Just for info, I made up packers from .5mm alloy sheet yesterday and fitted them up, taking the chance to inspect the worm and ring gears on the dec axis while I was at it. They seem to be somewhat better assembles than the EQ6 at least in my case so I did not strip down the gear itself on the RA axis.
The packers increase the spacing of the mount a little but the aux encoders still work properly so I am going to leave it that way. I decided to make the packers up and fit them along with the now compressed clutch discs as I reckon if I fitted new ones it would happen again sooner or later.
Both axis now lock up nicely and driver properly, I took the opportunity to set the depth of the worm a bit better and reduce the backlash that was present in the RA axis prior. Hopefully a star test this weekend, with the moon more or less full there wont be any pressure to be imaging so I can just work away at testing things.
