The use of DAA agitators....
A Dual-Action belt-drive agitator would fit perfectly in this machine, in fact when large capacity machines such as the innards of this 'new' blue machine were made in the mid 70s, WP was still using the standard surgilator in their Large caps. while KM was using the new DA, the Penta-Swirl, and the Penta-Vane.
There are misgivings in many people's minds about WP/KM agitators in standard and large capacity machines. Both capacities use the same transmission from late 1973 forward, and thus agitators are interchangeable between the capacities. The only visible difference is that the top of the agitator is much lower in the lid well of the machine than it is in the standard. The agitator from a 1986 large capacity machine will fit a 1966 standard Lady Kenmore, for example. It might look stupid, but it will fit.
In fact, there were DAAs in all three capacities of belt-drives from the mid-70s forward. The base agitator was the same part, only the auger was different (shorter) on the standard and 24-inch models.
As a rule, all agitators in belt-drives are essentially interchangeable, with the following exceptions:
1) Machines built 1963 or earlier which had the single groove agitator shaft that accomodate ONLY a drive block style agitator. Polypropylene splined agitators cannot be used in these machines unless the agitator shaft or entire transmission is swapped.
2) 1967 - 1973 18lb. Large capacity machines - These use an extra tall agitator shaft which require tall agitators which fit only these machines. These models are rare today, any of which are on my dream list. Standard agitators are about 3 or so inches shorter and don't fit flush to the bottom of the basket. Basically, these machines were built to the scale of the original standard capacity models where the agitator rose 6 or so inches above the water line and into the lid well. When the 1974 large capacity re-design was done, the agitators rise only an inch or two out of the water.
