Some of you may recall I was chasing azimuth play and notchy tracking on my 1 year old Skywatcher 10" collapsible
I got it apart and found the 13 inch roller bearing had pressed sharp indentations into the 2 large metal plates that it is sandwiched in between.
I contacted Skywatcher and they replied it would take at least 60 days to get what I need......
I went to the hardware store and purchased a 12" lazy Susan bearing, read some "How too's" and have come to the conclusion my mount is a bit different.
Pic 5 is the top side of the base. The bearing is between those 2 metal discs ( you obviously can only see 1).
Pic 4 I'll call the hub. It bolts through the base and holds the bearing in place.
Pic 3 is the hub assembled into the base.
Pic 2 is the ring gear and the large washer above it. This is held to the hub with a stack of washers, 2 dished washers and a nut that adjusts the clutch.
Pic 1 is 3 feet that are screwed to the upper portion of the mount. These 3 feet sit directly on the outside diameter of the bearing.
The diameter if my new bearing is only 10.5" compared to the original 13". I would have to relocate these feet or find a bearing with the proper diameter.
Thickness also comes into play. If I discard the old bearing the hub will sit that much lower in the base. This would increase the distance between the ring gear and worm gear.
That coupled with the thicker bearing is causing me fits!
Any suggestions?
Thanks!
