Maytag Modell 30 wringer handle

[fallgirl]

I just recently bought a Maytag model 30 wringer washer and I tried out the wringer and noticed the handle is a little wobbley and when I engage it, it will work but then it seems to slip and the handle vibrates and then not work until you mess with handle again. Trying to figure out how to fix or if I just need to buy a whole new wringer head? I'm trying to restore this and it's the first time doing this for me. Also have a leak and need a drain hose gasket and I'm missing the cover for the index plate and also it needs the rubber cap for drain nozzle. Can anybody give me some advice on any of this? Thanks!
