Thank you!!
Thank you so much, Dave! I'm not sure what the hole on the separator is. Peter (peteski) had an Admiral brochure that attempted to explain the operation, but I think it was a lot of illustration and not much substance on WCI's part. I didn't dismantle it to see how it really was supposed to work. I believe water was infused by the pump, heavier soil was supposed to fall out by gravity, and clean water could exit the top port, leaving the yuck behind, but that's odd because I'm not sure why you'd want to bleed wash pressure out into the tank, rather than sending clean water up to the arm.
Of course, no clean water ever reached the arm anyway ;-), so maybe it was moot.
The olive-pit port was the wash pump, wherein all broken glass and foreign objects were automatically flushed to the wash arms for easy removal! ;-) Once the arms filled up with enough vanes broken off the wash impeller, and the wobbling impeller stack compromised the carbon-porcelain seal, it was time for a pump seal kit.
Gary, I love the story of $0.25 to $5 D&Ms. I seldom see them for less than $25 these days! I also love the idea of padding them to make them quiet--LOL!
I found that the later units with the black, two-piece sump (early-eighties, but before the dreaded soil-separator) were VERY easy to service. The ones with the porthole at the bottom, with its ring of bolts, were not so much.
