• Highly carcinogenic material!
• The dust contained inside the DPF is particularly fine and therefore classified as highly dangerous to living beings.
• Before proceeding to any operation, wear:
  dust mask
  gloves
  goggles
• Do not allow any other operator who is not equipped with the above mentioned protective equipment to approach.

1. Obtain a new replacement KIT for the DPF filter or a replacement KIT with regenerated DPF filter from your spare parts service. 

 Important

• Before disassembling/assembling any sensors, see Par. 2.17.5 and 2.17.6
• See service letter 710023.
• Always replace the seal P upon every assembly.
• During disassembly, do not expose the DPF to the surrounding environment for a long time and store it in a sealed bag as soon as possible.
• During disassembly operations, avoid using electric screwdrivers as vibrations could release the dust inside the DPF
• Do not try to clean the DPF
• Do not blow with compressed air
• Do not release the DPF or the dust contained in it in the environment
• Dispose of the DPF only in authorised centres

2. Perform the operations indicated in point 1 of Par. 11.8.
3. Open the package of the DPF replacement KIT, taking care not to damage it.
4. Unscrew screw A and loosen clamps B, then remove the Delta-P sensor D.
5. Disconnect pipes C from their unions J and remove the Delta-P sensor D.
6. Unscrew and remove unions J.

7. Loosen clamps E and remove manifold N.

Fig. 11.20

8. Loosen clamp G and remove the DPF filter H.

9. Inspect the DPF filter to detect any visible signs of oil contamination.
10. Put the removed DPF filter in the plastic container supplied with the replacement KIT and send it to your spare parts service using the replacement KIT package.

NOTE: a residual value will be recognised depending on whether the used DPF is intact and recyclable or damaged and requiring a correct disposal.

11. Loosen the clamps Q and S and remove the manifold with DOC M from the flexible hose R.

Fig. 11.22

12. Fit the new manifold with the DOC filter M on the support T, inserting the flexible hose R inside the inlet of the manifold M.

Fig. 11.23

 Important

• Do not apply any tension during the assembly of components.

13. Before fastening the manifold M, it must be oriented in the same position as the previously installed DOC filter.
14. Tighten the clamp Q (tightening torque of 10 Nm).
15. Tighten the clamp S (tightening torque of 12 Nm).

Fig. 11.24

16. Insert the gasket P on the manifold with DOC filter M.
17. Insert the new DPF filter H inside clamp G.
18. Insert the DPF filter H on manifold M until reaching the gasket P.

Fig. 11.25

 Important

• Before fastening the DPF filter H, it must be oriented in the same position as the previous filter.
• Do not apply any tension during the assembly of components.

19. Fasten the DPF filter H with clamp E (tightening torque 12 Nm).

Fig. 11.26

20. Insert gasket P on the DPF filter H.
21. Insert manifold N on the DPF filter H until reaching the gasket P.

 Important

• Before fastening manifold N, it must be oriented in the original position.

22. Fasten manifold N with clamp E (tightening torque 12 Nm).

Fig. 11.27

23. Position support K in contact with support K1 and fasten clamp G (tightening torque 12 Nm).

Fig. 11.28

24. Screw unions J on the DPF filter H and position them about 20° away from the centre line (as in Fig. 11.30).

Fig. 11.29

25. Fix unions J (tightening torque see service letter 710015).

Fig. 11.30

26. Fit pipes C on unions J and fasten them with clamps B.
27. Fix the Delta-P sensor D on its support K by means of screw A (tightening torque 10 Nm).
28. Provide the machine owner with the warranty certificate of the new DPF filter KIT installed.
29. Perform the "DPF replacement" procedure to reset the ASH & SOOT through the relevant KOHLER diagnostic tool interfaced with the ECU.
