Dodge Magnum Rocker Arm
The Rocker Arm in Dodge Magnum vehicles plays a significant function in engines valve train mechanism as it ensures the conversion of movement of the pushrod to the intake and exhaust values. Usually made from stamped steel, aluminum or some high strength alloy, the Rocker Arm is designed to translate the oscillation or back-and-forth movement of the pushrod vertically into the kind of downward movement required to dilate the valves. Silicon alloy is used in high-RPM applications due to its low weight whereas cast iron or forged carbon steel is used in diesel engine for high durability. Some Dodge Magnum cars may have roller rockers that deploy needle bearing in the enhancement of the efficiency of the car as opposed to traditional metal on metal rolling. The rocker ratio which is standard in modern engines is between 1.5:1 and 1.8:1 enables increased camshaft lift and thus increases its efficiency. This is particularly applicable in high RPM engines of Dodge Magnum that include upgraded fulcrum bearings to fix stress/weight problems regarding the Rocker Arm and thereby increasing its performance and durability.

Dodge Magnum Rocker Arm Parts Questions & Experts Answers
- Q: How to remove and inspect rocker arms and lash adjusters in 2.7L V6 engine on Dodge Magnum?A:A universal shaft-type valve spring compressor will be required for this procedure. The only other alternative to accomplishing this task without the use of this special tool is to remove the liming chains and the Camshafts which requires major disassembly of the engine and surrounding components. Before beginning this procedure, be sure to place the transmission in Neutral and apply the parking brake or block the rear wheels. Also, disable the ignition system by disconnecting the primary electrical connectors at the ignition coils and remove the spark plugs. Remove the upper intake manifold and the valve cover(s). Rotate the engine with a socket and ratchet attached to the crankshaft pulley bolt until the cam lobe for the rocker arm to be removed is located on its base circle. Turn the crankshaft in a clockwise direction. Before the rocker arms and lash adjusters are removed, arrange to label and store them, so they can be kept separate and reinstalled on the same valve they were removed from. Mount the valve spring compressor on the cylinder head. Depress the valve spring just enough to release tension on the rocker arm to be removed. Once tension on the rocker arm is relieved, the rocker arm can be removed by simply pulling it out. If you're replacing or removing all of the rockers arms or lash adjusters, begin with cylinder number one and work on the rocker arms for one cylinder at a time. Move from cylinder-to-cylinder following the firing order sequence. Remember to keep the rocker arm and lash adjuster for each valve together so they can be reinstalled in the same locations. Once the rocker arms are removed, the lash adjusters can be pulled out of the cylinder head and stored with the corresponding rocker arm. Inspect each rocker arm for wear, cracks and other damage. Make sure the rollers turn freely and show no signs of wear, also check the pivot area for wear, cracks and galling. Inspect the lash adjuster contact surfaces wear or damage. Make sure the lash adjusters move up and down freely in their bores on the cylinder head without excessive side to side play. Installation is the reverse of removal with the following exceptions: Always install the lash adjuster first and make sure they're at least partially full of oil before installation. This is indicated by little or no lash adjuster plunger travel.
