NOTICE：

Note: Valve springs must be replaced in pairs for the inlet valves or the exhaust valves of each cylinder. If all valve springs require replacement the procedure can be carried out on two cylinders at the same time.
The procedure can be carried out on the following pairs of cylinders. 1 with 6, 2 with 5 and 3 with 4.
Ensure that all the valve springs are installed beforechanging from one pair of cylinders to another pair of cylinders

Personal injury can result from being struck by parts propelled by a released spring force.
Make sure to wear all necessary protective equipment.
Follow the recommended procedure and use all recommended tooling to release the spring force.

Perkins EST Diagnostic Adapter- High Quality
WARNING:

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


WARNING:

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 Particu-
late Filter or Catalytic Converter Muffler. Failure to do so could result in personal injury.


1. To remove the inlet module (Catalyst), access to

the underside of the clean emission module will be required. Refer to the Original Equipment

Manufacturer (OEM) for the correct location and the correct procedure to gain access to the

underside of the inlet module (Catalyst).







2. Remove temperature sensor (7). Refer to
Disassembly and Assembly, Temperature Sensor (DPF Inlet, Flame Detect) - Remove and Install for the correct procedure.


3. Loosen hose clamp (5) for tube assembly (6). Disconnect tube nut (3) for the tube assembly. Remove the tube assembly from inlet module catalyst (4).


4. Sufficiently loosen clamp (1) and clamp (2) to allow removal of inlet module catalyst (4).


5. Sufficiently loosen band clamp (8) to allow removal of inlet module catalyst (4).

6. Remove inlet module catalyst (4)
