A tappet roller is a component in the valve train of an engine that helps to reduce friction between the camshaft and the valve stem. It is typically cylindrical in shape and made from hardened steel. The tappet roller rotates on its axis as it moves along the camshaft, allowing for smooth operation of the valves. The part number for this specific tappet roller is 154571. It is important to ensure proper lubrication of tappet rollers to prevent premature wear and damage to other engine components.
