In alignment work, which component is typically shimmed?

• A. Base plate
• B. Motor
• C. Coupling
• D. Gearbox

Answer: (B)

In alignment work, the motor is typically shimmed to ensure proper alignment with the driven equipment, such as a pump or compressor. Shimmed adjustments are necessary to correct any misalignment that may lead to excessive wear, vibration, or operational inefficiencies. When a motor is misaligned, it can create undue stress on both the motor and the driven equipment, leading to potential failure of components. Shimming the motor allows for precise adjustments to be made vertically or horizontally, which helps in achieving the optimal angular and parallel alignment with the coupling or the gearbox it is connected to. By shimming, technicians can ensure that the motor shaft and the driven equipment's shaft are perfectly aligned, minimizing the risk of operational problems and extending the lifespan of the machinery. In contrast, while other components such as base plates, couplings, and gearboxes can play roles in the alignment process, shimming is most directly associated with the motor because it often requires precise leveling to achieve optimal performance and reduce stress on the entire system.
