71121 Mercury HOSE ASSEMBLY, FUEL PUMP TO EXHAUST PLATE (12 5/8")

Wear goggles, gloves, protective clothing, and a National Institute for Occupational Safety and Health (NIOSH) approved P95 or N95 half-face respirator when handling a used Diesel Particulate Filter or Catalytic Converter Muffler. Failure to do so could result in personal injury.
The muffler, catalytic converter/muffler, and diesel particulate filter will become extremely hot during engine operation. A hot muffler, catalytic converter/muffler and diesel particulate filter can cause serious burns. Allow adequate cooling time before working on or near the muffler, catalytic converter/muffler and diesel particulate filter.
Do not strike any part of the assembly of the Diesel Particulate Filter (DPF). Do not allow any object to contact the internal element of the DPF. If the internal element of the DPF becomes damaged, the assembly must be replaced.
Removal Procedure
Illustration 1 g02073233
In certain applications, it will be necessary to remove outlet section (1) or the Diesel Oxidation Catalyst (DOC) from the Diesel Particulate Filter (DPF) in order to allow the removal of the DPF.
If necessary, remove the DOC. Refer to Disassembly and Assembly, "Catalyst (Diesel Oxidation Catalyst) - Remove and Install" for the correct procedure.
If necessary, remove the OEM exhaust tube assembly from outlet section (1) in order to allow the removal of the outlet section from the DPF.
Make temporary alignment marks on the edge of Torca clamp (2) and Torca clamp (5) in Position (B) and Position (D) .
Make temporary alignment marks in Position (A) and Position (C) across DPF (3), the DOC and outlet section (1) .
Make temporary marks (4) in order to show the direction of the exhaust gases.

Sufficiently loosen the nuts on Torca clamp (2) and Torca clamp (5) in order to move the Torca clamp.
Move Torca clamp (2) and Torca clamp (5) in direction (6) and direction (8) in order to allow the removal of DPF (3) .
Remove the nut from clamp (7). Position the clamp away from DPF in order to allow removal of DPF (3) .
Attach a suitable lifting device to DPF (3). The weight of the DPF is approximately 20 kg (44 lb).
Use the suitable lifting device to remove DPF (3) from the bracket for the clean emission module.
Remove Torca clamp (2) and Torca clamp (5) .
