Which of the following is NOT a step in checking bearings?

The correct answer highlights that bearing inspection does not typically involve air-drying them by spinning with compressed air. This method can actually introduce contaminants into the bearings or cause damage due to the high-speed spin that may not replicate actual operating conditions. Bearings are generally checked for wear through visual inspection, assessed for smooth movement, and lubricated appropriately based on the manufacturer’s specifications prior to reinstallation.

Visual inspection for wear, checking for smooth movement, and lubrication are all integral parts of ensuring that bearings function correctly. Each of these steps enables the technician to identify any potential problems and prepare the bearings for optimal performance.
