CSX2201 and later charging system components

[Ivygreen65]

Dan,


Would this type of Autolite stamp be correct for a later build date? I'm assuming Autolite changed the format of its stamp with the wholesale change from generators to alternators in mid-1964. This stamp is consistent with every original alternator I've seen on a post-August 64 small block Ford.

I have one if you are.

Well I was gonna but I would use yours!

I also have just confirmed production of the plug and harness assemblies. These will be as original style plugs with the terminals and molded back seal. The wires will be 14" to allow them to be mated into existing harnesses and will carry the original color codes.

I will announce pricing as soon as we have all the costs added up.

Yes, you can use it but it wouldn't be correct for the Cobra. I thought it was but I misunderstood a photo Dan sent me a couple years ago. The correct part number should be C3MF-10300-A.
If you're restoring a Thunderbird though, my stamp is perfect!;-)

The change in the parts division identification was a branding change and not a parts design change. Cobras were loaded with FoMoCo® branded parts. Some used AUTO-LITE® brand 12V batteries followed by AUTOLITE® 12 batteries. They used three rib AUTOLITE BF32 spark plugs. Ford purchased Auto-Lite in 1962 and slowly over several years changed the art and text of production packaging. At first they just added notations to earlier packages that the products were made by Ford.

The original post and my replies related to 1964-65 CSX2201 and later Cobra alternators used to build the cars new. As I indicated in the original posting commentary, I would not believe anything not a FoMoCo® C3MF-10300-A marked unit to have been something Shelby American built a new Cobra with if that is your question.

Should look like this:

Thanks, Larry. I have seen that style of ink stamp, with the FoMoCo inside both the block and oval. However, I had only seen the later style AUTOLITE ink stamp once on that particularly cased alternator, and it was for the C3SF part number.

[LMH]

Yeah, I've seen that one too. More common as it's a Thunderbird number but the Cobras used a C3MF unit. Hard part to find is the pulley!

Dan,

You have not addressed the housing casting differences, diecast or rough finished?

The aluminum case shells or housings were produced in permanent die casting molds. Appearance wise, Cobra production alternator assemblies had exterior case shell surfaces right out of molds. Any other case shell exterior surface condition, steel shot or some other hard media blasted, tumbled with abrasive media, strong chemical etching, or combinations of any exterior condition (for example let’s say front case as cast and rear case shot blasted) are indicative of typical service parts. Many of the brand new 1963 model year alternator assemblies I have held in my hands came out of boxes from one of the Ford authorized remanufacturers. The implication is that the Ford authorized remanufacturers had stocks of individual parts and they assembled whatever they needed to fill an order from Ford. Different rebuilders often used different case rework procedures and new small parts that may or may not have been like originals to make up complete assemblies. Once the as die cast exterior is changed it can't be reworked to look day one again, not 100%.

It was in the big commentary. I started paying attention when I serious started trying to find an unrestored significantly unmodified car to buy. That was circa 1977. Most Cobras were unrestored at the time and going to a SAAC convention 1978 -1988 could provide you with more unrestored cars to look at than you could remember. I kept a flip note book and took 35 mm pictures and made notes specific cars for years for all kinds of original parts in the engine bays. On really nice significantly unmolested cars there was either a completely smooth set of cases or some other type alternator altogether. At a SAAC regional event circa late 1970s I came across a CSX25xx street car that had been raced with a genuine 1966 GT40 alternator on it!

Production wise I have logged two different front cases, early castings without screw boss gussets and later (most) castings with.

I would assume FoMoCo as there is no reference to Autolite in the specifications.

[Mark IV]

Well they have arrived! The first batch are being packed and shipped to the orders received so far.

These came out very nice and have 16" of wire to allow ease of integration to an existing harness. They have the molded rubber seal as original and the correct wire I.D. stripes.

Working on a new supply of the alternators and possibly a repro of the correct pulley/fan unit!

[LMH]

Petty cool!
I bought the last original DST alternator fan/pulley from old unsold stock. There aren't any more originals, so a repo might be a good idea.

[AndrewB]

They look great!

You would pretty much be my hero. I was resigned to the fact I was going to have to run the smaller pulley version, so I would certainly be in if you were able to repro the fan/pulley setup. I'm getting ready to refurb these guys here soon.


BTW: Notice how the one on the right has a rounded case? Any ideas where that came from?

[LMH]

The one on the right is pretty close to what the Cobra used, minus the pulley/fan of course.

Larry, I'm confused. What is the correct pulley/fan. The one I have looks just like the one on the right with a code of C3SF-10344-B. I also have a double pulley fan C3SF-10344-A

Thanks.

The original removed from CSX2332 circa 1972.

Nice. How about all the short wire looms Ford supplied? I know it would help some original car owners out if new pieces were available.

Be aware that the common 427 Mercury and Ford sheave and fan assembly and the common original Cobra sheave and fan assemblies are somewhat different. The differences are believed to be only because different subcontractors made the parts and did the final assemblies. I have seen reproductions with mixtures of Ford and Cobra details.

Thanks Dan, I see the difference in the pulley size. Oh well, mines a replica so only the most discerning eye would notice the difference.

Thanks Dan!
As you see on Dans photo, C3MF-10344-A.
