Abstract: A piston such as used in axial piston hydraulic translating units, comprising a hollowed-out skirt portion defining a cavity filled with a core of lightweight filler material, the material being retained in place against axial displacement by convex disc core-retaining means forceably insertable within said cavity. In position, the core-retaining means further protects the core filler material from erosion due to high ambient fluid pressure.

Abstract: A ripper tip is removably attached to an end of a shank and has a point formed on each end thereof to facilitate reversal after one point has worn. Two pairs of apertures may be formed in a saddle mount portion of the ripper tip to align with respective bores formed in the shank to provide four adjusted positions therebetween.
