Answer

b. Technician B Explanation 1. Understand the purpose of each measurement tool A dial indicator is typically used for measuring small distances or variations in position, such as checking runout or endplay. It is not commonly used for measuring piston to bore clearance. A feeler gauge, on the other hand, is used to measure gaps or clearances, such as rod side clearance. 2. Evaluate Technician A's statement Technician A suggests using a dial indicator to check piston to bore clearance. This is not the standard practice, as piston to bore clearance is usually measured with a micrometer and bore gauge. 3. Evaluate Technician B's statement Technician B suggests using a feeler gauge to check rod side clearance. This is correct, as feeler gauges are appropriate tools for measuring the gap between components like connecting rods. 4. Determine who is correct Based on the evaluation, Technician B is correct in their method for checking rod side clearance.
