ABSTRACT:
A valve spring compression tool is provided and consists of a C-shaped frame having at a first extremity a fixed pad with a central aperture therethrough. A structure at a second extremity of the C-shaped frame is for moving a movable pad toward and away from the fixed pad in an axial alignment. When a valve head of a valve bears against the fixed pad a valve spring can be compressed to release a pair of retaining members from a valve stem through the central aperture so that the valve can then be disassembled.
