111 — the Pipe of system of release
120/1 — Primary catalytic converter


 PERFORMANCE ORDER

  1. Details of installation of primary catalytic converter on models 163.113 (the series 612 engine) are shown on an illustration to which all references which are found in the text belong.
  2. Remove the lower section of a noise isolation.
  3. Having squeezed the Swede disk springs (see an illustration of the Detail of installation of forward section of system of production of the fulfilled gases on models 163.136 (the series 111 engine)), unbend the screw-driver a steel uvula and release spring connection of fastening of primary catalytic converter (120/1) to a pipe (111) forward sections of system of production of the fulfilled gases.
  4. Turn out a bolt (1) of fastening of primary catalytic converter (120/1)
  5. Remove the air cleaner.
  6. Release a collar of fastening of primary catalytic converter (120/1) to a turbocompressor (110).
  7. Remove the catalytic converter (120/1).
  8. Installation is made upside-down, - track reliability of a zashchelkivaniye of disk springs, you make tightening of a fixing collar after fixing of the catalytic converter on a basic arm.

Utilization of the failed catalytic converters has to be made with respect for legislative rules!
