Patent ID: 7100264

Claim:
A method of installing at least a pair of bushings in an opening that extends between a first side and a second side of a work member, the method comprising: inserting a first tubular section of a first bushing into the opening, the first tubular section of the first bushing having a first circumferentially seamless outer circumference, a first circumferentially seamless inner circumference and a first radial flange connected to one end of the first tubular section, the first circumferentially seamless inner circumference surrounds a first opening that extends through the first tubular section; inserting a second tubular section of a second bushing into the first opening of the first tubular section of the first bushing, the second tubular section of the second bushing having a circumferentially seamless second outer circumference, a second circumferentially seamless inner circumference and a second radial flange connected to one end of the second tubular section, the second circumferentially seamless inner circumference surrounds a second opening that extends through the second tubular section, the second outer circumference sized to be closely receivable by the first circumferentially seamless inner circumference of the first bushing, the second radial flange of the second tubular section positioned opposite the first radial flange of the first tubular section; and radially expanding the second tubular section of the second bushing by an amount sufficient to cause a radial expansion of both the first tubular section of the first bushing and the opening in the work member, the radial expansion of the second tubular section causing a tight interference fit between the second bushing, the first bushing, and the work member, respectively, the radial expansion further causing the first radial flange to be moved axially, relatively closer to the second radial flange, the tight interference fit sufficient to axially and radially restrain the first tubular section and the second tubular section with respect to the work member.
