ABSTRACT:
A method of manufacturing an end assembly of an engine oil cooler with an apparatus that includes (i) a compression member having a roller surface defined thereon, (ii) a motor operatively coupled to the compression member such that the motor can rotate the compression member around a central axis of rotation, and (iii) a drive cam for urging the compression member outwardly from the central axis of rotation, wherein the end assembly includes (i) an outer component which defines a first lumen and (ii) an inner component which defines a second lumen is described. The method includes the steps of (i) creating a channel in an interior surface of the outer component, (ii) positioning the inner component within the first lumen, (iii) locating the compression member within the first lumen and the second lumen such that (A) the compression member is completely contained within the first lumen and the second lumen and (B) the roller surface is in contact with the inner component and aligned with the channel, (iv) rotating the compression member around the central axis of rotation with the motor, and (v) moving the drive cam so as to cause the roller surface of the compression member to be urged against the inner component thereby causing a portion of the inner component to deform and move into the channel of the outer component thereby securing the inner component to the outer component.
