How to remove, inspect, and install the rocker arm and Pushrod in 4.0L pushrod V6 engine on Ford Explorer?

Before removing the valve cover(s), loosen the Rocker arm shaft support bolts, in a turn of turn basis beginning with the middle bolt in order not to stripped the head by the pull of valve spring when loosening the bolt by hand. Remove the rocker arm shaft assembly from the cylinder head and, then, visually differentiate each shaft assembly so that it could be fitted back into the same place. Then, take out the push rods and put them on a holder making sure you have arranged them in a manner that will allow for easy reinstallation. Remove the pins from the rocker arm assembly and lay the pieces on the workbench that they will not be mixed up. Check each rocker arm to see that it is not worn, cracked, or damaged especially at the ends where it bears on the push rods and valve stems: oil passages should be open. Measure the wear on the rocker arm bore combined with the rocker shaft worn position and replace the defective part. The push rods should be examined for cracks and signs of wear; the entire length of these should be rolled between two flat surfaces in order to identify bending. If this is so, the plugs which can be seen, protruding from the ends of the rocker shafts have to be removed and new ones inserted after the old ones have been knocked out. Rocker assembly can now be assembled and areas that have friction with engine assembly lube and new cotter pins are fastened at the ends of the rocker shaft with the oil hole facing downwards. Before final installation of the push rods, be sure to apply engine assembly lube on both ends of the rods, if the rods are original ones, you must place them back to their original positions. Grease the rocker arm pads and replace the rocker arm along with its positions on the notches on the shafts and the ball ends in the push rods . Torque the rocker shaft support bolts in a turning sequence from the center bolt to the outside in a two turn increments to the required torque and in the same manner that was followed to remove them.

Ford Explorer Rocker Arm

The Rocker Arm in Ford Explorer automobiles is an engine valvetrain component with a critical operation since it is responsible for moving the valve lift from the pushrod. Usually made from stamped steel or aluminum these parts translate pushrod lateral movement into the correct amount of downward force to open the valves. In high rotating speeds further aluminum is used due to lightweight whereas cast iron or forged carbon steel is used in diesel engines for higher strength. Both the standard and roller types of Rocker Arms have been used in Ford Explorer models with the automobile manufacturers offering a wide range of the Rocker Arm styles. Roller rockers that use needle bearings thus increases the power advantage when used in both the overhead valve and the overhead camshaft engines. The rocker ratio which is 1.5:1 to 1.8:1 in today's engines acts to amplify the lift of the camshaft leading to improved performance. Higher-performance fulcrum bearings are also employed where levels of stress and the required engine speed are high, for example in the Ford Explorer.

We provide a wide range of Ford Explorer Rocker Arm at the best prices possible. If you need Ford Explorer Rocker Arm, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your door step with a fast delivery service.
