SSV housing/gear/screw/cover design change notes updated to be a little clearer on the sizing problem. See the page in our support site:

We used to have this page laid out with info for each model but it was too confusing, so the schematic pdfs have been revised for each reel to make that reel models notes clearer. There are links below to each model's part section and it's revised schematic. Schematics are also in each reels parts section near the top.
So all of the updated schematics are now linked in the above design change page, as well as in the reel parts sections for each model.
