Bbearing wear is 0.010 inch
Cbearing wear is 0.002 inch
Doil clearance has increased 0.010 inch
AI Explanation
The correct answer is C) bearing wear is 0.002 inch. The reason for this is that the original bridge gage reading for the reduction gear bearing was 0.008 inches. A year later, the reading increased to 0.010 inches. This indicates that the bearing has worn by the difference between the two readings, which is 0.002 inches. The other options are incorrect because: A) Oil clearance is the space between the bearing and the shaft, not the wear on the bearing itself. B) The bearing wear is 0.002 inch, not 0.010 inch. D) The oil clearance has increased by 0.002 inch, not 0.010 inch.
