Question

technician a says that the flywheel runout can be checked with a dial indicator. technician b says that when checking flywheel runout, it is good practice to also check crankshaft end play. who is correct?

○ a. technician a
○ b. technician b
○ c. both technician a and technician b
○ d. neither technician a nor technician b

Explanation:

To determine who is correct, we analyze each technician's statement:

• Technician A: A dial indicator is a standard tool to measure flywheel runout (the amount of wobble or deviation from a perfect circle). This is a valid method.
• Technician B: When checking flywheel runout, crankshaft end play (axial movement of the crankshaft) can affect the measurement. Checking end play ensures accurate runout results, so this is good practice.

Both statements are correct.

Answer:

c. Both Technician A and Technician B
