What is the Correct Method for Installing a Rocker Arm Assembly on Dodge Nitro?

Before installing the rocker arm assembly, set the rocker arms so the concave pocket faces the lash adjusters to avoid causing much damage. Just before you install the rocker arms, smear them with clean engine oil. When fitting the rocker arms on No.4, place the crankshaft so that cylinder No. 1 is set at intake bottom dead center. Crankshaft should be rotated for cylinder No. 1 until it is at BDC combustion point. Turn the crankshaft for cylinders No. 3 and No. 5 until you find cylinder No. 1 at top dead center during the exhaust stroke. Rotate the crankshaft so that cylinder No. 1 is at TDC for ignition which corresponds to cylinders No. 2 and No. 6 for positive leaf ignition. With the Rocker Arm Remover/Installer 8516A, press down on the valve spring and set the rocker arm in place. The last step is to fit the cylinder head cover.

How to Maintain the Left-Side Rocker Arm on Dodge Nitro?

Before you start servicing the rocker arm on the left side, take out the battery's negative cable so that the starter does not engage by mistake. Take out the cylinder head cover. Turn the crankshaft until cylinder No. 1 is reaching its bottom of the intake stroke during rocker arm removal on No. 4 cylinder. For cylinder No. 1, crank the shaft until it reaches bottom dead center combustion stroke. For these two, wait until cylinder No. 1 reaches TDC for the exhaust stroke and then continue. For both cylinders No. 2 and No. 6, turn the crankshaft so that cylinder No. 1 reaches its TDC ignition stroke. To remove the rocker, place the Rocker Arm Remover/Installer 8516A over the valve spring and press down.
