Question

A bent valve spring must be replaced if it has a spring height variance of more than

-0.005 inch
-0.0625 inch
-0.125 inch
-0.025 inch

Answer 1

A bent valve spring should be replaced if it has a spring height variance greater than -0.005 inch.

Step-by-step explanation:

A bent valve spring must be replaced if it has a spring height variance greater than -0.005 inch.

This means that if the spring's height deviates by more than 0.005 inch from the specified height, it needs to be replaced.

For example, if the specified height is 2 inches, a variance of -0.006 inch would require replacement, while a variance of -0.004 inch would not.
