Mopar 5184296AF Rocker Arm Valve

A universal shaft-type valve spring compressor is required for this procedure, as the only alternative involves major disassembly of the engine and surrounding components by removing the timing chains and camshafts. Before starting, ensure the transmission is in Neutral, the parking brake is applied or the rear wheels are blocked, and the ignition system is disabled by disconnecting the primary electrical connectors at the ignition coils and removing the spark plugs. Next, 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 positioned on its base circle, turning the crankshaft in a clockwise direction. Prior to removing the rocker arms and lash adjusters, label and store them to keep them separate for reinstallation on the same valves. Mount the valve spring compressor on the cylinder head and depress the valve spring just enough to relieve tension on the rocker arm, allowing for its removal. If replacing or removing all rocker arms or lash adjusters, start with cylinder number one and work on one cylinder at a time, following the firing order while keeping the rocker arm and lash adjuster for each valve together. After removing the rocker arms, pull the lash adjusters out of the cylinder head and store them with the corresponding rocker arm. Inspect each rocker arm for wear, cracks, and other damage, ensuring the rollers turn freely and checking the pivot area for any issues. Also, inspect the lash adjuster contact surfaces for wear or damage, confirming that they move freely in their bores without excessive side-to-side play. Installation is the reverse of removal, with the exception that the lash adjuster should be installed first, ensuring they are at least partially full of oil, indicated by little or no plunger travel.
