b) remove valve covers

1. Remove the plugs from the shield assembly.

2. Remove the bolts that hold shield (1) to manifold. Put the shield (1) to the side of manifold.

3. Remove tube (3) from the shields.

4. Install a 7/16"-14 NC forged eyebolt in hole (2).

5. Disconnect the elbows (5) from the shield.

6. Remove the bolts (6) that hold shields together.

7. Remove the oil line (4) from engine.

8. Install a 3/8"-16 NC forged eyebolt in shield. Fasten a hoist and remove water shield. Weight is 107 lb. (48 kg) on D379; 127 lb. (58 kg) on D398; 199 lb. (90 kg) on D399.

9. Remove the bolts (8) that hold manifold to turbocharger. Remove water line from back of shield.

10. Fasten a hoist to manifold. Remove the bolts (9) and brackets (10) that hold manifold to the cylinder heads.

11. Remove the exhaust manifold (11) and shield (7) as an assembly. Weight is 90 lb. (41 kg) on D379; 120 lb. (54 kg) on D398; 165 lb. (75 kg) on D399.

12. Remove the bolts (12) that hold shield to exhaust manifold.

13. Remove the shield (7) from manifold.

Install Exhaust Manifolds (Industrial Engines)

1. Put new gaskets on the exhaust manifold (2).

2. Install the shield (1). Tighten the bolts (3) to 10 lb. ft. (14 N·m).

3. Put 5P3931 Anti-Seize Compound on the threads of all bolts that hold exhaust manifold to cylinder heads and turbocharger.

4. Fasten a hoist to the exhaust manifold. Put the exhaust manifold in position on engine.

5. Put new gaskets between shield and cylinder heads. Install the bolts (5) and brackets that hold manifold to cylinder heads.

6. Install the bolts (4) that hold turbocharger to exhaust manifold. Tighten these bolts to 40 ± 4 lb. ft. (55 ± 5 N·m).

7. Install the water line (6) on the shield.

8. Put grease on the seal (7) and bore of water temperature regulator housing.

9. Install a 7/16"-14 NC forged eyebolt and a 3/8"-16 NC forged eyebolt in the water shield. Fasten a hoist and put the water shield on the exhaust manifold and elbow in the water temperature regulator housing.

10. Install the oil line (8) for the turbocharger lubrication valve.

11. Install bracket (11).

12. Install new gaskets for elbows. Install the bolts that hold elbows (9) to water shield.

13. Install the bolts (10) that hold the shields together.

14. Install the tube (12) on front of shields.

15. Put the shield (13) in position and install the bolts.

16. Install the plugs.

17. Fill the engine with coolant to correct level.

end by:

a) install valve covers

b) install fuel injection lines
