Abstract
A method of hot drop fastening components and a product thereby made is described. Machine components are provided. A first machine component defines a passageway and carries a coating. The first machine component is caused to expand by delivering a predetermined amount of energy to the first machine component, wherein the predetermined amount of energy is based on a property of the coating. A second machine component is inserted into the passageway of the expanded first machine component. Thereafter, the first machine component is permitted to cool with the first machine component inserted in the passageway thereby fastening the first machine component with the second machine component by the first machine component contracting as it cools. Properties such as adhesion and/or rust prevention properties of a primer coating in a motor manufactured using a hot drop process are preserved during the hot drop process in the manufactured product.
