ABSTRACT:
A reservoir height extender for a lash adjuster assembly (150) comprising an inverted hollow insert member (60) disposed in fluid reservoir chamber (42) within a plunger member (40) of assembly (150). Plunger member (40) is reciprocally moveable within a bore (38) of a body member (36) having a first fluid passageway (48) adapted to receive fluid from a fluid source and which communicates with a second fluid passageway (46) in plunger member (40) adapted to enable the fluid to flow into fluid reservoir chamber (42). Insert member (60) is displaced from a wall of plunger member (40) surrounding chamber (42) for a distance sufficient to provide a third fluid passageway (68) therebetween which communicates between passageway (46) and an opening (64) through insert member (60) that is higher than passageway (46) and which enables a substantial increase in the level of fluid within reservoir chamber (42).
