question on 6th gear request...

[Rick McCauley]

I just changed my front sprocket yesterday. I flattened the washer, hit the nut with 90 psi on the impact gun, and off she came. I put the new one on, and made the nut finger tight. I hit it with 100psi and bent the washer over. I don't see how it will ever come loose as long as that washer is on there, and I am sure it is as tight as it was before I took it off. If anyone knows why that would be wrong, please let me know. I do have a question though. I got the JT sprockets. The front sprocket has a different boss on each side. The one side is a circle the same size as the collar around the sprocket shaft. The other side is almost the same diameter as the sprocket itself. I assumed the smaller side should go toward the engine, and the larger side would be for the washer and nut. But I know what assuming can do. Anyone know for sure what JT's intent was on this?

I rode #7 last May going North from Dallas. I think the sign said, "Winding Dangerous Road Next 169 Miles." Not getting the c/s nut tight is a problem. I have found that adding a breaker bar and socket is a minimal addition to my tool roll that I carry--and fore-go the torque wrench when I travel or make a trail side change. Now, that said: I use my torque wrench in the garage to the maximum extent practical. I don't make it a religion to use that torque wrench(s), but probably more than most. Trail maintenance: My breaker bar is the same length as my torque wrench--(you see where this is going), so I have an idea as to how much 'pull' 69-70ftlbs feels like. I initially was not comfortable doing this, but have yet had it go awry. With a breaker bar--I believe another usable rule of thumb is snug plus 1/8 of a turn for field work. I doubt that you could over torque a C/s nut--as the rear brake will slip before you pull to much torque; at least in my experience. On an amusing note, as a MO Ozark prairie rat, we used to refer to that snug plus 1/8 as an "Arkansas torque wrench" or guet-n-tite. shrug. Must be a common nomenclature, as my Marines from WV called it by those names as well. There have been many a bolt twisted off using this technique--as well as misreading a torque wrench! Still, I don't think you will get a C/S sprocket to tight using due care. Oh, it was also sometimes called an Oklahoma torque wrench--depending on the last team to be the Mizzou Tigers, etal. revmaaatin. [Non-text portions of this message have been removed]
