Is this common problem?

New bushings ("bearings") and other small parts already from Brewers.
New fork rod. Notice the picture does't show a "jam" nut on it.
I've got one on mine to prevent the "adjusting nut" from turning out of position.
Was that my idea or did it come with one?
Probably my idea.

Jam nut = Good idea.
I thought there was a nut on both sides of the clutch fork. I'm gonna have to take a look now.
