ABSTRACT:
Rocker arm clearance removing device wherein a hydraulic adjuster applies torque to a pressure bearing surface at right angles thereto on a curved outwardly extending pressure bearing arm of an eccentric cam which eccentrically supports the rocker arm. Rotation of the rocker arm resulting from the torque causes the rocker arm to come into pressure contact with a valve operating cam and an intake or exhaust valve. An engaging piece can be provided radially extending from the eccentric cam circumferentially spaced from the pressure bearing arm for engaging a swivel stop on the case of the hydraulic adjuster to limit swinging of the eccentric cam and rocker arm during assembly. An arm stopper can also be provided on the case of the hydraulic adjuster to prevent swinging of cam and rocker arm in the opposite direction during assembly.
