Great post Ken - thanks for scanning! I'm glad to see such a cool document shared for everyone to enjoy.
I've never known why (nor have I read to see if there were bulletins about this) but does anyone know why they went from the smaller square opening on the original Jet Action agitator circulator column to the larger opening on the later upper cones?
In the parts stash are examples of each below. (If there are more out there - let me know.)
The original square opening was used on the coin-op machines, documented by Robert's original deep action link
HERE, starting in 1962. What is interesting is the original coin-op use of this column also used a revised, stiffer, version of the diaphragm. This means Frigidare was using two versions of the diaphragm at the same time.
If you look at page 11 on the brochure of Ken's, you'll notice they use both the original opening while pouring the detergent, and the revised 7537930 to demonstrate the fabric softener dispenser. I've never seen a 1965 with the early square opening, but always the 7537930 instead. Maybe the original 7529894 was used on the converted 1964 Rollermatics only?
The center column was part of kit 6591882, claiming to replace agitators in 1955 through 1965 J/1966 K series machines.
(Correction - per the 1965 Service Manual, it does indicate 1965 uses a 7529894, but shows the larger square, like the 7537930)
Lastly on the right is the 9956770 Agitator Kit. This example is NIB, and has the later 1-18 style diaphragm, instead of the original hard rubber diaphragm used prior to. IIRC the later pulsator was used on some L and N series washers, but I cannot totally confirm this.
The 9956770 Agitator Kit was later billed as the replacement diaphragm for all 1955 through 1969 Frigidaires by the late 70's/early 80's.
