I currently own the dryer ...washer wanted BTW
And I just replaced both the blower belt and the drum drive belt which is (77)inches long
The correct part #'s for these are
Blower= y312512
And drum belt= y313328 which most list as discontinued Hwvr WHIRLPOOL#770H4
is the properly fitting replacement ..I INCLUDED INSTALL INSTRUCTIONS FOR DRIVE BELT @AMAZON TOO and I got amazon to sell Both separately . I AM LOOKING FOR THE MATCHING WASHER OR A SET FOR PURCHASE ..ANYBODY?
