If the dial reading for shaft misalignment is + .014", what is the actual total (rim) misalignment present?

To determine the actual total (rim) misalignment from a dial reading, it's essential to understand how dial indicators measure misalignment. When a dial indicator gives a reading of +0.014", this measure typically represents the total indicator movement due to misalignment.

In many cases, the readings provided by dial indicators reflect half the total misalignment when they are used to check for alignment in a shaft-to-shaft configuration. Therefore, the reading needs to be doubled to find the total misalignment. However, in this specific context, because the reading is taken at the rim of the shaft, the measurement reflects the overall misalignment directly when indicating how much deviation there is from perfect alignment.

Given that the dial indicator shows +0.014", and considering the design and function of the equipment being measured, the actual total rim misalignment is understood as half of that reading. Thus, the correct value for the total rim misalignment indicated by the test would simply reflect the positive reading, resulting in a total misalignment of +0.007". This outcome arises from the practical application of calibration and measurement methods used in the field.

By breaking it down into the measurement's practical implications, the total rim misalignment is assessed correctly, leading to a clear understanding
