ABSTRACT:
A tool assembly for installing and removing horizontally oriented retaining pins in a mechanical joint between a bucket tooth and a tooth adapter includes first and second lever members and first and second threaded members which are threadably connected to the respective first and second lever members. The second lever member is pivotably connected to the first member. The tool assembly is adapted to be placed over a bucket tooth having a horizontally oriented retaining pin, with the second threaded member aligning with and contacting the retaining pin. As the first threaded member is rotated, a portion of the first lever member contacts the tooth and the second threaded member contacts the pin and forces the pin into the joint, or out of the joint. Conventionally, a large drift pin and hammer are used to remove retaining pins. However, these tools are not useable on horizontally oriented retaining pins. The subject tool assembly quickly and easily installs and removes retaining pins in a joint between a bucket tooth and a tooth adapter.
