Install Turbocharger (Industrial Engine)
1. Check gaskets for damage and make a replacement if necessary.
2. Install turbocharger (1) in position on the engine. Put 5P3931 Anti-Seize Compound on the threads of the bolts that hold the turbocharger to the manifold. Tighten the bolts to a torque of 40 ± 4 lb.ft. (54 ± 5 N·m).
3. Put the gaskets between the oil drain tube (3), the oil supply tube (2) and the turbocharger. Install the bolts that fasten the tubes to the turbocharger.
4. Install two hoses (4) on turbocharger and install clamps (5).
5. Install coupling (6) on the turbocharger.
6. Put exhaust elbow and support (7) in position on coupling, and put 5P3931 Anti-Seize Compound on the threads of the bolts. Install two bolts to hold support assembly in place.
Remove Turbocharger (Marine Engine)
start by:
a) remove air cleaner
1. Remove four bolts (2) and clips that hold the exhaust elbow to the turbocharger group (1). Remove elbow (3).
2. Remove tube assembly (4) from aftercooler and turbocharger.
3. Disconnect couplings from each end of tube assembly. Remove tube assembly (5) from engine.
4. Remove two bolts (7) and disconnect opposite end of tube from the cylinder block adaptor. Remove oil supply tube (6) and gasket from turbocharger.
5. Remove two bolts (9), turbocharger drain tube (8) and gasket from flywheel housing.
6. Install a strap and hoist on the turbocharger and remove four nut that fasten the turbocharger to the exhaust manifold and the four bolts that fasten the air lines group to the aftercooler.
7. Remove turbocharger (11), air lines group (10) and gaskets from engine. The weight of the unit is 100 lb. (45 kg).
8. Remove pipe assembly (12) from the turbocharger.
Install Turbocharger (Marine Engine)
1. Inspect O-ring seals on the pipes. Install new seals if needed. Put clean engine oil on the O-ring seal.
2. Install the pipe assembly (1) in position on the turbocharger (2).
3. Install a strap and hoist on the turbocharger (2) and put turbocharger and gasket in position on the exhaust manifold.
4. Put 5P3931 Anti-Seize Compound on the threads of the studs that hold the turbocharger to the exhaust manifold. Install four nuts. Tighten nuts to a torque of 40 ± 4 lb.ft. (54 ± 5 N·m).
5. Inspect the O-ring seal on the drain line tube and make a replacement if necessary.
6. Put the gasket (4) in place between oil drain tube (3) and the turbocharger. Install the two bolts that hold the oil drain tube to the turbocharger.
7. Put the gasket in place between oil supply tube (5) and the turbocharger. Install oil supply tube (5).
8. Put tube assembly (6) in position on engine and connect the couplings on each end of tube assembly to fittings.
9. Install tube assembly (7) between the turbocharger and the exhaust manifold.
10. Inspect the ring (8) on the elbow for damage and make replacements if needed.
11. Put the elbow (9) in position on the turbocharger and install the four clips and bolts to fasten it to the turbocharger.
