Technician A says that you must place the dial indicator base on the drive shaft and place the indicator tip on the bearing cap.

Technician B says that you can use a dial indicator to check for excessive joint movement by forcing the yokes back and forth in opposite directions.

Which technician is correct?

A. Technician A
B. Technician B
C. Both Technician A and B
D. Neither Technician A nor B

Answer :

Final answer:

Both Technician A and Technian B are correct in their respective approaches to using a dial indicator. Technician A's method is suitable for checking the bearing itself, while Technician B's method is valid for assessing joint movement. Therefore, the correct answer is C) Both Technician A and B.


Explanation:

Evaluating Technicians A and B

In this scenario, we need to assess the statements made by Technician A and Technician B regarding the use of a dial indicator for checking bearing movement and joint movement.

Technician A's Method

Technician A suggests placing the dial indicator base on the drive shaft with the indicator tip on the bearing cap. This method is typically used for measuring the axial runout of a shaft and can help identify misalignments or excessive play in the bearing. This approach is effective for diagnosing issues directly related to the bearing itself.

Technician B's Method

On the other hand, Technician B indicates that the dial indicator can be employed to assess excessive joint movement by forcing the yokes back and forth in opposite directions. This method is indeed a valid way to determine any looseness or play in the joints, potentially indicating wear or damage.

Correct Answer

Since both technicians present valid methods for different diagnostic purposes, the correct answer is C) Both Technician A and B. Each method serves as a practical application of the dial indicator for specific measurements in mechanical systems.
