Hi Art,
I guess you could call it a slip ring as I don't remember it having a bunch of segments either!
It might be in two sections of half or rings with a brush for each. I don't know what constitutes the term, commutator, except using Direct Current.
I think I have a couple laying around in pieces in a box somewhere but I'm not where I can dig them up to see.
I had thought about turning it in my lathe to actually "skin it" a wee bit as to take off only the groove or grooves. Mine were pretty deep and polishing was not an option. It been a long time ago for this ole' boy!
As I remember I would have to make a slip on fixture to hold the end for stability. It doesn't have a center hole in the end of the shaft.
I imagine it could be repaired like an alternator's rotor if one was very desperate.
I also looked into getting it reassembled too! It would be a bear with magnets pulling on things.
The brush setup in there is very tiny! It would take several attempts to get a holding combination to slip it back in there correctly.
Again the brushes are very tiny and the unit would have very used brushes in it!
So altogether, I couldn't raise enough excitement in it for me to accept the challenge and for it to be a very "time worthy" project.
I have collected several of them over the years and they those will probably last me the rest of my life.
It's Funny, I did the same thing for speedometer clusters until I got tired of tearing two apart to swap out gears for the odometers. Trying keep mileages semi close to actual mileage on the cars got to be troublesome too!
I finally collected enough clusters that's when the challenge was good enough to make new ones, out of Delrin material, I made a stick of them in one setup.
I parted them off singularly to a thicker thickness and diameter. I also had to keep the tolerance of the center hole so to fit the pin on the other gear nicely.
I managed to remove some excessive play to the ring gear in the process so it helps support the counterweighted planet gear.
If I can improve something that raises the level of challenge too!
The IAC is very limited in options from my point of view. It gets a lot of hours of operation as it is!
The internal return spring on LH 2.4's made them better though so they took their best shot already!
I gave Dave Stevens a thumbs up for thinking of tricks and a lot deeper than I have!
