557-7254: Rocker Arm

Description: Cat® Engine Inlet Rocker Arm is a device that transfers the motion of the camshaft to the intake and exhaust valves in a engine inlet. It is a vital component that affects the engine performance, efficiency, and emissions. Cat manufactures high-quality rocker arms for various types of engines and applications. They are made of aluminum casting, which are durable, lightweight, and resistant to corrosion and wear. They have roller or needle bearings at the contact points, which reduce friction, noise, and heat generation. They have adjustable screws, which allow for precise and easy valve clearance adjustment. They have optimized geometry and balanced weight distribution, which improve the valve operation and timing. They have coatings or treatments, such as chrome plating, nitriding, or anodizing, which enhance the surface hardness and smoothness. Cat rocker arms are compatible with different models of camshafts, pushrods, valve springs, and lifters. Cat® Rocker arms are tested and certified to meet the highest standards of quality and reliability. Application: Cat® Rocker arms are used in inlet and exhaust valves of Cat® Engine.
