Abstract : This patent discloses a balance weight mechanism which is attached to a tubular engine shaft for correcting unbalance in the engine. The tubular shaft includes a stiffener plate mounted therein transversely to the rotational axis of the shaft. The balance weight mechanism includes a balance weight arm and a fastener for releasably fastening an end of the arm to a generally central location on the stiffener plate where the axis of rotation of the shaft intersects the plate. Spline teeth on the balance weight arm face toward the stiffener plate and are aligned to intermesh with an arc of an annular spline ring on the plate for holding the arm in a desired angularly adjusted position extending outwardly radially from the axis of rotation of the shaft when the arm is fastened tightly against the plate.
