Beschreibung
Zusammenfassung:	A roller valve lifter, especially of the hydraulic lash adjusting type for diesel engines, has an enlarged bronze roller shaft journal for extended wear with a diameter at least half that of the surrounding skirt of the lifter body within which it is mounted. The roller/shaft assembly is received in a recess through the open bottom end of the lifter body, the shaft having mounting tangs with flats which engage abutments in the recess to locate the roller in the recess. Retention is preferably by staking portions of the tangs into recesses in the skirt, preferably formed by openings adjacent the ends of the tangs.
