C13 Generator Set Engine Caterpillar

Removal Procedure

Start By:

1. Remove the inlet module (catalyst).

2. Remove DEF injector and mounting.

1. Connect the engine to Caterpillar Electronic Technician (Cat ET) before the DPF is removed from the engine. Once the engine is connected to Cat ET, then perform an ash service test. This test is a manual regeneration. Allow the DPF to cool before proceeding.

8. Put Identification Mark (X) on both sides of clamp (10) for installation purposes.

9. Put Identification Mark (W) on the diesel particulate filter (9) for installation purposes. Identification Mark (W) is showing the flow of exhaust gases through the diesel particulate filter (9).

10. Loosen clamp (10) and disconnect strap (11) from diesel particulate filter (9).

11. Use a suitable lifting device to remove diesel particulate filter (9). The weight of diesel particulate filter (9) is approximately 57 kg (126 b).

12. Discard clamp (10).

Installation Procedure

Note: When installing a new diesel particulate filter or a cleaned diesel particulate filter, an Ash Model 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 diesel particulate filter (9) in the reverse order of removal.
