ELBOW A. 9L0994 - Caterpillar

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.

In certain applications, it will be necessary to install the assembly of the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and the outlet cannister as an assembly.
Follow Step 3.a through Step 3.l in order to install the DOC, DPF, and outlet cannister as an assembly (1) .
Position a new ball clamp (5) onto the inlet of DPF assembly (1) .
Attach a suitable lifting device to DPF assembly (1). The weight of the DPF assembly is approximately 66 kg (145 lb).
Use the suitable lifting device to position DPF assembly (1) onto the bracket for clean emission module (6) .
Align DPF assembly (1) with flexible bellows (7) .
Install ball clamp (5) onto flexible bellows (7). Tighten the ball clamp finger tight.
Position clamp (2) and clamp (3) onto DPF assembly (1). Install the nuts to clamp (2) and clamp (3) .Note: Ensure that the DPF assembly is correctly positioned on the bracket for clean emission module.
Tighten bolt for ball clamp (6) to a torque of 18 N m (159 lb in).
Tighten nuts for clamp (2) and clamp (4) to a torque of 18 N m (159 lb in).
Install the tube assemblies for the pressure sensor to the DPF assembly. Refer to Disassembly and Assembly, "Pressure Sensor (DPF) - Remove and Install" for the correct procedure.
Install the soot antennas to the DPF assembly. Refer to Disassembly and Assembly, "Soot Antenna - Remove and Install" for the correct procedure.
Install the temperature sensors to the DPF assembly. Refer to Disassembly and Assembly, "Temperature Sensor (DPF) - Remove and Install" for the correct procedure.
If necessary, install the Original Equipment Manufacturers (OEM) exhaust system to outlet cannister (4) of the clean emission module.Alternative Installation Procedure for the Diesel Particulate Filter
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.
