Refitting
- Fit the injectors in the seats in the camshaft housing.
To improve the operation of the engine and guarantee the emission limits, an injector classification criterion has been introduced. If the injectors are replaced the following must be taken into account:
- Tighten the bolts fixing the brackets.
| Value - daNm | Fastening | Component | Ø | |
|---|---|---|---|---|
| 2.5 | Bolt | INJECTORS(DIESEL) | M8 |
- Fasten the recirculation pipe on the injectors using securing bands.
See in Op. 1060F36
- Connect the electrical connections disconnected previously.

2. Disconnect the fuel recirculation pipe attachment.
3. Undo the fixing bolt (3a) and remove the injector (3b).
- Carry out the same operation on all the injectors
Refitting
- Fit the injector in place.
To improve the operation of the engine and guarantee the emission limits, an injector classification criterion has been introduced. If the injectors are replaced the following must be taken into account:
The Bosch number and class to which it belongs (1, 2, 3 or 2C inside a rim), which is determined according to the amount of fuel injected into the "emission" control point, is etched, by laser, on each injector on the top part of the magnet.
If an injector is being replaced, a new injector of the same grade must be fitted.
- Tighten the fixing bolt and check the torque.
- Connect the fuel return pipe.
