well done
in getting yourself a hoovermatic and also welcome to the club, sorry for being a bit late into this thread and your previous one, ive been full into the vintage christmas lights the past few weeks and your helping me to get back to the washers again.
I'm in agreement with the advice from steve and ozzie, I don't know how hands on you are with repairs, but your obviously up for the challange. Just tackle one component or problem at a time, you can soon see how things are assembled and how to dismantle them. As Steve siad the knobs are held underneath with circlips, with a a pair of long nosed pliers you shouldnt have too much trouble getting them off. If you want a couple of knobs I have a few spares, though they are pattern ones and a little darker than the originals, drop me an email if you want them.
Also if no one else has mentioned it it would be well worth, greasing the pulsator bearing. Follow steves advice for the pump, also if you can get the pulley off, take the pump impellor out and clean any lint build up around the shaft and grease the bearing up and reassemble, that will help the pump run more reliably. I also like to grease up the valve shaft as well, just to make the change from wash/spin to empty tub smoother, but you can do go on and on depending how fanactical you want to get.
Sorry but I don't have much in the way of service notes for these twin tubs, but I think we've covered all you need for the moment.
But the main thing is to enjoy it and ask away if you have any questions.
All the best, look forward to some photos
