During all work on the exhaust system, the machine must be absolutely secure against movement in the raised state so that it cannot tip over in case of shocks, even if the pipes are rotated or pulled.
If a threaded connection cannot be removed during dismantling, it must be torn off by twisting. When assembling, install new screws and nuts.
Just in case, the locking rings are also replaced.
Exhaust pipe connections are best disconnected when hot. The workshop uses a welding torch or blowtorch for this purpose.
If the pipes are cold, then a rust-dissolving agent is used to separate them.
Pipes are separated using strong rotational movements or hit with a hammer.
If these techniques do not help, then the pipe connections of the damaged muffler are sawn in a place that is 10 cm further than the junction.
The rest of the pipe is sawn with a hacksaw in the longitudinal direction and removed with a powerful screwdriver.
The threaded connections of the exhaust system are easier to separate if the threads were lubricated with graphite paste during assembly.
The places between the joints can be lubricated with graphite paste, then it is easy to disassemble later.
When assembling, pay attention to the interface of all parts of the system (there should be no pressure).
Temporarily connect the parts together, install fixing brackets on the tubes, adjust.
Suspend the exhaust system with its fixing rings to the body.
Rubber holders must experience uniform, tensile forces.
A sufficient distance must be maintained from the exhaust system to the body. By shifting or turning, position the pipes and mufflers in the longitudinal direction so that they are at the same distance from the body. Between buffer (not all models) the rear muffler and the bottom of the trunk must maintain a certain clearance.
Only after the installation of the exhaust system has been adjusted can the screw connections be finally tightened.
If, during a test drive, it is found that the exhaust system is still rattling somewhere, it is necessary to disconnect the clamps again (Caution: Pipes may be hot!) and recheck the installation of the exhaust system.
Instruction. If, when installing the exhaust system, its parts were installed with a large interference fit, then extraneous noise appears. In addition, internal stresses can contribute to the appearance of cracks. Small leaks at one of the connections of the new exhaust system can be repaired by applying a sealing agent.
