ABSTRACT:
A valve spring compressor tool useful for removing valve springs from an overhead valve engine of the type having a threaded rocker arm stud adjacent the valve spring and a push rod aligned with the stud and the valve spring. The valve spring compressor tool of the present invention utilizes a crank down nut that has a socket portion for connection to a wrench and a neck portion which. passes through an oblong aperture in a compressor plate, where it is removably locked in position. The crank down nut has a threaded counterbore in its neck portion which threadably engages the rocker arm stud for descending and ascending the length of the stud as the crank down nut is rotated by a socket wrench connected to the socket portion. Axial movement of the crank down nut causes the compressor plate to pivot about its connection with the push rod for compression of the valve spring. A bifurcated end of the compressor plate contacts a retainer cap on the valve spring to compress the spring without interfering with the valve stem or a keeper on the valve stem, which allows for removal of the keeper while the spring remains compressed.
