It ships with the mounting bolt, washer kit and a tightening wrench so you have the hardware needed for straightforward installation on compatible crankshafts. The clutch is built to engage around typical small‑engine speeds and is commonly used on Predator 212 clones, Honda small engines (GC\/GX series), and other 2–6.5 HP motors that share a 3\/4\" shaft and 3\/16\" keyway.\n\n\u003ch3\u003eWill this clutch fit my engine and chain?\u003c\/h3\u003e\n\u003cp\u003eCheck the crankshaft diameter and keyway before ordering: the Beitetoo clutch requires a 3\/4\" (19.05 mm) shaft and a 3\/16\" keyway. It is designed for #40\/#41\/420 chain, whose 0.5\" pitch matches the 10T sprocket profile. Many 2–6.5 HP Honda, clone and Tecumseh engines, plus popular 5.5–6.5 HP clone motors, are compatible if they share these dimensions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFits engines with 3\/4\" shaft and 3\/16\" keyway\u003c\/li\u003e\n  \u003cli\u003eWorks with #40, #41, and 420 chain (0.5\" pitch)\u003c\/li\u003e\n  \u003cli\u003eCommonly compatible with Honda GC\/GX and many clone engines\u003c\/li\u003e\n  \u003cli\u003eNot suitable for 20 mm (0.787\") generator shafts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow difficult is installation and initial setup?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward: mount the clutch onto the crankshaft, insert the key, then secure with the supplied bolt and washers.
