Dave, There is no reason to throw down your toys in this situation. If you are not willing to put forth some effort, you are not going to have much success with vintage appliances. We who have been doing this for decades figure that each new acquisition is going to need work and some tracking down of parts. That is just the nature of old appliances. As someone said about used cars, "Nobody gets rid of a car because it is working too well." The same goes for appliances. Several of us have given you good advice on how to go about getting the pump and other parts. Yes, the dryer is not the most durable machine ever made, but if you are using it by yourself, it will not have the heavy use of a family so it will work for a while and after that, there are other 24" dryers you can put on top of the washer. I can sense your frustration, but channel that negative energy into some positive effort and you will have the machines restored before you know it. We are here for support and information, so you would not be by yourself in your efforts.
Have a better day. Don't let these little machines best you.
