Product Description
The 639195 is a steel counterweight assembly for piston aircraft engine crankshafts. This component reduces torsional vibration and maintains rotating balance through pendulum-type dampening action within the crankshaft system. The counterweight absorbs harmonic oscillations, enabling smoother engine operation and reducing stress on drivetrain components.
Installation must follow the applicable engine overhaul manual and FAA-approved procedures, with compatibility verification in the engine Illustrated Parts Catalog. Used in general aviation and light aircraft piston engines requiring crankshaft balancing.
