AAAAARGH!!
Well, after the success with the Maytag and despite hitting another wall with the Dominion, I thought I had nothing to lose by attacking the Inglis again.
I had prepared a diagnosis chart and checklist of possible causes while I was in the UK (Most folks take books to read on planes - I take Whirlpool service documentation... LOL). Anyway, I figured that the agitate solenoid was the number one cause for the Inglis' lack of agitation. I got home, tested the solenoid and glory be - it was indeed 'open'. I slapped on a new solenoid assembly (I had a sparebelieve it or not!) and when I fired up the washer, it agitated, drained, and spun! I was elated, but I thought I should try it again. I got the washer to agitate so I thought I'd try it with some clothes. With just one bathrobe in the machine, the agitation slowed to a crawl. I took the robe out and the washer no longer wanted to agitate. GRRRRRR! I tried adjusting the belt tension, but no luck.
I now think that the original Inglis transmission is shot and that I probably made things a lot worse by swapping narrow-belt components. I think the only logical thing to do now is going to be to salvage the 67 WP Donor tranny and slap it into the Inglis. It would make sense, since the outer tub and baseplate came from that machine anyway! So I am on the hunt for another spin tube and I will make good use of the photos Ben posted for the restoration of his '59 Kenmore...
And that whine you hear is Hubby complaining about the machines strewn all over the basement... LOL
