Frigidaire W2 timer

[cardona7]

I've got an Frigidaire W2 washer that is having to be helped through the washing cycles. Knowing nothing about the workings of washers, I'm assuming there's a timer behind the large righthand knob that is not syncing up with the cycling gear. Yes? I tightened down that series of discs/plates under the big knob but apparently didn't get them back in the proper sequence. Are parts available for these old units and if so, where? Diagrams? The serial # is 41 EM 0910.

Thanks.
