Abstract

A cleaner finger assembly for cleaning compactor teeth on a compactor wheel of a compactor machine includes a cleaner finger base having a tip engaging surface and a base longitudinal axis, a cleaner finger tip having a base engaging surface and a tip longitudinal axis, and a finger tip anchoring mechanism attaching the cleaner finger tip to the cleaner finger base with the base engaging surface facing and engaging the tip engaging surface. The finger tip anchoring mechanism fails and the cleaner finger tip detaches when the cleaner finger tip is engaged by debris with a force parallel to the tip longitudinal axis, or with a force perpendicular to the tip longitudinal axis, to cause a tip shear force greater than a tip anchor shear capacity of the finger tip anchoring mechanism or a tension force greater than a tip anchor tension capacity of the finger tip anchoring mechanism.
