In single-speed electric start engines, removing the clutch is not a difficult activity, especially if you follow Dr. TKART’s guide “Checking and replacing the single-speed engine clutch“. However, it is necessary to have a specific extractor, a tool to be anchored to the clutch and which, by means of a pin that needs to be screwed in, pushes against the crankshaft to extract the clutch from its conical housing. Before purchasing an extractor, it is necessary to check the internal diameter of the clutch, in other words the seat where the extractor cone is screwed into, which varies in diameter depending on the type of engine.
