Note! t
| If fitting a new injector-pump unit, the corresponding adjustment bolt on the rocker must also be replaced. |
t
| Any time work requiring adjustment of the injector-pump unit is carried out, clean the adjustment bolt on the rocker and the round-headed pin on the injector-pump unit, also checking for wear. If worn, the round-headed pin and the adjustment bolt must be replaced. |
t
| Apply -G 000 100- to the contact surfaces between the round-headed pin and the adjustment bolt. |

| New injector-pump units are supplied with their own O-rings and heat shield seal. |
–
| If the used injector-pump unit is refitted, replace the O-rings and the heat shield seal → Chapter. |
–
| Before assembly of the injector-pump unit, check the three seals, the heat shield seal and the safety washer for correct seating. |
Note! The seals must not be bent. |
–
| Oil the seals and fit the injector-pump unit very carefully in its seating in the cylinder head. |
–
| Pressing uniformly, seat the injector-pump unit all the way on to the cylinder head. |
–
| Fit the fixing block in the side slot of the injector-pump unit. |
Note! If the injector-pump unit is not perpendicular to the fixing block, the fixing bolt may come loose, and this could result in damage to the injector-pump unit or the cylinder head. |
–
| Therefore, the injector-pump unit must be fitted as follows. |
–
| Screw the new bolt into the fixing block until the injector-pump unit can still be turned slightly. |
