Removal of mufflers is carried out on a suspended car and braked by a parking brake. Disconnect the wire from the terminal «minus» battery. Remove the air filter (see sect. «Air filter»). Removing the steering gear of the car (see sect. «Steering gear»). Unscrew the bolts of the flange fastening of the exhaust pipe 7 (pic. 28), remove from the cushion 8 and disconnect it from the main silencer 6. Unscrew the bolts of the flange connection 4, remove the silencers from the suspensions and disconnect them from the exhaust pipe 1. To remove the exhaust pipes 1, unscrew the nuts securing to the bracket 2, remove the cover 3 of the bracket, unscrew the nuts fastening the pipe to the cylinder head and remove it from the studs.
Silencers are installed in reverse order.
On the first releases of cars, the connection of pipes and mufflers was carried out using clamps; mufflers were produced (main 6 and additional 5) separate nodes. Removal and installation are somewhat different from the above. To remove the main muffler, install supports under the rear suspension arms in the area of the spring supports. Lower the car until the springs begin to compress. They take out the luggage compartment shelf, fold the back of the rear seat forward, unscrew the nuts securing the rear shock absorber rods and raise the car until the rear suspension springs are released. Loosen the fastening clamps, remove the exhaust pipe and the main muffler from the hangers and take them out but separately.
Install in reverse order. Mounting clamps are installed with a connector: at the exhaust pipe to the right along the direction of the car, the main muffler - down, the additional muffler with the exhaust pipe - also down.
