In which context would shims not be used during assembly?

Shims are typically used in various contexts during assembly, particularly for adjusting alignment, correcting backlash, and making height adjustments. Their primary role is to fine-tune the fit and function of components, ensuring that everything operates smoothly and efficiently.

In the scenario of balancing weight distribution, shims are not generally employed. Weight distribution is primarily managed through design considerations and the structural placement of components rather than the addition of shims. While shimming can influence how weight is distributed in specific applications, it does not serve as a standard method for achieving balance. Instead, manufacturers often focus on the arrangement and design of parts during the initial engineering phase to ensure optimal weight distribution without relying on shims to compensate for uneven weight.
