JimsThis patent pending "on bike" valve spring compressor kit for Milwaukee-Eight engines works with the cylinder head installed on the motor. Simply remove the rocker box cover and rocker arms and install this unique compressor on the rocker arm shaft. Once the cylinder is filled with compressed air the technician can easily rotate the tool and compress the top collar of the valve spring exposing the keepers to remove the top collar, valve spring, and seal.
