ABSTRACT:
One end of the hollow valve lifter body is bifurcated forming two spaced supports. A roller is rotatably supported between the supports by a shaft and the circumferential edge rotates in a recess in the body end formed by plunge milling the wall portions of the body intermediate the support and providing a counterbore at the bifurcated end. Preferably, the counterbore is formed simultaneously with the fabrication of the body.
