ABSTRACT:
A yoke-type pivot joint includes a first member having a pair of parallel portions provided with holes which are axially aligned with each other and with a hole provided in a second member located between the parallel portions. A bushing is press fit into the hole in the second member and a pin is received in the bushing and in the holes in the parallel portions. First and second pairs of opposed Belleville spring seals are respectively located between the pair of parallel portions and the opposite end of the bushing. The parallel portions contain respective slots extending from the holes therein and fasteners are provided to clamp the slots together to thus clamp the parallel portions on the pin at selected locations for positioning the parallel portions for effecting compression of the Belleville springs.
