A clutch structure has a housing in which is slidably disposed a fluid-operated piston, a plurality of inner and outer splined friction plates and a return spring assembly. The friction plates have formed thereon a spline portion such that alternating discs have the splines extending radially outward, engaging the housing, or extending radially inward, away from the housing. The clutch structure is assembled by positioning the clutch housing in a fixture composed of a ring which is sized to accommodate the outer spline of the one set of friction plates. The plates are arranged in two vertical stacks with the inner splined plates in one stack and the outer splined plates in the other. The plates are alternately installed in the housing by descending from the stacks solely by the force of gravity until a desired number of plates have been installed. The piston and a pressure plate can be installed in the housing prior to mounting the housing to the fixture, if desired. The return spring assembly and a backing plate are installed in the housing after the clutch plates have been installed.
