prevailing torque nut
I remember reading on some web-page about a countershaft
sprocket nut for the KLR that doesn't need the bent washer.
I recall it was something like a "prevailaing torque"
locknut that had some material machined from it to fit.
Who has those? I need one.

prevailing torque nut
On a similar note - anyone happen to know the size of the countershaft
sprocket nut?

prevailing torque nut
Is a prevailing torque nut a deformed-thread nut? If so, wouldn't it require _more_ torque to give the same clamping power? i.e., if the original required torque is 70 ft-lbs, and the nut provides 20 ft-lbs of resistance, wouldn't you want to tighten to 90 ft-lbs? Or is the main concern just to keep it from loosening?

It depends on how loose the countershaft sprocket is on your countershaft. I usually have to tap sprockets on with a rubber mallet, so all I need is something to keep it from sliding sideways. The high torque is to keep a sprocket that has wiggle room (on a small-end-of-the-tolerance countershaft and big-end-of-tolerance sprocket) from messing up the splines, and working the nut loose in the process. No wiggle room, no need for caveman tightening. Devon>>Is a prevailing torque nut a deformed-thread nut?

prevailing torque nut
Prevailing torque nuts are used in applications where vibration (or
other factors) may cause loss of applied torque during service (y'all
knew that already).
Someone asked if the prevailing torque to drive the nut on the shaft
was subtracted from the torque that generated clamp load. The answer
is yes.
I haven't been inside a KLR transmission, but there may be some (very
good) reason that the KHI engineers are specifying such a high torque
on the c/s sprocket nut. Typically, it would be to provide correct
end load on a bearing, a "stack" of bearings or a shaft. Recall that
KHI changed tranny internals when they changed from the retainer-type
c/s sprocket to the high-torque nut.
I would (and have) use the recommended torque value. I know its a
hassle, but it makes sense.
FWIW, Tom

prevailing torque nut
I am thinking about using the prevailing torque nut,sold by Arrowhead,
on my countershaft sprocket. Any of the members use this instead of
the original nut and washer? Can it be reused numerous times or is it
a one or two time used item? Thanks for any advise. Ken in Katy Tx.

WOW! That's a beauty!
