Abstract:
A camshaft lash adjustment process for an internal combustion engine having at least one camshaft journaled within a plurality of bearings within a cylinder head for the purpose of driving direct acting valve tappets, with said camshaft being driven at one end by a drive mechanism, with said process comprising the steps of:substituting a tiltable camshaft retainer for a camshaft bearing cap which is proximate the driven end of the camshaft, by installing said tiltable camshaft retainer in the place of said bearing cap;removing all remaining camshaft bearing caps;substituting a camshaft tilt limiter for one of the others of said plurality of bearing caps by installing the tilt limiter in the place of one of said other bearing caps;rotating the camshaft about an axis which is perpendicular to the camshaft centerline such that the camshaft rotates within the tiltable retainer, while moving from its installed position to a maximum tilt position defined by the tilt limiter, in which position the valve tappets actuated by the camshaft are exposed;adjusting one or more valve tappets;removing the tiltable camshaft retainer and the camshaft tilt limiter; andreinstalling the camshaft bearing caps.
