Chevrolet Corvette Rocker Arm
The Rocker Arm in Chevrolet Corvette automobiles is a crucial component of the valvetrain system It rotates the motion of the pushrod to the valves of both, intake and of the exhaust. Customarily made of stamped steel or aluminum, the Rocker Arm translates the oscillatory movement of the pushrod vertically into the required amount of force needed to lift the valves. In high RPM applications, aluminum is incorporated owing to its lightweight, while CI or forged carbon steel is implemented in other applications. Chevrolet Corvette models have adopted different Rocker Arm designs: conventional and roller types. Overhead valve as well as overhead camshaft engines benefit with roller rockers that include needle bearings for decreasing friction. The rocker ratio known to vary between 1.5 to 1.8 in modern engines escalates the camshaft lift to improve on performance. Sintered fulcrum bearings are also used in the version of the fast-rotating Corvettes to increase its durability and performance when subjected to greater loads.
Each OEM Chevrolet Corvette Rocker Arm we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
Chevrolet Corvette Rocker Arm Parts Questions & Experts Answers
- Q: How do you remove and reinstall the Pushrod and Rocker Arm on Chevrolet Corvette?A: To remove the valve covers from the Cylinder Heads, first loosen the rocker arm pivot bolts one at a time and take out the rocker arms and bolts, followed by the pivot support pedestal if equipped, ensuring to keep track of the rocker arm positions for reinstallation. Store each set of rocker components in marked plastic bags to maintain their original locations, noting that the 7.0L (LS7) engine does not use pivot support pedestals and that the intake rocker arms are offset while the exhaust rocker arms are not. Next, remove the pushrods and store them separately to avoid mixing them up, paying attention to the arrow indicating the front of the engine. Inspect each rocker arm for wear, cracks, and damage, particularly at the contact points with the pushrods and valve stems, and check the pivot bearings for binding or roughness, as worn bearings will necessitate replacing the entire rocker arm. Additionally, examine the rocker arm pivot support pedestal for cracks and ensure the hole at the pushrod end of each rocker arm is clear. Inspect the pushrods for cracks and excessive wear, ensuring the oil hole is not clogged, and roll each pushrod across a flat surface to check for bending. For installation, lubricate the lower end of each pushrod with clean engine oil or assembly lube and reinstall them in their original locations, ensuring they seat completely in the lifter socket. Apply engine assembly lube to the ends of the valve stems and upper ends of the pushrods to protect mating surfaces during initial start-up, then apply clean engine oil to the pivot shaft and bearing of each rocker arm before loosely installing them in their original locations without tightening the bolts. Rotate the crankshaft until the number one piston is at TDC, then tighten the intake valve rocker arms for cylinders 1, 3, 4, and 5, and the exhaust rocker arms for cylinders 1, 2, 7, and 8, ensuring each rocker arm bolt is tightened to the specified torque. Rotate the crankshaft 360 degrees and tighten the intake valve rocker arms for cylinders 2, 6, 7, and 8, and the exhaust rocker arms for cylinders 3, 4, 5, and 6, again ensuring proper torque. Finally, install the valve covers, start the engine, and listen for any unusual valve train noises while checking for oil leaks at the valve cover gaskets.
