The clutch often is tight on the crankshaft taper. This extractor helps you to quickly detach the clutch without damaging anything.
Perfect to compress the clutch, thus unloading the safety ring. You may exchange the discs quickly and safely.
TECHNOLOGY-HINT: A securing nut tightens the 6 and 7 spring clutches of Vespa Largeframe models. High performance engines often don't reach the necessary high tightening torque with a securing nut.
Causing the woodruff key to shear off and the clutch hub to distort on the crankshaft. "Screwed" on the taper in this manner, you won't be able to loosen the entire clutch easily after loosening the securing nut of the crankshaft as you usually would. You should rather expect fierce resistance. This is where the extractor is particularly valuable.
TIP: We recommend our special nut with hex head for clutches with 6 or 7 springs. Easier and safer to use than ordinary securing nuts. It's made of extremely solid base material. The tightening torque can be fully used.
