When replacing ball bearings on an electric motor shaft, you should _______________.

Aapply even pressure to the outer race
Bapply pressure evenly to both the inner and outer races
Capply even force to the inner race
Dtap the outer race with a mallet
AI Explanation

The correct answer is C) apply even force to the inner race. When replacing ball bearings on an electric motor shaft, you should apply even force to the inner race to properly install the new bearing. This allows the inner race to seat correctly on the shaft and ensures the bearing is properly aligned. Applying even pressure to the outer race (A) or both the inner and outer races (B) can damage the bearing and cause misalignment. Tapping the outer race with a mallet (D) can also damage the bearing and is not the recommended procedure.
