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.

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)

Installation Procedure




1. When installing a new inlet module catalyst, a

“ Diesel Oxidation Catalyst (DOC) Reset” must be performed. Refer to Troubleshooting, Service Tool Features or your Perkins distributor for more

information.









Viewed from the inlet module catalyst assembly.

2. Install a new clamp (1). Position the clamp to

Dimension (Y) of 30° ± 5°. Refer to Illustration 183









3. Install a new clamp (8). Ensure that the clamp is correctly orientated.
4. Install inlet module catalyst (4). Ensure that the
clamp (8) and clamp (1) are correctly seated on to the inlet module catalyst. Hand tighten the clamps.
5.Apply Tooling (A) to the threads of clamp (2) along Distance (Z). Distance (Z) is 25 mm ( 1.0 inch)
above the trunnion.

6. Tighten band clamp (1) to a torque of 60 N·m

(44 lbft). Ensure that the band clamp remains in the correct position. Refer to Illustration 184 for the correct position.

Note: Do not use power tools to torque the clamp.

7. Tighten band clamp (2) to a torque of 15 N·m

( 133 lb in).

Note: Do not use power tools to torque the clamp.

assembly.
8. Torque band clamp (6) to a torque of 35 ± 2 N·m (26 ± 1 lbft).
Verify that the cup of the Ball Joint (G) does not touch the radius of the Ball (F). Position band
clamp (8) and hand tighten the band clamp. The band clamp should be in the center of the joint.
Dimension (D) and Dimension (E) should be equal
within 2.0 mm (0.08 inch). Repeat the
measurements every 90° around band clamp (8). If necessary, adjust the band clamp.


Tighten tube nut (3) to a torque of 40 N·m (30 lbft) . Ensure that tube assembly (6) is not strained as the tube nut is tightened.


9. Install temperature sensor (7). Refer to

Disassembly and Assembly, Temperature Sensor (DPF Inlet, Flame Detect) - Remove and Install for the correct procedure.

10. Connect tube assembly (6) to the elbow adapter on inlet module catalyst (4) and to the hose

assembly.

11. Hand tighten tube nut (3) for tube assembly (6).

12. Tighten hose clamp (5) to a torque of 1.4 N·m ( 12 lb in).
