  • Camshaft lash adjustment process and system for internal combustion engine
    Patent number: 6024063
    Abstract: A camshaft lash adjustment process for an internal combustion engine includes the steps of substituting a tiltable camshaft retainer for a camshaft bearing cap which is proximate a driven end of the camshaft, followed by removal of all remaining camshaft bearing caps and the substitution of a camshaft tilt limiter for one of the camshaft bearing caps so as to allow rotation of the camshaft to a tilted position. This permits adjustment of valve tappets driven by the camshaft.
