We are checking crankshaft endplay with a dial indicator and get a reading of 0.005”.  The specification reads 0.003" + 0.001" endplay.  Is the crankshaft endplay within spec?  If not, how far out of spec?

Solution:

The acceptable range is as follows:
0.003" + 0.001" = 0.004"
0.003" – 0.001" = 0.002"
0.002" < endplay < 0.004"

A reading of 0.005" is out of spec by (0.005" – 0.004") = 0.001".
