Clutch housing and methods for preventing damage to clutch housings from clutch plates

A method for modifying a clutch housing to preventing damage thereto, the method comprising:

• removing a first clutch plate from the clutch housing, the first clutch plate having splines configured to be positioned between sides of castellations of the clutch housing, wherein the castellations extend upwardly in an axial direction;
• positioning wear inserts adjacent to the castellations, wherein each of the castellations comprises an inner face that extends between the sides therebetween, the inner face facing radially inwardly, wherein the wear inserts each comprise sides that extend perpendicularly from a base, wherein the wear inserts are positioned such that the sides thereof are adjacent to the sides of the castellations and such that the base of the wear inserts spans across the inner faces of the castellations, and wherein the wear inserts comprise tabs that extend in the axial direction farther than the bases when positioned with the castellations, whereby the tabs prevent the wear inserts from moving radially inwardly from the castellations;
• and
• positioning a second clutch plate within the clutch housing such that splines of the second clutch plate are positioned between the sides of the wear plates, wherein an open space between the sides of the wear inserts is narrower than the splines of the first clutch plate, and wherein the splines of the second clutch plate are narrower than the splines of the first clutch plate so as to fit between the sides of the wear plates.
