washer will not spin, is there a belt that operates this?
There is, but usually it is the thrust bearing assembly that causes it not to spin.
Here is a Maytag tech bulletin on the parts

and here is a service bulletin for models like yours which will show you how to open it up and check the belt and other areas.
