crank bolt tightening debate

This is a crucial point. Not only is unknown whether the
timing belt changes were done correctly but it is also unknown
where the parts came from. Therefore, all the provided
"evidence" is worthless and cannot be used in an objective
evaluation.

 

Because no one came forward to help you I will explain it to
you myself. Could be helpful when "educating college
engineering students."

A quantity consists of a value (also called magnitude) and a
unit (also called dimension), for example "4 quarts," or "1
gallon." Here, "4" and "1" are the values and "quarts" and
"gallon" are the units of the quantities. In these examples
the values and the units are different, but they both specify
the same quantity because 4 quarts equal 1 gallon. So, it is
irrelevant in what units a quantity is expressed, but it is
common to choose units that yield easy to handle values -
avoiding very small or very large numbers.

And if you are specific about the "other assertions" I will
help you with those, too.

Now, would you please help me? I don't understand your first
paragraph. But this could be because I am neither a mechanic
nor am I a metallurgist, and I didn't have the benefits of
"materials 101." When rewriting it, please pay particular
attention to the implications of, "the cut of the threads does
not tend to tighten the bolt," and, "The threads are helically
cut on both coarse and fine thread designs, of course, so
back-and-forth vibrating forces will tend to have the same
effect on both." What would be the effects if the threads were
not helically cut, and what bolts would these be?

Very well said.

I just remembered why I hated school. Thanks for the memories.
