What is the first step in the process of bearing replacement?

1. Install the new bearing

2. Remove the old bearing

3. Check for alignment issues

4. Apply lubricant

The correct answer is: Remove the old bearing

The first step in the process of bearing replacement is to remove the old bearing. Properly starting with the removal of the old bearing is crucial, as it allows for the inspection of any underlying issues that may have contributed to bearing failure, such as misalignment, excessive wear, or contamination. Once the old bearing is removed, you can conduct checks on the shaft and housing for any damage or irregularities that need to be addressed before installing the new bearing. This ensures that the new bearing will function correctly and helps prevent premature failure. After the old bearing is removed and any necessary repairs or adjustments are made, the next steps would involve cleaning the area, checking alignment, applying lubricant, and finally installing the new bearing in the correct position.
