Hunter DSP9200 Series - CenteringCheck Procedure

Shaft Spacers
The shaft spacer can be used to make the cone contact the hub bore more firmly.
For example, one cone size is too small because the captivated spring is not
pressing the cone against the inner wheel opening, but the next larger cone size is
too large and will not fit the opening. Use the smaller cone size, with the spacer, to
extend the captivated spring and hold the smaller mounting cone against the wheel
opening with greater pressure.

If centering of the assembly repeats balance weight magnitude and phase angle to
within programmed limits, the assembly is assumed to be centered. The display
momentarily flashes “PASS,” then shows correction weights.
If centering of the assembly does not repeat balance weight magnitude and phase
angle to within programmed limits, the assembly is likely not centered. The display
momentarily flashes “FAIL” then shows “---” instead of weights. Check wheel to
adaptor fitment and centering. Retry.
