C13 Engine for Caterpillar Built Machines Caterpillar

Removal Procedure

Show/hide table

Hot engine components can cause injury from burns. Before performing maintenance on the engine, allow the engine and the components to cool.

Show/hide table

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.

2. Disconnect band clamp (6) and remove inlet module (catalyst) (5).

Installation Procedure

Note: When installing a new inlet module (catalyst) or a cleaned inlet module (catalyst), a DOC reset must be performed. Refer to Special Instruction, REHS8180, "Aftertreatment Filter Maintenance on Tier 4 Final Products Equipped with a Diesel Particulate Filter (DPF), Diesel Oxidation Catalyst (DOC), and a Selective Catalyst Reduction (SCR) Filter" for the correct procedure.

1. Install inlet module (catalyst) (5) in the reverse order of removal.

      Typical Example

      Note: Do not use power tools in order to torque strap (2).

   2. Apply Tooling (A) to the threads of strap (2) along Distance (Z). Distance (Z) is 25 mm (1.0 inch) above the trunnion. Tighten strap (2) to a torque of 15 + 3 - 0 N·m (133 + 27 - 0 lb in).

      Note: Do not use power tools in order to torque band clamp (6).

   3. Verify that the cup of the Ball Joint (G) does not touch the radius of the Ball (F). Position band clamp (6) and hand tighten band clamp (6). Band clamp (6) should be in the center of the joint.

   4. Dimension (D) and Dimension (E) should be equal within 2.0 mm (0.08 inch). Repeat the measurements every 90° around band clamp (6). If necessary, adjust band clamp (6).

   5. Torque band clamp (6) to a torque of 35 ± 2 N·m (26 ± 1 lb ft).

   6. Apply Tooling (A) to the threads of temperature sensor (3). Tighten temperature sensor (3) to a torque of 45 ± 5 N·m (33 ± 4 lb ft).
