Ford Expedition Rocker Arm

Ford Expedition has a Rocker Arm that has a significant performance in the valvetrain system, it helps the pushrod translate the motion into the operation of the intake and exhaust valves. Usually made from stamped steel or aluminum, the Rocker Arm has the responsibility of changing the vertical motion of pushrods into the required pressure needed to pull the valves open. High rpm requires lightweight metals, thus aluminium while for low rpm engines such as diesel engines, cast iron or forged carbon steel are used due to their strength. Different types of Rocker Arms that exist in the current market for instance roller rockers comprise of needle bearings that eliminate friction therefore enhancing the performance of the unit. The rocker ratio of the new Ford Expedition engines varies between 1.5:1 and 1.8:1, thus, camshaft lift is increased to enhance performance. Other enhancements that are used in the fulcrum bearings include the upgraded bearings to deal with pressure in high-RPM engines and improve the general Rocker Arm system strength.

    Q: What are the steps involved in the removal, inspection, and installation of the rocker arms and pushrods in V6 engine on Ford Expedition?
    A: Detach the valve cover(s) from the cylinder head(s). Starting at the front of one cylinder head, remove the rocker arm fulcrum bolts, which may not need to be completely removed in all cases; loosen them several turns to see if the rocker arms can be pivoted out of the way for pushrod removal. Store the bolts separately in marked containers to ensure they are reinstalled in their original locations. If only the pushrods are being removed, loosen each bolt just enough to allow the rocker arms to be rotated to the side for pushrod extraction. Lift off the rocker arms and fulcrums, storing them in marked containers with the bolts for proper reinstallation. Remove the pushrods and store them separately to avoid mixing during installation, using a perforated cardboard box for organization and labeling the front of the engine. Check each rocker arm for wear, cracks, and other damage, particularly at the contact points with the pushrods and valve stems. Ensure the hole at the pushrod end of each rocker arm is clear. Inspect the pivot area and fulcrum for wear, cracks, and galling; replace any worn or damaged rocker arms and fulcrums with new ones. Examine the pushrods for cracks and excessive wear at the ends, rolling each across a piece of plate glass to check for bending. Lubricate the lower end of each pushrod with clean engine oil or moly-base grease and install them in their original locations, ensuring each pushrod seats completely in the lifter. Apply moly-base grease to the ends of the valve stems and the upper ends of the pushrods before positioning the rocker arms and fulcrums. Grease the fulcrums to protect the mating surfaces prior to engine oil pressure buildup, then set the rocker arms and guides in place, installing the fulcrums and bolts, and tightening the rocker arm bolts to specifications. Finally, install the valve covers, completing the installation in reverse order of removal.
