Analysis of Specifications
Twin Belt: Indicates a dual pulley clutch designed to accommodate two V-belts (likely A or B size, e.g., 1/2" or 5/8" width).
Complete Standard: Suggests a standard configuration, possibly a common bore size (e.g., 3/4" or 1") and pulley setup for typical engines like Honda GX series or equivalents.
Shaft Short: Implies a shorter-than-standard crankshaft length, though "short" is not universally defined. In clutch contexts, this might mean a spline length of ~22mm or less, or a specific bore size (e.g., 3/4" or 20mm).
Dimensions (3.5" x 4.8" x 3.3"): Likely refers to the clutch’s overall size (e.g., width x length x height or pulley diameter x height x width). The 4.8" could indicate pulley diameter, and 3.3" could be height, but this needs confirmation.
Weight (4 kg / 8.8 lbs): Lighter than many heavy-duty dual pulley clutches (e.g., Revolution Clutches’ models weigh 14.5 lbs), suggesting a compact or lighter-duty unit.
