When changing valve springs for performance upgrades, or simply replacing a leaking valve seal, it is necessary for the technician to completely remove the cylinder head from the engine. This adds unnecessary time and expense. JIMS has developed a creative new tool that eliminates this step completely. This patent pending in.on bikein. valve spring compressor kit for Milwaukee Eight engines, works with the cylinder head installed on the motor. Simply remove the rocker box covers 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. This patent pending tool dramatically saves time for any technician working on Milwaukee Eight performance upgrades or service work.
Works great with Jims Leakdown Tester # JM-782!
