BRAKE & DIFFERENTIAL DRIVE GP 6Y3587 - Caterpillar

TYPE="LEVEL" DEPTH="1" @@@-->Removal Procedure
Start By:
Remove the aftercooler. Refer to Disassembly and Assembly, "Aftercooler - Remove and Install".
Remove the air inlet manifold. Refer to Disassembly and Assembly, "Air Inlet Manifold - Remove and Install".
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 weight of the exhaust manifold is approximately 106 kg (234 lb).
Illustration 5 g00616615
Use a suitable lifting device to lift exhaust manifold (6) onto the engine.
Illustration 6 g00616613
Install new gaskets (5). Put Tooling (A) on the threads of the bolts and the washers that hold exhaust manifolds to the cylinder head. Install bolts (4), the nuts, and the washers. Tighten diagonal bolts simultaneously. Tighten the bolts to a torque of 55 5 N m (40 4 lb ft).
Illustration 7 g00616580
Install a new gasket for the joint between the exhaust manifold and the elbow for the turbocharger. Put Tooling (A) on the threads of the bolts and the washer faces. Tighten the nuts to a torque of 55 5 N m (40 4 lb ft).
