Answer :
Final answer:
The runout of a crankshaft that has dial indicator readings of plus .002 inch and minus .003 inch would be .005 inch.
Explanation:
In the context of engine mechanics, the term 'runout' refers to the measure of how much a shaft or axle deviates from an ideal straight rotation. In considering crankshaft runout, we typically get two readings: a positive one and a negative one. If your crankshaft runout readings on the dial indicator are plus .002 inch and minus .003 inch, you sum these absolute values to find the total runout. The total runout would then be .002 inches + .003 inches = .005 inches. So, the runout is .005 inch.
