My brain was not registering what you had posted. The Losmandy G11's clutches are not at the adjustment knob end of the axles, the clutches are at the top of the assembly near the DEC axis and near the saddle clamp directly under the large worm wheels so no packing will keep the clutches clean. These lower thrust bearings are a maybe a 10 minute job each to degrease, lube and reassemble. I would not bother to try to make something to keep out dust for a few reasons but mostly because as an imager I don't want to make any changes what could influence my mount's tracking error. For purely visual use in a dusty environment where the mount is left outdoors for the observing season maybe but if you take the mount indoors for the winter this is the perfect time to disassemble and clean the mount in preparation for the next season. Spend you time on other stuff, you know like observing.?
There is another option that would resolve any wavy spring washer OD clearance issues if you feel you have to use the wavy spring washer in the original Losmandy position. Just add one additional thicker thrust bearing race to the side of the thrust bearing stack to better support the bearing race and to raise the thrust bearing assembly stack height to the point where the wavy washer OD is outside the mount body bearing cavity. These are cheap from McMaster Carr but the shipping charges are insulting.?
Here is the??for the thicker bearing race washer you can use to increase the thrust bearing stack height.?Alternately?you can also stack one or more of the standard thickness bearing race washers, McMaster Carr?.?
