GMC Yukon Rocker Arm

The Rocker Arm used in GMC Yukon automobiles is very significant in the engines valvetrain system as it helps convey movement from the pushrod to the intake and exhaust valves. Usually made from stamped steel or aluminum, these parts translate the up-down articulation of the pushrod into the downward force required to open the valves. In the applications with high rotational speed such as in automotive engines, aluminum is favored for weight considerations whereas cast iron or forged carbon-steel is employed in the diesel engines for power-providing construction. Different types of rocker arms including the roller rockers use needle bearings in a bid to eliminate friction and hence enhance durability. The rocker ratio which is standardly a minimum 1.5:1 to a maximum of 1.8:1 in the contemporary motors heightens cams lift subsequently enhancing performance. Previously, such ratios as 1:1 were typical up to the 1950s. The new fulcrum bearings are also used where the pressure is likely to build up, particularly in high revving engines, to provide additional strength and thus boost the efficiency of the rocker arm.

Each OEM GMC Yukon 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.

    Q: How to remove the Pushrod and Rocker Arm on V8 engine for Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
    A: Removing of valve covers from the Cylinder Heads is to be done by first of all removing one at a time each Rocker Arm Pivot Bolt and taking out the rocker arms, bolts and pivot support pedestal. Keep track of their positions and store them separately. Proceed by removing the pushrods, keeping them in sequence as they are. Each rocker arm has to be checked for wear, cracks, damage as well as binding and roughness of the pivot bearings during inspection. The rocker arm has to be replaced if its bearings are worn or damaged. Also examine the rocker arm pivot support pedestal for any cracks. Make sure that all the pushrods are open at the hole on each of their rocker arms' ends and check them for fractures, large amounts of wear or obstruction in oil holes. After lubricating them with clean engine oil or assembly lube, put back the push rods exactly where they came from. In order to protect the stems of valve along with pushrod ends from damage apply some engine assembly lube on them. For every rocker arm shaft as well as bearing make sure you apply clean engine oil then install loosely into original locations (where they were removed). Rotate crankshaft to TDC on compression stroke for number 1 piston then tighten intake valve rocker arms for specific cylinders. Rotate crankshaft 360 degrees then tighten intake valve rocker arms on other cylinders. At last put on valve covers start engine and listen for unusual noise coming from valve train and to check for oil leaks.

    Q: How do you remove the Pushrod and Rocker Arm on 4.3L V6 engine for Chevrolet Avalanche,Silverado,Suburban,Tahoe and GMC Sierra,Yukon,Yukon Denali,Yukon XL?
    A: You can start by removing the Rocker Arms, which will be loosened and stored in containers labeled as rocker arm support bars. Keep their different pushrods separately. If necessary, inspect each rocker arm for damage on the pivoting area and cracks or wear on the bearing surface; after that replace any defective ones, making sure roller bearings rotate freely. Look at the pushrods to see if they have cracks, are too worn out or bent. For reinstalling, lube the push rods and put them back into their original position with full seating in the lifter being noted. After that, place back the rocker arm support with arrows up and also wipe off grease from valve stems and ends of pushrods. Then fit all rocker arms one by one, lubricating roller bearings lightly and tightening the rocker arm bolts evenly according to a specified torque. Lastly, you can start your engine up and check it for oil leaks or noises from the valve train mechanism.
