first of all great videos....as usual, great info
now a couple things I have come across as well....
as for the indexing.....mine has stopped, and I kind of miss it, the little increments seemed to help during the wash....
I also have a Raytheon model, the indexing tub helped with the rimflo filter ring, its movement helped scoop the lint into little piles, rather than just fill the holes, and filter action stopped......
also, over time, an annoying "squeek" developed from the brake, trying to hold the tub completely still......2 drops of 3n1 oil on the disc caused it to do a minimum index, and kill the noise....
one last thing, as Mike has pointed out, the spin on a large load did not seem to reach top speed for me as well......I stretched the spring about 1/2 inch more tighter, gave a better grip for wash and spin.....this slippage is similar to what I had with the Maytag's, but in this case a 3rd spring was added to correct the excess slippage....this may help you guys as well....
