oil bellows redundant, so???
For a few years the 1-18s were made without the oil bellows as it was thought to be redundant protection. Do I understand that correctly?
If the idea is to keep dribbles from finding their way into the agitator shaft bearing if the water bellows fails, isn't there an alternative or two?
I thought there was a relief port to atmosphere, a drain hole, between the water bellows and the oil bellows....so if the water bellows leaks, the water finds it's way out of there thru the drain hole. with our without the oil bellows it will be draining out..Right?
So, put a sleeve in the place of the oil bellows just high enough and fitting close enough to the agitator shaft to discourage water flow into the bearing. Not perfect but not horribly bad. eh?
2. I know this is silly, but why not use almost any neophrene sleeve material, just let it crinkle instead of bellow? I can't say what fatigue life a sleeve would have, but I bet someone could run a test quick enough. I'm thinking about things like dishwashing glove fingers or balloons, or bellows from machinery...
that's all. just my 2 cents worth.
