RIM AS 6G1528 - Caterpillar

Disassembly Procedure
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.Do not use power tools in order to disassemble or assemble any part of the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), or the outlet section.
Refer to Operation and Maintenance Manual, "Diesel Particulate Filter - Clean" before starting any maintenance procedures on the assembly of the Diesel Particulate Filter (DPF).
Remove the assembly of the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and the outlet section Clean Emission Module (CEM). Refer to Disassembly and Assembly, "Diesel Particulate Filter - Remove" for the correct procedure.
Place the assembly of the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and the outlet section onto a suitable stand.

(5) Outlet section
Loosen the nuts on Torca clamp (2) and Torca clamp (4) in order to allow Torca clamps to be moved.
Slide Torca clamp (2) and Torca clamp (4) along the DOC and the DPF.
Attach a suitable lifting device to outlet section (5). The weight of the outlet section is approximately 15 kg (33 lb).
Rotate outlet section (5) in a counter clockwise direction in order to disengage pins and slots (6).
Use the suitable lifting device to remove outlet section (5) from the DPF.
Remove Torca clamp (4) from DPF (3).
Attach a suitable lifting device to DPF assembly (3). The weight of the DPF assembly is approximately 66 kg (145 lb).
Rotate DPF (3) in a counter clockwise direction in order to disengage pins and slots (6).
Use the suitable lifting device to remove DPF (3) from DOC (1).
Remove Torca clamp (2) from DOC (1).
If necessary, clean the DPF. Refer to System Operation Testing and Adjustment, "Diesel Particulate Filter (DPF) - Clean" for the correct procedure.
