Anyways I thought I would add this...
I have been cleaning the worm gear itself... I could feel litel bumps with my fingure nail and say this if you are cleaning one it will surprise you how hard it is to clean out all the gunk..and on intial inspection after the greese had ben removed it semed clean.. it took hours to really clean it.. I found like a very small thread wapped around only after cleaning with a car polish wax and carburetor cleaning fluid..all I can think is a small spider has got in there and the web wound around the worm.. and maybe the small bumps were sqaushed prey once in his web... but my point is it is not as clean as one thinks ..Ihave inspected every inch of the track and the "corona" indents and now clean they look rather good.. I have not lapped the gears and will reassmeble the mount without greese as I think there is an advantage to be gained by using a very light machine oil..I plan drillng a hole to dap a little oil sparingly as it is needed... maybe spray the inside to keep out insects as well...
For anyone pulling down their mount I found the only confusing thing was how the conical bearing was held in..and so you know there is a flat washer that screws in in front and holds it in place. I nearly amde the mistake of thinking the bearing only needed to be pressed out..lucky I did not get out the flywheel puller...
I may even reassemble without any oil to locate high spots in the gear system but I feel short of a lap job the gears are meshing rather well all the small indications of wear show all gears are ok but with greese all the high spots may not have shown up...
