Many thanks for this strip-down photo sequence. I used it to help with stripping down the DEC axis of my CG-4 mount (identical except for TWO red washers - step 5) which I found had very little grease at all and what was there was white, rather than black. I didn't have time to strip the RA axis, but intend to do so this weekend. The DEC axis is super smooth and no backlash, having tweaked the tension on the brass worm screw engagement with the worm gear.

Question, though, regarding the use of grease on the outside of the bushing containing the worm gear (see photos step 9 DEC axis and step 8 RA axis). The worm gear and inside the bushing where it rotates on the shaft need greasing, but I think that the outside of the bushing should not be greased where the little plastic clutch grips it, otherwise the axis might slip when it's at extreme angles. I know that what I did before re-assembly was to clean off any grease in that area and my declination clutch locks solidly, but I wasn't sure if it would make any difference. Did you find that there was any slippage? Am I over-thinking it!
