It is what actually makes the omni WORK. without them its nearly impossible to find a good adjustment to hold the throttle, stop the omni from loosening with vibration, but still be able to rotate it when you need to AND be able to turn the omni with just your thumb. Took over 2 months and literally hundreds of combinations of spring rates, stack configurations, sizes, thicknesses and geometry to get it right.
Well thank god you used Brazilian bellevilles, and did not use American belleville washers!!!!
My first thought was "why didn't he just put a spring in there?"........and my second thought.......after a couple of Scotch's was........."I should be able to save some weight and get rid of some of these washers!"................remember............that was after imbibing in some fine 12 year old...........Scotch, that is!!
If I had been able to see the washers for what they are, I would have recognized the bellevilles............I've never seen them that small before!
You might want to include a warning on your instruction sheet to dissuade foolish individuals from removing the adjuster screw. If those bellevilles are not stacked correctly, you will not have any spring tension. EDIT........finally had a look at the instruction sheet, and see you did put a warning on there
Once again............great product at a reasonable price!
