1. A gearbox assembly comprising:

  • a pinion gear including a gear stem defining an axis, said gear stem having a threaded portion;

    an output member including an output flange and a tubular output stem, said output flange including an inner circumference coaxial with said tubular output stem, wherein said gear stem extends axially through said tubular output stem and said inner circumference such that said threaded portion protrudes from said output flange; and

    a pinion nut including a threaded inner bore and an outer rim, said threaded inner bore threadably engaging said threaded portion of said gear stem thereby retaining said output member to said pinion gear, said outer rim defining an outer circumference including at least one tool recess and at least one deformation spaced circumferentially apart from said at least one tool recess, wherein said at least one tool recess is adapted for receiving a tool to rotate said pinion nut in a first direction relative to said gear stem, and said at least one deformation engaging said inner circumference of said output flange thereby preventing said pinion nut from rotating in a second direction relative to said gear stem.
