Lambda probes and exhaust gas temperature control system (CCLA)
1. Nut: 3.5 Nm.
2. NOx sensor 2 control unit "J881" with NOx sensor 2 "G687"; tightening torque of NOx sensor 2 "G687" 50 Nm.
3. Main muffler.
4. SCR catalyst.
5. Exhaust pipe.
6. Diesel particulate filter.
7. Exhaust gas temperature sensor 3 "G495": apply heat-resistant paste to the sensor threads; 45 Nm.
8. Lambda probe "G39" with lambda probe heating element "Z19": new lambda probes are lubricated with mounting paste; when using lambda probes, only the threads may be lubricated with heat-resistant paste; mounting or heat-resistant paste should not get into the grooves of the lambda probe housing; 50 Nm.
9. NOx sensor control unit "J583" with NOx sensor "G295"; nOx sensor "G295" tightening torque: 50 Nm.
10. Nut: 3.5 Nm.
11. Control line of the differential pressure sensor "G505": screw to the exhaust pipe with a torque of 45 Nm; secure the hose to the pressure sensor with a clamp; do not change the curved shape of the discharge pipe; install freely.
12. Bolt: 4.5 Nm.
13. Differential pressure sensor "G505": after replacement, adjustment must be made.
14. Exhaust gas temperature sensor 4 "G648": apply heat-resistant paste to the sensor threads; 45 Nm.
15. Turbocharger.
16. Exhaust gas temperature sensor 1 "G235": lubricate the threads with heat-resistant paste for bolts; 45 Nm.
Reducing agent injector "N474"
