Flywheel or ring gear holding tool for Big Twin Guzzi GU12911801

12911801 Similar to the factory tool (at less than 15% of it's cost!), this tool prevents the crankshaft from turning by holding both the flywheel, or the ring gear while you torque on fasteners on the crankshaft or camshaft. Simply flip it over depending on what stage of assembly you are in. Made in USA of heavy stainless steel. Suitable for use to secure the starter ring gear or the flywheel on any Big Twin 4, 5 or 6 speed transmission model, with a dual plate clutch. Will retain the starter ring gear only on other Big Twin models using only a single clutch plate system, such as the Scura, some V11 California series models, CARC models or automatics Convert and California II auto. Not suitable for use on California 1400 models or MGX21.
