with the C3OF-10130-B pulley. There were two styles of pulleys used in 1963 and 1964. One was stamped C3OF-10130-B and the other C3OF-B.

Stamp placement varies, but the attached PDF file will help you place it in the right area. Also, the included graphic is an accuracy redition of the stamping.
