ABSTRACT:
An oil filter crusher includes an elongated triangular frame, a threaded drive screw, and a ram assembly, but does not include any actuator for driving the screw. Rather, a first end of the drive screw has a drive head to which a user may couple a conventional wrench, such as a pneumatic impact wrench of the type commonly used in automotive service centers. A thrust bearing assembly couples the second end of the drive screw to the ram assembly. A threaded portion of the drive screw engages a threaded opening in a portion of the frame. The ram assembly thus moves in an axial direction in response to rotation of the drive screw with respect to the frame. Rotating the drive screw in one direction moves it toward the filter to be crushed, and rotating it in the opposite direction moves it away from the filter.
