Question

When measuring main bearing bores,

A says the vertical measurement should not be larger than any of the other.
B says out-of-round measurements less than 0.001 inch are acceptable if the vertical reading is not the largest

-A
-B
-Both
-Neither

Answer 1

Both A and B are correct.

Step-by-step explanation:

In the context of measuring main bearing bores, A says that the vertical measurement should not be larger than any of the others, while B says that out-of-round measurements less than 0.001 inch are acceptable if the vertical reading is not the largest. Both A and B are correct.

When measuring main bearing bores, it is important for the vertical measurement to be within the range of the other measurements. This ensures that the bore is uniform and not distorted. Additionally, when measuring out-of-roundness, a tolerance of less than 0.001 inch is acceptable as long as the vertical reading is not the largest.
