You washer does not need to be scrapped unless you want it to be.
There are lots of motors out there for your 1977 80 series machine. My go-to source would be eBay.
Let me give you a couple search tips:
If you want new, there are many new in box Whirlpool/FSP motors available, but being new, most of these are varyingly expensive, depending on what each seller wants for them, from full retail and down from there. The Whirlpool part number is 285222. Search that, you will find many results. This motor comes with a capacitor (as did your original motor) which must be installed on the motor, then you will have to install the old motor mounting brackets onto the new motor. You will also have to swap the motor pulley.
If you are ok with used (the rest of your machine is by now very used) then when you search 285222 some sellers will list used motors under this part number. Look those over carefully. I have bought them everywhere from $14.95 and up. Shipping is not cheap because these motors are heavy.
Finally, search part number 357822. This is the late model part number for two speed square capacitor start motors made by Emerson. They were what MOSTproduction was shipped with in the late 70s through the end of the belt drives.
I will do these exact searches for you now. If I find something interesting, I will report back.
