ABSTRACT:
An improved lash adjuster assembly (100) of the type featuring a plunger member (20) reciprocally moveable within a bore (44) of a body member (2) and operable to reduce back lash in a drive train of an engine valve member wherein assembly (100) includes a retainer member (66) having a side wall (74) secured to body member (92) and having radially inwardly projecting section (76) having at least a portion thereof dimensionally adapted and of sufficient resilience to minimize impact between a shoulder (68) of plunger member (20) as well as enabling plunger member (20) to be removed from body member (2) without having to remove retainer member (66) from securement thereto in addition to enabling greater reciprocal travel of plunger member (20) relative body member (2) during operation of assembly (100) particularly due to softening of at least section (76) of retainer member (66) at elevated engine temperatures.
