Abstract
A close tolerance pin connection includes a cylindrical connecting pin. A first sturcture has a first pin receiving hole disposed therethrough for closely receiving the connecting pin. A second structure has a second pin receiving hole disposed therethrough for loosely receiving the connecting pin. A weld washer has a third pin receiving hole disposed therethrough for closely receiving the connecting pin, and the weld washer is adapted to be located adjacent and engage the second structure. The connecing pin is received in the first, second and third pin receiving holes and the weld washer is then welded to the second structure so that the first and second structures are connected by the connecting pin. The connecting pin is closely received within the first hole of the first structure and is also closely received in the third hole of the weld washer which is fixed to the second structure, thus providing a close tolerance pin connection between the first and second structures after the weld washer is welded to the second structure.
