RING 5T6431 - Caterpillar

Assembly 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.
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.
Ensure that all components are clean and free from wear and damage. If necessary, replace any components that are worn or damaged.
Place the assembly of the Diesel Oxidation Catalyst (DOC) onto a suitable stand.

(5) Outlet section
Install new Torca clamp (2) and Torca clamp (4) onto DOC (1) and DPF (3) as shown in Position (A). Ensure that the Torca clamps are correctly orientated.
Attach a suitable lifting device to DPF assembly (3). The weight of the DPF assembly is approximately 66 kg (145 lb).
Use the suitable lifting device to position DPF (3) onto DOC (1).
Rotate DPF (3) in a clockwise direction in order to engage pins and slots (6).
Slide Torca clamp (2) along the DOC onto the DPF. Alignment the Torca clamp with temporary marks. Tighten the nuts on the Torca clamp hand tight.
Attach a suitable lifting device to outlet section (5). The weight of the outlet section is approximately 15 kg (33 lb).
Use the suitable lifting device to position outlet section (5) onto the DPF.
Rotate outlet section (5) in a clockwise direction in order to engage pins and slots (6).
Slide Torca clamp (4) along the DPF onto the outlet section. Alignment the Torca clamp with temporary marks. Tighten the nuts on the Torca clamp hand tight.

Ensure that Torca clamp (2) and Torca clamp (4) are correctly aligned with temporary alignment marks in Position (B) and Position (C). If necessary, adjust the alignment of the Torca clamps.
Ensure that Torca clamp (2) and Torca clamp (4) are correctly aligned with temporary alignment marks in Position (A) and Position (D). If necessary, adjust the alignment of the Torca clamps.
Tighten nuts for Torca clamp (2) and Torca clamp (4) to a torque of 42 N m (31 lb ft).
Install 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 - Install" for the correct procedure.
