A landing gear assembly configured to support a trailer, comprising:
- a leg assembly including a first leg member and a second leg member telescopingly received within the first leg member and adjustable between a retracted position and an extended position;
- a gear assembly operably coupled to the leg assembly and configured to move the first leg member between the retracted and extended positions, wherein the gear assembly includes a first shaft member and a first gear where the first shaft member and the first gear are a single, integral piece;
- a first bushing member including a bushing portion having a bushing portion and a closed end and rotatably supporting a first end of the first shaft member within the first leg member;
- and
- a second bushing member including a bushing portion having a bushing portion and a closed end and rotatably supporting a second end of the first shaft member within the first leg member.
A method of assembling a landing gear assembly configured to support a trailer, comprising:
- providing a leg assembly including a first leg member and a second leg member telescopingly received within the first leg member and adjustable between a retracted position and an extended position, the first leg member having an open end, a first aperture extending through a first sidewall and a second aperture extending through a second sidewall;
- providing a gear assembly that includes a first shaft member and a first gear where the first shaft member and the first gear are a single, integral piece, wherein the gear assembly is configured to move the second leg member between the retracted and extended positions;
- positioning the first shaft member and first gear within the first leg member by passing the first shaft member and first gear through the open end of the first leg member, extending a first end of the first shaft member through the first aperture and extending a second end of the first shaft member through the second aperture;
- providing a bushing member that includes a bushing portion having a closed end and a plate portion extending outwardly from the bushing portion;
- attaching the first bushing member to the first wall of the first leg member such that the first bushing member rotatably supports the first end of the first shaft member;
- providing a second bushing member that includes a bushing portion having a closed end and a plate portion extending outwardly from the bushing portion;
- and
- attaching the second bushing member to the second wall of the first leg member such that the second bushing member rotatably supports the second end of the first shaft member.
