ABSTRACT:
A maintenance-free pivot joint is disclosed for mounting a first member of a loader linkage to a second member thereof. The first member is provided with a clevis having a pair of brackets. The pivot joint includes a pivot pin which is pivotally mounted within the second loader linkage member. A first end collar is fixedly secured to one end of the pivot pin of the joint and is slidably mounted to a first one of the pair of brackets. Conversely, a second end collar is slidably mounted on the other end of the pin and fixedly secured to a second of the brackets, but at a preselectable axial position relative to the second member. The positioning of the second end collar at the preselected position allows the joint to accommodate lateral misalignment between the first and second members of the linkage, while maintaining a closely spaced lateral relationship therebetween to eliminate end play and facilitate good sealability.
