<p>A maintenance-free pivot joint (10) is disclosed for mounting a first member (16) of a loader linkage (12) to a second member (18) thereof. The first member (16) is provided with a clevis (62) having a pair of brackets (64, 66). The pivot joint (10) includes a pivot pin (60) which is pivotally mounted within the second loader linkage member (16). A first end collar (64) is fixedly secured to one end of the pivot pin (60) of the joint (10) and is slidably mounted to a first one of the pair of brackets (64). Conversely, a second end collar (74) is slidably mounted on the other end of the pin (60) and fixedly secured to a second of the brackets (66), but at a preselectable axial position relative to the second member (16). The positioning of the second end collar (74) at the preselected position allows the joint (10) to accommodate lateral misalignment between the first and second members (16, 18) of the linkage (12), while maintaining a closely spaced lateral relationship therebetween to eliminate end play and facilitate good sealability.</p> |
