Abstract
In a method of minimizing the play in a valve operating mechanism having first and second valve operating rocker arms mounted side-by-side on a support shaft wherein each rocker arm has one end disposed on a cam of a cam shaft to be actuated thereby and, the first rocker arm has its opposite end disposed on a gas-change valve for operating the valve while the second rocker arm has at its opposite end a coupling bore disposed adjacent a coupling bore formed in the first rocker arm and a coupling pin is arranged in the coupling bore of one of the rocker arms and projects into the bore of the other for engagement of the rocker arms with one another, the two rocker arms are mounted in a coupled state on the shaft of a measuring arrangement, a force is then applied to the valve engaging end of the first rocker arm for firmly biasing the first rocker arm against a base circle location of its associated cam and a force is applied to the one end of the second rocker arm to force it away from its associated cam into firm engagement with the first rocker arm via the coupling pin and a support roller with a diameter essentially twice the distance between a support roller axis on the second rocker arm and the associated cam base circle surface is then selected for installation in the second rocker arm.
