8.4.2. Main and average mufflers
Average and main mufflers at the plant are installed in the form of an integral design. The faulty main muffler can be replaced and separately.
If it is necessary to replace the average muffler, then at the installed one-piece final pipeline it is necessary to change also the main muffler. If the main muffler was replaced already once, it is possible to replace the average muffler separately.
