What should be done if the taper and bore are not clean before installation?

  1. Installation can proceed without any issues

  2. It may lead to inaccurate drilling

  3. It increases the chance of success

  4. No problems will arise

The correct answer is: It may lead to inaccurate drilling

When the taper and bore are not clean before installation, it can lead to inaccuracies during drilling. Clean surfaces are essential to ensure that components fit tightly and align properly. If there is dirt, debris, or any residue present, it can interfere with the fit and may cause the tools to become misaligned or exert uneven pressure during operation. This misalignment can result in an improper installation, leading to further complications such as vibrations, operational inefficiencies, or premature wear of parts. Hence, clean parts are crucial for accurate drilling and overall successful maintenance or installation operations.
