ABSTRACT:
A tool to remove a retaining ring at least partially received in a groove of a cylinder has a handle lever constructed to engage the open end of the cylinder and a claw lever having a hooked end or claw constructed to be received at least partially underneath the retaining ring with the claw lever pivotally connected to the handle lever permitting relative movement between the two levers. The pivotal connection between the handle lever and claw lever permits them to be separated and joined together in a scissor-like fashion to facilitate engaging the claw with the retaining ring. When engaged with the retaining ring, the tool is pivoted about the cylinder to displace the claw and thereby displace the retaining ring inwardly and upwardly of the groove to remove it from the cylinder. The tool permits easy and non-destructive removal of the retaining ring and requires relatively low force and a relatively low level of skill to safely remove the retaining ring from the cylinder.
