I am curious is this a 2/4 pole cpc? and if so i read somewhere that you could make it a six pole with magnets. I just don't remember where i saw it. thanks for the help

I read that too.
you have to use some small rare earth magnets and arrange them on the ring material and let them sit overnight.
some CPC rings are un-magnetized. I have a couple sets that have 2 pole and 4 pole and a third set that are not magnetized at all. Its only that third set that you can do that with unless you have a way to "erase" the 2 or 4 pole version.

cool I will try and magnetize the center rings to be six pole Just for giggles i will make the 6 pole rings closest to the front of the tube.
Do you know which is which 2 / 4 they have white on the tabs and yellow.
I cant remember white is 2 pole and yellow is 4 pole ???
Does that sound correct?

lay one flat , put a piece of paper over it and shake some iron filings on the paper. it should show the magnetic pattern.
old public school trick

Cool. I'd like to see the iron filings. Take a picture for us.

sure no problem
Do you think it would be wise to redo the fields for all the rings?

Threadus resurrectus!
Any luck manually magnetizing the dead ring? I have a set I can pull from a 1208/2 that look just like that pictured, AND I have access to LOTS of ridiculously powerful rare earth magnets. (Not to mention several 800+ Joule magnetizing machines )

I have access to several very specialized magnetizing machines...
My company makes automotive sensors that use magnets and hall-effect (among other) sensors: The magnets we use are typically Neodymium-Iron-Boron ceramic, about 5/16" square and 3/16" thick, and are charged ten at a time (mainly because the LIQUID-COOLED coil takes two minutes to cool off enough for another shot!) Magnetizing ceramics requires a specialized field, created by a specially designed coil, so there really is no such thing as a generic magnetizer.
The CPC magnets will typically be a plastic that is highly loaded with ground ceramic magnetizable powder (such as NiB) and are actually magnetized IN the plastic mold when they are shot... While the plastic is molten a field is applied that concentrates the magnetic filler in the spots where the poles are to reside.
This is why I'm interested to know if anybody has been successful magnetizing a dead ring.
We've got one damn spiffy plastic magnetized-in-place ring that we use, which is actually shaped rather like a CPC ring, with 15 pole pairs.  It's used as a rotary encoder with a hall quadrature counter on a motor-driven product we make.
This is contained within the production "SmartBar" (TM AA&M) sway-bar disconnect that American Axle provides to Jeep.
http://www.aam.com/index.php?s=48 (We are AA&M's tier-two on many products.)
Note that the picture on AA&M's website is of the Proof of Concept piece, which actually uses another actuator I helped create, but which looks NOTHING like the production SmartBar actuator.
--Edit: This site shows the best pic of the production unit that I could find. http://www.wawii.com/powerwagon/LegendaryDodgeRamPowerWagonReturns.htm
The smartbar actuator is the cast aluminum bit partially hidden behind the winch drum.
