I am looking for a picture or parts manual that shows the drive hook up for the serrated bushing how it mounts to the main drive mechanism. On the one I just bought, the serrated bushing is on it but it 'slops" around in a 2" hole in the drive plate. Looks like I'm missing a bearing or another mounting part?? I can send a picture if that helps.

Ok.. mine does not have the flex cutout and thru bolt to tighten and secure the serrated bushing. So it is either very worn or it had a bushing. Anyway this helped and I should get this running shortly. Again, thank you...

The picture doesn’t show serrated bushing but you could have one in yours
