Abstract: In one aspect, a vibratory tool is provided for driving a plurality of rivets out from bores of a guide block into an underlying conveyor belt. The tool has a body, a hydraulically operated main drive rod mounted to the body, and a driver aligned with the main drive rod and slidably mounted to the body. The driver has a plurality of elongated drive rod members for engaging and simultaneously driving multiple rivets out of the guide block bores. The driver has an intermediate impact surface for being impacted by the main drive rod impact end as the main drive rod impact end rapidly reciprocates between retracted and extended positions. The driver also has a rearwardly extending spacer wall for axially spacing the driver intermediate impact surface and the main drive rod impact end in the retracted position thereof by at least a predetermined axial distance sized for optimizing energy transfer from the main drive rod to the driver.
