Safety Precautions:
Before starting the removal procedure, it is crucial to follow these safety precautions:
1. Hot engine components can cause burns. Allow the engine and components to cool down before performing any maintenance.
2. Wear appropriate protective gear, including goggles, gloves, protective clothing, and a NIOSH approved P95 or N95 half-faceator when handling a used Diesel Particulate Filter or Catalytic Converter Muffler. Failure to do so may result in personal injury.
Procedure:
Step1: Remove the temperature sensor for the catalyst inlet.
– Refer to the Disassembly and Assembly Temperature Sensor (Catalyst Inlet) – Remove and Install guide for the correct procedure.
Step 2: Disconnect the Original Equipment Manufacturer (OEM) exhaust system.
– Follow the OEM’s instructions to disconnect the exhaust system from the connection (3) on the Selective Catalyst Reduction (SCR) (5).
Step 3: Loosen the clamp assembly (1) for the flexible exhaust pipe (2).
– This will allow you to remove the flexible exhaust pipe from the SCR catalyst (5).
Step 4: Disconnect the clamps (4) from the SCR catalyst (5).
Step 5: Attach Tooling (A) and suitable lift equipment to the SCR catalyst (5).
– The weight of the SCR catalyst is approximately 53 kg (117 lb), so ensure it is correctly balanced during removal.
Step 6: Use the suitable lift equipment to remove the SCR catalyst (5).
– Take care not to strain the flexible exhaust pipe (2) during the removal process.
Step 7: Remove the clamp assembly (1) from the flexible exhaust pipe (2).
Step 8: If necessary, remove the flexible exhaust pipe (2) by following these steps:
a. Loosen the clamp assembly (7) for the flexible exhaust pipe (2).
b. Remove the flexible exhaust pipe (2) while ensuring it is not strained.
c. If needed, remove the cover (6) from the flexible exhaust pipe (2).
Step 9: If necessary, remove the clamps (4) by following these steps:
a. Make temporary marks on the clamps (4) for installation purposes.
b. Remove the clips (8) from the pins (9) and remove the clamps (4) from the bracket.
c. Repeat steps 9a and 9b to remove any remaining clamps (4).
Conclusion:
The Perkins 2806F engine Catalyst (SCR) removal procedure may be required for maintenance or replacement purposes. By following the step-by-step guide outlined in this article, you can safely remove the SCR catalyst while ensuring the proper handling of components and adherence to safety precautions. Always refer to the manufacturer’s instructions and guidelines for specific details regarding your Perkins 2806F engine Catalyst (SCR) removal procedure.
