ABSTRACT:
A tool for removing valve springs and seals from an engine's intake and exhaust valves includes a bracket having apertures spaced therealong and for receiving fastening members therethrough. The tool further includes a plurality of support pedestals provided with channels extending therethrough and for receiving the fastening members respectively so that the bracket is maintained at a substantially stable position. The tool also includes a mechanism for simultaneously compressing a valve head keeper and releasing associated locks so that a user can remove the valve springs and valve seals from the valve head. The compressing mechanism cooperates with the pedestals and the bracket and is rotatable about a fulcrum axis traversing the pedestals wherein the fulcrum axis extends along a horizontal plane subjacent the bracket.
