ABSTRACT:
A valve spring compressor tool has a tubular member that screws at one end on to the rocker arm stud and has a body portion linked at the opposite end that slides down the tubular member. By pulling down on the handle of a bell crank type linkage, a position adjustable extending U-shaped finger element attached to the body portion engages the top of the adjacent valve spring and compresses the spring. An over-center feature of the linkage holds the spring in the compressed condition. The tubular member has different size threads at each end and can be inverted to fit each of the two standard size rocker arm stud threads.
