Installation Procedure
- Install DEF injector assembly (5) in the reverse order of removal.
Note: To maintain cleanliness, the protective caps must remain in place until the final fluid connections are made.
Note: Install gasket (4) so that the metal is toward the Diesel Particulate Filter Group.
- Replace gasket (4) with a new gasket. Replace seal (6) with a new seal.
- Apply Tooling (B) to the threads of bolts (3) .
- Tighten bolts (3) to a torque of 5.0 ± 0.5 N·m (44 ± 4 lb in).
- Retighten bolts (3) to a torque of 5.0 ± 0.5 N·m (44 ± 4 lb in). Turn an additional 90°±5°.
