Question

A says that piston ring grooves should be cleaned using a file.

B says to position a feeler gauge between each ring and the ring groove to measure the ring groove clearance

-A
-B
-Both
-Neither

Answer 1

When cleaning piston ring grooves, do not use a file. Use a ring groove cleaner instead. To measure the ring groove clearance, use a feeler gauge.

Step-by-step explanation:

When cleaning piston ring grooves, it is not recommended to use a file. Using a file can damage the grooves and affect the proper function of the piston rings. Instead, a proper cleaning tool such as a ring groove cleaner should be used.

To measure the ring groove clearance, a feeler gauge is commonly used. The feeler gauge is positioned between each ring and the ring groove to determine the clearance. This helps ensure that the rings are properly seated in the grooves and functioning correctly.

Therefore, in this case, B is correct. Positioning a feeler gauge is the appropriate method for measuring ring groove clearance.
