Abstract: A sliding door roller system comprises a roller housing comprising a pair of generally vertical side members and an integral base portion including a projection on an inner surface thereof, the roller housing at least partially disposed within an outer housing; at least one roller wheel rotatably coupled to the roller housing; an outer housing moveable relative to the roller housing and the at least one roller wheel in a direction perpendicular to a rotational axis of the at least one roller wheel; and a rotatable adjustment mechanism coupled to the roller housing and the outer housing. The adjustment mechanism is rotatable from an exterior of the outer housing and is adapted to index the outer housing relative to the roller housing in a plurality of height positions in situ under load of a panel secured to the outer housing.

Abstract: THE INVENTION provides aligning means for aligning apertures in a motor vehicle wheel or wheel adapter, and a hub for securing purposes, comprising an oversize aperture in the wheel or adapter, s socket formation concentrically disposed relative the oversize aperture therein, and of a larger diameter than such aperture, and a disc or washer member located in the socket and rotatable therein about the axis of the socket, the disc member having an aperture therethrough which is eccentrically disposed relative to the axis thereof, so that the aperture in the disc member can be aligned with the adjacent aperture through rotational adjustment of the disc member, the oversize aperture having a large enough diameter to expose the eccentric aperture in selected or all angular positions of the disc member.
