A roller tappet includes a body defining an elongated recess opening through the lower end thereof. A roller is rotatably mounted within the recess. The recess is dimensioned to substantially encircle and enclose said roller. The tappet body is cast from a variety of materials.

Roller tappet and method of making same

A roller tappet includes a central valve lifter body having a bifurcated end. A roller is supported at the bifurcated end and adapted for engagement by the lobes of a cam shaft. The valve lifter body reciprocates within a cylindrical bore defined by a cast iron engine block. The roller tappet body is formed from a ductile iron material thereby decreasing side wall wear and substantially eliminating galling between the valve lifter body and the wall of the cast iron tappet bore.
