Wheel Build Labor at 21% wheel setup and rework allowance: a worked example

Push wheel setup and rework allowance up to 21% and the picture changes. This example computes every intermediate figure at that operating point. a production or service shop needs to estimate whether wheel build work fits the available shift labor

The inputs for this scenario

  • Wheels to lace, tension, and true: 240 wheels (unchanged)
  • Wheel build completion rate: 6 wheels / hr (unchanged)
  • Wheel setup and rework allowance: 21 % (raised for this scenario; the documented default is 18)

Working through the calculation

  • Applying the documented formula (Base wheel build time = wheels to lace, tension, and true รท wheel build completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 48.4 hr for required wheel build labor, the number this scenario is built around.
  • At this operating point the engine returns 40 hr for base wheel build time.
  • At this operating point the engine returns 21 % for wheel setup and rework allowance.
  • At this operating point the engine returns 6 wheels / hr for wheel build completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where wheel setup and rework allowance sits at 18% and the headline result is 47.2 hr, this scenario comes in 2.54% above the baseline at 48.4 hr.
  • It computes required wheel build labor hours by dividing wheel count by build rate, then inflating it by a setup and rework allowance. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required wheel build labor: 48.4 hr (headline result)
  • Base wheel build time: 40 hr
  • Wheel setup and rework allowance: 21 %
  • Wheel build completion rate: 6 wheels / hr
