I now have the entire thing apart, minus the wringer head. All the legs off and wheels off and apart. I am trying to remove all the rust and grease from everything.
I changed out my citric acid with vinegar bucket so I could have fresh cleaning solution. It was black from cleaning all the old parts, and had the belt guard and worm wheel sitting in it for a month or so during the break in the project. Explains why they scrubbed clean very easily. Even the old paint came off!
I have also decided to just buy a new center plate with agitator shaft assembly from Mark. He said it would be around $120, so not too bad. It is brand new old stock, still in the box! That and the other parts from him will be ordered on Monday.
Until they arrive, I have a lot of sanding of the chassis and the legs to do!
I think for the drive tubes, and a couple other greasy parts, I will wash with plain water and dawn dish soap to cut through the grease. Maybe I can figure some way to spray inside the tubes to take out the old grease. I cant use vinegar or citric acid solution on them as it rusts metal within 10 minutes if the object isnt completely submerged, and I have no way to scrub the inside. It removes rust very easily though, if you scrub it right when it comes out of the solution.
So happy to have things moving along again!
