🔍 Key Concepts

• Study the ballhead and flyweight labels in the MO-0092 diagram and how they are connected to the governor drive shaft. • Think about how centrifugal governors work: the flyweights must both rotate and move radially to signal speed changes. • Trace the motion paths: one for rotation from the driveshaft, another for up‑and‑down / outward‑inward movement going to the levers.

💭 Think About

• Ask yourself: which part of the system makes the flyweights spin with the engine, and which parts only move because the flyweights shift position? • Look at where the ballhead is mounted. Does it appear fixed to a rotating shaft, or is it part of a linkage that only moves vertically? • For each choice, decide whether that function sounds like rotational drive or linkage / feedback and match that to what the ballhead actually does in the drawing.

✅ Before You Answer

• Verify which component is directly driven by the driveshaft and how that drive reaches the flyweights. • Confirm which component actually contacts the floating lever—is it the ballhead itself or another linkage like the speeder rod or compensation lever? • Check whether the speeder spring and speeder rod act on the flyweights directly, or if they only change the force balance on the rotating assembly.
