Where should shims be placed to correct vertical offset misalignment of a drive unit?

Shimming is a crucial method used to correct misalignment in machinery, ensuring that the drive unit operates efficiently and safely. When addressing vertical offset misalignment, the optimal approach is to place shims under all four feet of the drive unit. This evenly distributes the load and compensates for the misalignment across the entire unit, leading to a more stable and aligned setup.

By shimming all four feet, you ensure that any adjustments made to bring the drive unit level are uniform, reducing the likelihood of stress that could result from uneven support. This helps improve the performance of the system and minimizes wear and tear on both the drive unit and the components it interacts with. Addressing all four feet allows for not only correction of the vertical alignment but also offers a balanced support structure, which is essential for the longevity and efficiency of the machinery.

Focusing on just the front or back feet, or only one side, would not adequately address the entire unit's alignment needs, potentially leading to further issues with stability and alignment in the long term. Therefore, applying shims under all four feet is the best practice for correcting vertical offset misalignment effectively.
