What reading level is Stevens Mechanical Catechism book?
To quickly assess the difficulty of the text, read a short excerpt:
Q. Can you tell whether a crank pin is out of square?
A. Yes.
Q. In what way?
A. The slightest variation can be found by a good spirit level, which is used as follows: First, disconnect the main rod from the crosshead, then key the rod to the crank pin so the rod can turn without moving sidewise ; then place the rod in a position to move easily as the crank is turned.
120 QUESTIONS AND ANSWERS Fasten a spirit level to the rod with a clamp in line with the shaft (right angles with rod). When the... crank is turned the bulb in level should not change. If it does the pin is not square with disc nor parallel with shaft.
Q. Does it make any difference if the shaft is not level when testing crank pin?
A. No; the point that the bulb in the spirit level moves to, when clamped to the rod, is the point where it should stay the full revolution.
Q. If the crank pin is not properly set, how will the bulb show?
A. It would move, and the more the pin is out of square, the more the bulb will move.
