GENERAL INFORMATION

At the factory, the rear pipe and the 2 mufflers form a single assembly. However, the mufflers can be replaced separately. Separate the mufflers by cutting with a standard chain saw, e.g., HAZET 4682. If the specified tool is not available, a hacksaw can be used.

4682. If the specified tool is not available, a hacksaw can be used.

CAUTION

If the muffler does not come out of the clamp, there are two options for removing it: cut the pipe 5 cm behind the clamp, then knock off the remaining pipe stub with a chisel and hammer. Second option: if a gas cutting torch is available, heat the clamp. The pipe will expand, allowing removal. Before using the torch, cover the underbody with asbestos cloth. Never heat the muffler in the area of the plastic fuel tank. Risk of fire. Keep a fire extinguisher ready.

Removal of Center/Intermediate Muffler When Combined as One Assembly

CAUTION

Risk of injury when lifting and supporting the vehicle on stands! Therefore, first read the chapter Jacking and Supporting the Vehicle.

PROCEDURE

1. Raise the vehicle and support it on stands.

2. The separation point of the muffler is marked by recesses. Separate at the center marks (arrow 2). The side marks (arrows 1 and 3) serve as depth indicators for inserting the pipes into the clamp.

3. Place the splitter chain around the center marks –2– and tighten. Roll the chain in both directions while tightening it to prevent pipe deformation during cutting.

4. Disconnect the muffler from the rubber hangers and remove it. INSTALLATION

5. Insert the muffler into the rubber hangers.

the applicable parts.

7. Align the exhaust system, refer to Exhaust System Removal and Installation.
