The valve spring compressor tool according to claim 4, wherein said aperture is oblong in the direction of said axis of symmetry.Ħ. The valve spring compressor tool according to claim 1, wherein said compressor plate has an axis of symmetry extending in the direction between said first end and said second end, and said aperture is formed along said axis of symmetry.ĥ. The valve spring compressor tool according to claim 1, wherein said push rod engaging means comprises a depression formed in a bottom side of said compressor plate for receiving the top of said push rod.Ĥ.
The valve spring compressor tool according to claim 1, whereby the rotational torque applied to said crank down nut in the opposite direction causes upward axial movement of said crank down nut by threaded engagement between said counterbore and the rocker arm stud such that the upward axial movement of said crank down nut causes said compressor plate to pivot on the push rod to allow decompression of the spring.ģ. Whereby the rotational torque applied to said crank down nut in one direction causes said crank down nut axially to descend the rocker arm stud by threaded engagement between said counterbore and the rocker arm stud such that the downward axial movement of said crank down nut causes said compressor plate to pivot on the push rod and compress the spring.Ģ. Torquing means for applying rotational torque to said crank down nut and
A valve spring compressor tool 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 rocker arm stud and the valve spring, the tool comprising:Ī compressor plate having a first end with push rod engaging means and a second end with a spring engaging portion, and an aperture intermediate said first and second ends for receiving the rocker arm stud Ī crank down nut having a socket portion and a coaxial, reduced diameter neck portion, said socket portion having torque receiving means for receiving rotational torque applied to said crank down nut, and said neck portion having an internally threaded cylindrical counterbore axially extending into said neck portion to receive the rocker arm stud Ĭonnecting means for connecting said crank down nut to said compressor plate 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.ġ. 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. 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. passes through an oblong aperture in a compressor plate, where it is removably locked in position. 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.
