Abstract: A method is disclosed for constructing and adjusting a plurality of release levers of a friction disc clutch. The method ensures that the inner or nose ends of the release levers lie in a common plane upon final clutch assembly. In a preferred embodiment, a rivet is secured to the nose end of each release lever. The resulting lever unit is heat treated in a manner wherein the attached rivet is hardened throughout its entirety, while the lever per se is case hardened to a specified depth.Next, a clutch cover, pressure plate, pressure means for urging the plate, and the plurality of heat treated lever units are installed together to form a clutch cover sub-assembly. Relative movement between the clutch cover and pressure plate is effected against the bias of the pressure means until the levers are in an extreme position relative to the clutch cover.
