A load wheel assembly for a materials handling vehicle includes first and second spaced side members, at least one rotatable roller extending between the first and second side members. An interface structure provides a substantially rigid connection between the load wheel assembly and a mounting structure on the materials handling vehicle. The mounting structure includes a transverse bar and the interface structure includes a portion that engages and mates with the transverse bar to form a rigid connection between the interface structure and the transverse bar.

1. A method of installing a load wheel assembly on an outrigger for a materials handling vehicle, the outrigger comprising an outrigger box comprising a pair of laterally spaced bearing plates defining a load wheel opening for receiving a load wheel assembly, and a transverse bar extending laterally across said load wheel opening, and said load wheel assembly comprising at least one roller supported on an axle between a pair of side support members and an interface structure extending between said pair of side support members, the method comprising: positioning said load wheel assembly in said load wheel opening with said interface structure located above said transverse bar;engaging at least one threaded fastener between said interface structure and said transverse bar; androtating said fastener to draw said transverse bar toward engagement with said interface structure. 2. The method of claim 1, wherein said rotating said fastener effects a vertical movement of said outrigger from a support surface wherein said at least one roller supports said outrigger in spaced relation to said support surface during said vertical movement of said outrigger. 3. The method of claim 2, wherein two fasteners are located in laterally spaced relation to each other and engaged between said interface structure and said transverse bar, and said rotating said fastener comprises alternately rotating each of said fasteners to move said transverse bar a portion of the distance toward said interface structure. 4. The method of claim 1, including providing an assembly retention tool having side member engagement structure and, prior to positioning said load wheel assembly in said load wheel opening, locating said side member engagement structure of said assembly retention tool adjacent at least a portion of said side support members to retain said side support members in engagement with said axle and said interface structure to define a load wheel preassembly. 5. The method of claim 4, including positioning a lower portion of said load wheel preassembly in said load wheel opening and displacing said side support members downwardly into said load wheel opening and away from said side plates of said assembly retention tool. 6. The method of claim 5, wherein said positioning said lower portion of said load wheel preassembly in said load wheel opening includes lowering said load wheel preassembly into recessed areas formed in said bearing plates. 7. The method of claim 4, wherein said side support members each comprise an aperture for receiving a respective end of said axle, each said aperture receiving said respective ends of said axle in sliding engagement, and said side support members being positioned in engagement with an inner surface of one of said bearing plates for retaining said side support members in engagement with said ends of said axle. 8. The outrigger assembly of claim 7, wherein said inner surfaces of said bearing plates comprise recessed areas for receiving said side support members therein. 9. The method of claim 4, wherein said side member engagement structure comprises a pair of laterally spaced side plates supported on a base plate. 10. The method of claim 9, wherein said interface structure includes a threaded aperture and said assembly retention tool includes a threaded shank and a nut located adjacent to said base plate and engaged on said threaded shank, said locating said side member engagement structure adjacent said side support members to define a load wheel preassembly comprising: threading said threaded shank into said threaded aperture of said interface structure; androtating said nut on said threaded shank to draw said interface structure toward said base plate. 11. The method of claim 10, wherein, prior to said positioning said load wheel assembly in said load wheel opening, removing an initial load wheel assembly from said load wheel opening including rotating a fastener located in engagement with said initial load wheel assembly to effect lowering movement of said outrigger to engagement with said support surface. 12. The method of claim 11, further including: placing said assembly retention tool over said initial load wheel assembly;threading said threaded shank into said threaded aperture of said interface structure of said initial load wheel assembly; androtating said nut on said threaded shank to draw said interface structure from said load wheel opening. 13. A method of installing a load wheel assembly on an outrigger for a materials handling vehicle, the outrigger comprising an outrigger box comprising a pair of laterally spaced bearing plates defining a load wheel opening for receiving a load wheel assembly, and a transverse bar extending laterally across said load wheel opening, and said load wheel assembly comprising at least one roller supported on an axle between a pair of side support members and an interface structure extending between said pair of side support members, the method comprising: providing an assembly retention tool having side member engagement structure;locating said side support members adjacent to said side member engagement structure to define a load wheel preassembly;positioning said preassembly over said load wheel opening; andlowering said load wheel assembly from said retention tool into said load wheel opening. 14. The method of claim 13, wherein said positioning said load wheel assembly in said load wheel opening includes positioning said interface structure above said transverse bar, and further including: engaging at least one threaded fastener between said interface structure and said transverse bar; androtating said fastener to draw said transverse bar toward engagement with said interface structure. 15. The method of claim 13, wherein said side member engagement structure comprises a pair of laterally spaced side plates supported on a base plate, and said load wheel preassembly includes said side support members located in engagement with inner surfaces of said laterally spaced side plates. 16. The method of claim 15, wherein said laterally spaced side plates include respective recessed areas for receiving upper portions of said side support members, said positioning said preassembly over said load wheel opening includes locating said assembly retention tool on said outrigger box with upper portions of said side support members received within said recessed areas. 17. The method of claim 15, wherein said interface structure includes a threaded aperture and said assembly retention tool includes a threaded shank and a nut located adjacent to said base plate and engaged on said threaded shank, said locating said side member engagement structure adjacent said side support members to define a load wheel preassembly comprising: threading said threaded shank into said threaded aperture of said interface structure; androtating said nut on said threaded shank to draw said interface structure toward said base plate.
