Right motor & Cage but incorrect electrical
I watched the video. Its tricky to remove and replace but I finally got it. The real challenge came when I tried to plug in the power. The old motor had to terminals facing outwards but the new had parallel terminals like a wall outlet.I was to far into the project to give up so I broke apart the old terminal and made a tape like new one. Otherwise the price & delivery were excellent
