OD run-out on splines is perfect - no run-out, Zero
OD run-out on Timken surface has +.003 run-out, Bad
It was a new sprocket shaft in the package.
Noot thinks what happened was the surfaces were ground separately,
and they got a shaving on the center after they ground the splines.
The Timken bearing will be shaking and probably destroy itself.
You can't just throw the shafts in and start assembling . . .
You must check run-out on parts during assembly.
You really have to check this stuff,
even if it seems rather mundane.
