I finally had the guts to disassemble my avx, clean it, regrease it and replace it's bearings with new better ones. One of the bearings I've changed is the radial bearing; i replaced it with a tapered one just like RocketSparrow did here .
I think I got everything right except I'm confused about one thing. A nylon washer was used between the old radial bearing and the ring gear. Following RocketSparrow's guide, it seems that he did not use a washer between the new tapered bearing and the ring gear. Now here's my issue with/out the washer with the new bearing:
1- If I use the washer, I can hear a sound like something's rubbing on something while slewing the mount although i did experiment with both very little grease and a more generous amount of good quality grease on the washer.
2- If I remove the washer, the axis becomes extremely smooth and exactly what you'd expect from a hypertune and the rubbing sound disappears; however, the ring gear starts to slip downwards (towards the bearing). So it seems to me that the washer is holding the ring gear and keeping it from slipping downwards. I've attached some images to clear this further. The images used are from RocketSparrow's website with added markings from myself.
Can anyone with some experience in Hypertuning the AVX care to clear this thing up for me? should i use the washer or not? Is it fine if the ring gear slips downwards? What can i do to stop the ring gear from slipping while getting that smooth motion I got without using the washer.
Any help would be appreciated.
