INSTALLATION PROCEDURE
Install the bracket as follows (see Figures 1-5):
PERSONAL INJURY
To avoid injury before starting and running the engine, ensure
the vehicle is parked on a level surface, parking brake is set, and
the wheels are blocked.
1. Loosen and remove the outside nut that is resting on the outside face of the stud bracket.
See Figure 1.

2. Loosen and remove the bolt from the positioning clamp which holds the gas inlet pipe to the throttle
shutoff valve and remove the clamp. See Figure 2.

3. Gently pull the gas inlet pipe from the center piece of the exhaust manifold and the throttle shutoff
valve. Note the arrows highlighting the affected areas in Figure 3.

5. Remove the two throttle shutoff valve mounting bolts and then the throttle shutoff valve.
See Figure 5.

6. Slide out the EGR connector pipe from the EGR cooler.
7. Install one of the wave springs into the EGR cooler inlet. Make sure the flat side of the wave spring is
facing out. See Figure 6.

8. Install one of the seal rings into the EGR cooler inlet against the flat side of the wave spring.
See Figure 6.
9. Inspect the EGR connector pipe assembly BEFORE installing it. There are four grooves on the
connector pipe assembly – two on each end.

NOTICE:
To avoid connector pipe damage, the Fey rings must be installed according to directions.
•Each groove contains two Fey rings, so there are a total of eight Fey rings.
•Within each groove, make sure the Fey rings are staggered 180 degrees from each other.
•Make sure the Fey ring set in each groove are staggered 180 degrees from the Fey ring set in the
neighboring groove.
•The net effect is the Fey ring gaps are staggered 90 degrees at each end of the pipe assembly.
10. Install the new EGR connector pipe assembly into the EGR cooler.
11. Install the other wave spring into the throttle shutoff valve. Make sure the flat side of the wave spring
is facing out. See Figure 6.
12. Install the other seal ring into the throttle shutoff valve against the flat side of the wave spring.
See Figure 6.
13. Slide the throttle shutoff valve onto the new EGR connector pipe assembly. See Figure 6.
14. Install the two throttle shutoff valve mounting bolts and torque them to 35 N·m (26 lb·ft).
See Figure 5.
15. Install the air supply line to the throttle shutoff valve actuator and torque the nut to
25 N·m (18 lb·ft). See Figure 4.
16. Gently install the gas inlet pipe into the center section of the exhaust manifold and the throttle shutoff
valve. See Figure 3.
17. Install the positioning clamp and hand tighten the bolt. See Figure 2.
18. Install the outside nut on the stud bracket and torque to 25 N·m (18 lb·ft). See Figure 7.
19. Check the length of the stud and verify it is 219 mm (8.62 in). If not, adjust the stud to
219 mm (8.62 in). Reference the MBE4000 Service Manual (6SE412). See Figure 7.

20. Torque the positioning clamp to 12 N·m (9 lb·ft). See Figure 2.
PERSONAL INJURY
Diesel engine exhaust and some of its constituents are known to
the State of California to cause cancer, birth defects, and other
reproductive harm.
• Always start and operate an engine in a well ventilated area.
• If operating an engine in an enclosed area, vent the exhaust to the
outside.
• Do not modify or tamper with the exhaust system or emission
control system.
21. After all repairs are complete, start and run the engine to ensure it is operating properly.
