It is recommended that the engine be removed from the vehicle for camshaft removal. Remove rocker arms and pushrods, engine front cover, fuel
pump and distributor, and the side cover and lifters, noting position of components for installation. Remove camshaft thrust plate screws and pull
camshaft from cylinder block. During installation, coat cam lobes and lifters with suitable break-in lubricant. If the camshaft is replaced, it is
recommended that the lifters be replaced also. If components are reused, they should be installed in original positions.
