15. In
stallation of the exhaust system
See Fig. 40.
¿ Note: On the underside of the exhaust system, two different mounting mechanisms are
provided. At the front, the assembly is carried out with rubber buffers (pos. 7)
between the retaining plate (pos. 6) and the exhaust system and attached by
extension springs (pos. 8). At the rear, the exhaust system is mounted directly using
rubber mounts M8 (pos. 9).
¢ Attention: A rigid suspension of the exhaust system could result in fractures in the exhaust
system.
Æ Attach the heat-resistant rubber mounts (pos. 9) to the two support lugs on the
underside of the tuned exhaust.
Æ Arrange the chassis-specific supports so that the exhaust system follows the
straightest possible course from the exhaust socket on the cylinder to the muffler.
Æ The gasket (Pos. 13) is the only sealing between the engine and the exhaust
system. Additional heat-resistant Loctite is not necessary anymore.
¿ Note: All engine types have the same gaskets
¿ Note: A leakage in the exhaust system may lead to performance loss.
Æ Secure the exhaust system on the ball joint, using two supplied exhaust springs
(pos. 14).
¿ Note: For easier installation use the special tool "spring hook" part no. 251680.
¢ Attention: Do not overstress the springs when fitting them.
Æ Attach the exhaust system to the chassis supports such that the sealing of the ball
joint between cylinder and exhaust system will not be impaired.
