Which of the following should be used to check the runout of a resurfaced flywheel after reinstalling it on the crankshaft?

A. Dial indicator
B. Feeler gauge
C. Micrometer
D. Torque wrench

Answer :

Final answer:

The correct answer is a) Dial indicator. The correct tool for checking the runout of a resurfaced flywheel is a dial indicator, which accurately measures small displacements necessary for ensuring the flywheel's uniform rotation.

Explanation:

The correct answer is a) Dial indicator. The correct tool to use to check the runout of a resurfaced flywheel after reinstalling it on the crankshaft is a dial indicator. A dial indicator measures small distances or displacements with a high degree of accuracy, which is essential when assessing the runout—or the degree of deviation from a perfect circular rotation—of a flywheel. It is vital for the flywheel to maintain uniform rotation because variations can lead to issues with clutch engagement, causing vibrations and premature wear. The other tools listed, such as a feeler gauge, micrometer, or torque wrench, each serve different measurement or application purposes and would not be suitable for this specific task.
