[QUOTE="greg brillus, post: 52819, member: 597"] Perhaps one issue is that the Air wrench you talk of is not tightening the nut as much as you think. Put the gearbox in top gear, place a piece of broomstick through the rear spokes and swingarm, and tighten with a torque wrench to 65 Ft lbs. If the spring that Bruce and Norman talk of is missing this will not help, even so the nut should not come undone that easily. Almost as if something else is not right.....When the nut is tight, how much can you move the C 13 carrier in and out....? this with the C 19 thrust washer in place. If no clearance exists this could undo the C 20 nut. Need about 0.010 to be ideal. The inner face of the nut actually tightens on the outer splined face of the C 3 shoe carrier, and some have a bonded sealing washer in this recess.....if this is missing, the nut could be tightening up on the mainshaft only and not the C 3 face. So you need to check a few more items to see what is causing the issue...........Greg. [/QUOTE]
