Question on 223" double-sheave crank pulley

Hope I have the right forum now; thanks to the member who alerted me….

Question on 223" double-sheave crank pulley:

Hello, first time poster to this forum (hope I'm in the right place..)

I am looking for a way to install power-steering on a '59 F-100, with 223" motor. All the parts (PSP, box, etc.) are available, except pulleys for the crank and WP. By far the hardest challenge - so far - is finding a double-sheave crank pulley, to run a separate belt to the PSP.

There seems to be two possible, "factory", ways, and both are made of unobtainium. "One way" - it seems - is to find the incredibly rare factory double-sheave pulley/balancer combination (one integrated casting). The only one I can find, after calling around for two weeks, is $550.

The "other way" (also factory I believe) is to find the (also super rare) factory bolt-on "outer sheave" - a single-sheave pulley that bolts up to the existing cast pulley/balancer (making a total of two sheaves, then). The "bolt-up pulley" uses the large central crank pulley bolt, and two smaller bolts on little ears. This p/n for this "outer pulley" (I believe) is C1AE6321-C.

Other than that, I am coming up with nada, after weeks of looking/asking. One person said use just one belt, for all 4 pulleys (WP, crank, gen., PSP), but the problem with this is that the WP will have SO little surface-area in contact between the belt and it's pulley (significantly less than 1/4 of a cir***ference), and my experience is that all engine accessories should have *at least* 1/3 of the cir***ference of each pulley engaged with the belt; otherwise, you will have slipping and burning of the belt due to inadequate contact between the two, as well as not being able to drive the accessory properly.

Does anyone out there have experience with this challenge? Does anyone have another suggestion? Anyone know where to find the bolt-on outer sheave? (I have tried about 10 old-Ford places around the country…) Any new ideas would be much appreciated.

Thanks !!

 

I have been pondering this myself for a harmonic balancer installation on a Dodge poly. It sounds like the bolt on pulley could be fabricated fron say a skinny inline six pulley. A back plate could be water jet cut with the pattern and welded into a different sectioned pulley. I don't know how practical all this is due to warping, etc. just a thought.

 

Yep, I would add a pulley to the crank. Find a water pump pulley with a smallish hub, flip it around and adapt it to the balancer. May require some minor machining of one or both.
