Review MOTO GUZZI Rare Tool Big Block Clutch Transmission Lot Le Mans fits TWINS
Rebuild Hardware Lot: Premium SKF 6206-2RST bearing German-made, spins freely, note: surface rust/small puncture in one rubber shield, high-tension clutch springs, and four vintage shaft seals including Cortege. Up for sale is a solid vintage lot of mechanical components and spares classic Big Block Moto Guzzi Motorcycle project. This is a comprehensive job lot containing: OEM Dry Clutch Components: AP marked/M12F57 stamped clutch plates and pressure backing plate. Shipping: Ships fast.
Transmission Internals: Input hub/center boss, 3 constant-mesh gears, selector dog, and starter ring gear. They have been lightly wiped down but are being sold as-found, as-is perfect for a classic builder who knows how to clean up and utilize high-quality vintage Italian iron. This kit directly fits a huge lineage of famous classic 750cc, 850cc, and 1000cc Italian machines. Clean teeth, solid splines.
Transmission Constant-Mesh Gears: Three individual internal gearbox gears with clean teeth and intact splines. As with any imperfect human, I could be wrong some of the specifics. Clutch Pressure Plate Hub: Steel backing pressure plate alongside the heavy, stepped splinted clutch hub/boss. Clutch Springs: A set of heavy-duty, high-tension clutch compression springs.
They show authentic wear, grease, and expected surface rust/patina from storage, but they are structurally intact with solid teeth splines. Gear Selector Dog: One castellated engagement dog sleeve ring. Calling all classic Moto Guzzi restorers. Probably not likely Lola but SERIOUSLY Please study the photos closely to verify fitment for your specific classic Moto Guzzi model year and engine size before purchasing.
Condition: These are used, vintage mechanical parts. Flywheel Starter Ring Gear: Heavy outer ring gear with fine teeth meant for electric starter engagement.
