fold down the tab washer leg which stops the tab nut from rotating, then you can tighten tab washer.

only way ive found to do it, is to tighten put back together and check back lash, if still there remove everything and tighten even more. back lash should be checked using a test dial indicator

you remove the pulley by undoing the grub screw located in between the teeth

Ye, that's what my poor PM was trying to explain.
