ABSTRACT:
Apparatus for removing a valve adjusting disc from a valve lifter in a valve mechanism of an engine cylinder head includes an elongated rigid cross-bar supported on the engine cylinder head and extending generally parallel to the camshaft above the valve lifters. A force-applying member slides on the cross-bar and is straddled by an adjustment screw retainer that also slides on the cross-bar. The force-applying member has a downwardly extending arm with a lower working face that contacts the valve lifter independently of contact with the valve adjustment disc. An adjustment screw carried on the retainer is turned to apply downward force on the force-applying member, which forces the arm downwardly against the resistance of the cross-bar for compressing the valve lifter against the bias of the valve spring. This moves the valve lifter downwardly away from the valve adjustment disc, while the valve lifter is retained in its compressed position, so the valve clearance can be measured and the valve adjustment disc can be removed from the valve lifter, if desired.
