INFORMATION

Overview







Preliminary work
1. Remove engine guard.

Removing (main) catalytic converter

CAUTION: Danger of burns from hot exhaust system.

- Only remove the exhaust system once it has cooled down.
- Wear protective gloves.

INFORMATION: Please read the most important working regulations and warning notes - The most important working regulations and warning notes.

1. Loosen the transmission support on the body and remove it.







1. 1. Support transmission. - Supporting transmission Use a transmission jack similar to the one shown if necessary.







1. 2. Unscrew screws in holder on the body and on the transmission support- Holder for main catalytic converter and loosen and remove transmission support -1-.

2. Remove main catalytic converter.







2. 1. Loosen connecting clamps between the main catalytic converters and the exhaust system.
Then push the clamps back onto the exhaust system. The exhaust clamps must not be reused.







2. 2. Loosen main catalytic converter at the primary catalytic converter -4- and remove it.

Installing (main) catalytic converter

INFORMATION: Replace seals, fastening nuts and clamp.

2. Install main catalytic converters.
2. 1. Move the main catalytic converters into installation position and fit the screws in the holder on the body.







2. 2. Fit main catalytic converters -4- on the primary catalytic converters. Use new screws.







3. Move new exhaust clamps for the exhaust system into installation position and fit them. The threaded joint must be facing downwards. Adjust to maximum transverse inclination and ensure the assembly length is the same on both exhaust pipes. - Installation position of exhaust clamp
4. Install and tighten transmission support.
5. Fit holder for catalytic converter on transmission support.
6. Tighten all screws to the correct torque. Main catalytic converter to primary catalytic converter - Tightening torque: 23 Nm (17 ftlb.); exhaust clamp - Tightening torque: 23 Nm (17 ftlb.); main catalytic converter to transmission support - Tightening torque: 23 Nm (17 ftlb.); main catalytic converter to body - Tightening torque: 23 Nm (17 ftlb.)

Subsequent work
1. Install engine guard.
