The drive coupling wore out

I unscrewed the old coupling and screwed on the new coupling from Partselect.
This was a personal repair job.
However, I am a local Handyman in Northern NJ that does a ton of minor repairs. For all of my appliance part needs I will buy from Partselect.com. They under promised and over delivered! Just incase you dont know what I mean by that statement,,, I ordered the blender part, they told me I would have it in 6-10 days (which was acceptable to me) and I had it in two days... AWESOME job FOLKS!!!!!!!
