Usage:
Start By:
a. remove turbocharger
Typical Example
1. Disconnect hose (1) from the manifold assembly.
Typical Example
2. Fasten Tooling (A) and a suitable lifting device to each end of the exhaust manifold as shown. Remove bolts (2) and bolts (4) to remove elbow (3) and the exhaust manifold as a unit from the engine. The weight of the unit is 32 kg (70 lb).
3. Do Step 2 for the opposite side of the engine.
4. Remove elbows (3) from the exhaust manifold.
Typical Example
5. Remove vent line (7). Remove two bolts (5) and manifold assembly (6) from the rear of the engine.
NOTE: The following steps are for installation of the exhaust manifolds.
6. Put manifold assembly (6) in position and install bolts (5). Do nottighten the bolts at this time.
7. Install vent tube (7).
8. Put the gasket and elbow (3) in position on the exhaust manifold. Install the bolts to hold the unit together. Do nottighten the bolts at this time.
9. Fasten Tooling (A) and a suitable lifting device to the exhaust manifold as shown. Put the exhaust manifold and the gaskets for elbow (3) and the exhaust manifold in position. Install bolts (4) and tighten them to a torque of 43 ± 7 N·m (32 ± 5 lb ft).
10. Connect hose (1) to the exhaust manifold.
11. Install bolts (2) that hold elbow (3) to the rear manifold. Do nottighten the bolts at this time.
12. Repeat Steps 8 through 11 for the opposite side.
Typical Example
13. Tighten the exhaust manifold bolts in letter sequence as follows:
a. Make sure bolts (A) are tightened to a torque of 43 ± 7 N·m (32 ± 5 lb ft).
b. Tighten bolts (B) through (D) to a torque of 1 N·m (1 lb ft)finger tight.
c. Tighten bolts (B) through (D) to a torque of 14 ± 7 N·m (10 ± 5 lb ft).
d. Tighten bolts (B) and (C) to a torque of 43 ± 7 N·m (32 ± 5 lb ft).
e. Tighten bolts (D) to a torque of 100 ± 14 N·m (75 ± 10 lb ft).
NOTE: For more detailed information regarding the exhaust manifolds, see the topic "Exhaust Manifolds" in the Specifications Manual.
