ABSTRACT:
The disclosure illustrates a valve spring compressor tool which may be used to remove heavy duty double valve springs from an engine with no more disassembly of the engine than removal of the rocker cover. The tool comprises a support bridge bolted to the rocker housing across the valves to be compressed. A plate having two cup-like recesses fits over the valve springs and a central sleeve passes through the plate to guide it for movement parallel to the normal direction of compression for the springs. A shaft is threaded into the cross arm and is aligned with the sleeve so that rotation causes it to exert a compressive force of great magnitude and retains the valve in the compressed position.
