CSX2201 and later charging system components

Related comments. If somebody commercially does the sheave and fans that leaves only the COBRA lettered fan belt unavailable alternator wise.

Alternator mounts and adjustment arms are sold commercially by a forum member.

AMK Products® has the special length Ford specification bolt and thick hardened flat washer used for the adjustment slide.

COBRA lettered fan belts for CSX2201 and later cars have been made by several restorations shops for cars they have done but I don’t think any of them sell them commercially. To have complete coverage they would have to have stamps to do several different manufacturing dates.

We've looked at doing the belt lettering and will probably pursue that when needed. The process we would do is to silk screen the belts.

Something I've seen from time to time on original and replica Cobras using the DST alt pulley is the wrong width belt. Correct if I'm wrong Dan but the original belt is .390" wide I believe. It fits in the pulley nicely as well as the correct vintage water pump and crankshaft pulley. A wider belt rides higher in the pulley and runs the risk of coming out. Just something to keep in mind.

Original belts are narrow ones. They were tough as I know of original cars still using them five decades later.

Tossing belts is usually an indication that one of the engine sheaves is the wrong one. The CSX2201 and later Cobra system was designed around 1963 Ford 260/289 sheaves for crankshaft and water pump applications. 1963-64 engines use the same parts. Starting roughly August 1964 the new “1965 model” engines got new sheaves with different groove locations relative to the mounting hubs. See Bob Mannel’s book.

Mixing 1965 sheaves with a CSX2201 alternator system will most likely lead to fan belt issues. When I bought my red car somebody had installed 1965 and later water pump sheave. The alignment with the original alternator and crankshaft sheave were quite visibly off and the belt had to be super tight to keep it from walking off the incorrect sheave. Super tight fan belts are not a good idea. The purchase of a good used 1963-64 water pump sheave solved that problem.

The original white ink stamping (yes, rubber stamp method) was very fragile. Time, fluid leaks, careless handling, pressure washing, or chemical cleaning all removed the text. Original belts are not ultra rare but ones with text that you can read are. Production and service parts were dated. The latest date I know of for a service part was in the fall of 1966.

Restorers have no problem getting stamps made but finding high performance, narrow width, and unmarked belts is not just an any parts store search.

For belts I suggest contacting Kevin Marti at Marti Auto Works. He does the "FoMoCo" stamped/dated belts for many Ford applications and used to make them for my business. He had/has a source for the correct width and does what I assume is a hot stamp process that embeds the text into the belt surface. I had him make about twenty different belt applications for 61-66 Thunderbirds and the belt cores were genuine Motorcraft belts so no worries about belt quality.

And I neglected to post the pricing information on the plug/harness setup....they are $47.95 each and shipping via USPS Priority is $7.50 for up to 5 plugs.

I will talk to the potential pulley manufacturer this week.

A pile 'o packages stuffed with these harnesses went out this AM. I would appreciate comments on them when they arrive.

Now on to the pulley/fan project............

Rick, alternator harness's arrived today and they are beautifully done. Thanks so much. Now on to the Fan/pulley.
