5034982 JOHNSON GASKET, EXHAUST TUBE

Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: It is possible to remove the exhaust manifolds without removing the air inlet manifold first. However, the procedure is more difficult. The aftercooler must be removed before the exhaust manifolds are removed.Note: The following procedures describe the removal of the 3508B exhaust manifold.
Illustration 1 g01116210
Remove bolts (2) that attach exhaust manifold (1) to the turbocharger.

3508B exhaust manifold
Remove bolts (3). Remove manifold (4) and sleeves (5). Note: Manifold (4) is not used on the 3512B exhaust manifold or the 3516B exhaust manifold.
Remove bolts (7). Remove bracket (10).
Attach a suitable lifting device to exhaust manifold (1). The weight of the exhaust manifold is approximately 47 kg (104 lb). Remove bolts (8) that attach the exhaust manifold to the cylinder heads. Note: The weight of the 3512B exhaust manifold is approximately 66 kg (146 lb). The weight of the 3516B exhaust manifold is approximately 92 kg (203 lb).
Remove the exhaust manifold. Remove exhaust manifold gaskets (9). Remove gaskets (6).
