Removal Procedure



Illustration 1g01335864
Typical example

  1. Remove bolts (2) that secure exhaust elbow (4) to the engine. Remove exhaust elbow (4) from the engine.

  2. Remove coupling (1) that connects exhaust elbow (4) to turbocharger (3).

  3. Some types of exhaust elbow have a separate support bracket. If necessary, remove the bolts that secure the bracket to the exhaust elbow. Remove the support bracket.

Installation Procedure



Illustration 2g01335864
Typical example

  1. Thoroughly clean exhaust elbow (4), coupling (1) and outlet of turbocharger (3). Inspect the sealing faces of the components for wear or damage. Replace any components that are worn or damaged.

  2. Install coupling (1) to exhaust elbow (4).

  3. Align coupling (1) to the outlet of turbocharger (3). Install assembly of coupling (1) and exhaust elbow (4) to turbocharger (3).

  4. Some types of exhaust elbow have a separate support bracket. If necessary, install the bracket and install the bolts that secure the bracket to the exhaust elbow finger tight.

  5. Install bolts (2) finger tight.

  6. Ensure that coupling (1) is fully engaged into the outlet of turbocharger (3) and into exhaust elbow (4). Ensure that the gap between the turbocharger and the exhaust elbow is evenly spaced.

  7. Tighten bolts (2) to a torque of 44 N·m (33 lb ft).

  8. If the exhaust elbow has a separate support bracket, tighten the bolts that secure the bracket to the exhaust elbow to a torque of 44 N·m (33 lb ft).
