I noticed in your attached picture
a solid aluminum tube feeding the redrive. Please check this often, and
consider supporting the tube in mid span to avoid the possibility of fatigue
cracking from (the 'non-existant') vibration.
I have basically
the same setup. I
put a ‘snubber’ at the re-drive plate.

Good advice, the
same setup (as Al's) has worked on mine for 1600+
hours.
