ROCKER ARM AS 4582975 - Caterpillar

Installation Procedure
1. For engines with centrally mounted turbochargers, check the air piping to the turbochargers. The turbochargers must be correctly aligned and should not support excessive piping weight.2. Be sure the exhaust manifold and cylinder head surfaces that contact the exhaust manifold gasket are clean and free of any foreign material.3. Be sure the bolt holes in the cylinder heads have good threads. Also, be sure there is no dirt or fluid in the bolt holes.4. Loosen the bolts on the exhaust manifold expansion joints where the repair is being made (loosen all the expansion joint bolts if the entire manifold is being installed). Be sure the manifold sections can be moved in the expansion joints.5. Put the exhaust manifold and new exhaust manifold gasket in position on the cylinder head. If required, use a hammer and piece of wood to put the manifold into position against the cylinder head.6. Put 5P3931 Anti-Seize Compound on the exhaust manifold bolt threads before installation. Tighten the bolts to a torque of 55 7 N m (40 5 lb ft). After all the bolts are installed, tighten them again to the same torque.7. Put 5P3931 Anti-Seize Compound on the threads of the expansion joint bolts that were loosened. Tighten the bolts to 45 7 N m (32 5 lb ft).
