To correct vertical angular misalignment, where should shims be placed?

When correcting vertical angular misalignment, shims should ideally be placed at the back or front of the equipment. This practice is essential because shimming in these areas can effectively raise or lower the vertical angle of the equipment, allowing for alignment adjustments.

By placing shims in the back, you can help tilt the machine forward, while shimming in the front allows you to tilt it back, which is crucial for ensuring that the equipment operates smoothly and efficiently. Proper alignment reduces wear and tear on components and minimizes the risk of operational issues, making the placement of shims in the described areas important for maintaining the integrity of the machinery.

Choosing other locations, such as only the left or right side or using shims on all four feet, may not effectively address vertical angular misalignment. This could result in continued misalignment, leading to increased vibration and potential failure of the equipment. Therefore, focusing on the back and front areas is a strategic approach to achieving proper alignment.
