Installing Gasket Between the Exhaust Flap Control Module (J883) and NOx Reservoir or Reduction Catalytic Converter
- Insert gasket - 2 - with angled tab - B - in the notch - A - on the NOx reservoir or reduction catalytic converter - 1 -.
- Insert exhaust flap manifold - 3 - with the retaining tab - C - in the notch - A -.
Installation Position of the Clamp Between the Exhaust Flap Control Module (J883) and NOx Reservoir or Reduction Catalytic Converter.
- Install new clamp so the clamping bolt is opposite the exhaust flap control module housing and the - 45° ± 10° - angle is maintained.
Clamping Sleeve Location
- When installing clamping sleeve, ensure that the bolt end - arrow - does not project beyond the lower edge of clamping sleeve:
• Threaded connection points toward the right.
• Tighten threaded connections equally to 23 Nm.
