2 INSTALLATION OF THE E3 ELECTRONIC UNIT INJECTOR Install the E3 injector as follows: 1. If the fuel system is contaminated: [a] Drain the fuel tanks and refill with clean fuel. Refer to section. [b] Replace both filters with new, and clean the fuel/water separator, if equipped. Refer to section. [c] Inspect fuel injectors for damage and replace as required. 2. If the coolant system is contaminated with fuel, flush and reverse flush the system. Refer to section. 3. If the oil system is contaminated, change the engine oil and filters. Refer to section. EYE INJURY To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 276 kpa (40 psi) air pressure. NOTICE: Leftover fuel must be removed from the injector bore before injector installation. If fuel is trapped between the top of the injector hole tube and the lower injector O-ring seal, it may seep down to the injector hole tube seal ring, causing swelling and possible seal leakage. NOTICE: Injector O-ring seals, injector washers and injector hold down clamp bolts are considered one-use items and cannot be reused. Any time an injector is removed, the two injector O-ring seals injector washer and injector hold down clamp bolt must be replaced with new parts. Failure to replace O-ring seals, injector washer and injector hold down clamp bolts can result in leakage. 4. Check to make sure the injector bore is thoroughly clean. NOTICE: The injector tube bore should be cleaned and inspected for damage before installation of the E3 Electronic Unit Injector. Refer to section.

3 NOTICE: Take extra precautions when cleaning the injectors sleeves in the cylinder head to ensure that debris does not enter the fuel supply or return galleries. Do not use power tools to clean the injector sleeves; use hand brush J and a rag. Do not use compressed air to blow out the debris in sleeves. 5. Install a new washer on the injector. NOTE: All external O-rings must be lubricated prior to installation into the cylinder head. 6. Apply a thin coat of clean fuel to the injector seal rings and install them in the injector nut ring grooves. Make sure the seals are properly seated. See Figure 1 E3 Injector Seal Rings. Figure 1 E3 Injector Seal Rings

4 7. Record the injector calibration code. See Figure Injector Body 2. Injector Calibration Code Location Figure 2 E3 Injector Calibration Code Location 8. Remove injector nozzle tip protector. 9. Install a new injector hold-down clamp washer. The curved side of the washer fits into a corresponding curved cup in the injector hold-down clamp. See Figure Hold-down Clamp 3. E3 Injector 2. Washer Figure 3 E3 Injector 10. Replace the injector hold-down clamp bolt with a new bolt. Align the hold-down clamp over the retaining bolt hole and install the new bolt into the injector clamp and torque using the procedure below. No additional torque of the bolt is necessary. See Figure 4. [a] Torque the bolt to 50 N m (37 lb ft).

5 [b] [c] Loosen the bolt 60 degrees (1/6 of a turn, or one bolt flat). Do not fully loosen the bolt. Torque the bolt to 35 N m (26 lb ft).+ 90 (1/4 of a turn). 1. Injector Hold-down Clamp 4.

Refer to section.

7 INSTALLATION OF INTAKE MANIFOLD Install the intake manifold as follows: NOTICE: It is necessary to completely seal the intake manifold to the cylinder head, due to the high pressure of the intake charge provided by the turbocharger. The arrow on the gasket must point to the front of the engine. Gasket eliminator can not be used with intake manifold seals. Failure to seal this interface will reduce engine performance. 1. Install three new manifold gaskets to the mating surfaces of the intake manifold with the arrow on the gasket pointing to the front of the engine. See Figure 7. Figure 7 Intake Manifold Gasket Orientation 2. Install bolts ten and eleven through the intake manifold and into the cylinder head and hand-tighten.

8 3. Install the ten remaining bolts through the intake manifold and into the cylinder head. Torque all of the intake manifold retaining bolts to N m (43-54 lb ft) in the proper torque sequence. See Figure 8. Figure 8 Intake Manifold Bolt Position and Torque Sequence 4. Install the intake manifold pressure sensor. Refer to Section. 5.

NOTICE: Do not use any type of lubricant on the inside of any air inlet hose or on the hose contact surfaces of the turbocharger compressor housing, CAC, CAC ducting or the intake throttle. Use of lubricant can cause the hose to blow off when the turbocharger builds boost pressure. 8. Install EGR mixer onto intake manifold. Refer to Section 9. Install intake throttle valve and adaptor onto EGR mixer. Refer to Section 10. Plug in the intake throttle valve wiring connector by pressing the connector into the body of the sensor until the locking tang snaps into place 11. Install the Exhaust Gas Recirculation valve (EGR).

10 NOTE: If the manifold moves while removing the guide studs, loosen all bolts and go back to step 4. NOTE: If guide pins are used verify gasket position before installing bolts. 6. Install mounting bolts and spacers in locations 1, 2, 3, 4, 5, and 6 and torque bolts to N m (41-49 lb ft). 7. Torque bolts to N m (41-49 lb ft) in locations 7, 8, 9, 10, 11 and Torque the four bellows clamps to N m (9-10 lb ft). NOTE: Ensure the bellows clamps are orientated correctly.

Position the head gasket on the block and install cylinder head guide studs (J 35784) at front and rear of the block. See Figure 12. NOTE: Effective with engine serial number 06R , Series 60 engines will use a new cylinder head gasket. The new gasket will be identified with a new part number and is a metal sandwich-type compared to a woven appearance. The new gasket must be used with the new style cylinder head bolts. See Figure 14 Figure 12 Cylinder Head Guide Studs

13 3. Lift the head into position with lift bracket (J A). See Figure 13. Lower it into place over the guide studs (J 35784) until it seats on the block deck dowels. See Figure 12. Figure 13 Cylinder Head Installation 4. Remove the guide studs. 5. Install the head bolts with special hardened washers, lubricating the threads and bolt-head contact areas with a small amount of International Compound #2, or equivalent. NOTE: Effective with engine serial number 06R , a new style cylinder head bolt will be used for all Series 60 On-Highway engines. The new bolt will be identified with a groove on top of bolt. See Figure 14. Torque the new head bolts to 298 N m (220 lb ft). The new head bolt can be used with the former cylinder head gaskets; the former head bolts cannot be used with the new head gasket. Former and new bolts must not be mixed. Figure 14 Bolt Identification For Series 60 Engines

14 6. Torque the cylinder head bolts to 298 N m (220 lb ft) following the sequence shown in Figure 15.

15 Figure 15 Cylinder Head Bolt Tightening Sequence NOTICE: Failure to repeat the cylinder head bolt torque tightening sequence can result in some head bolts losing their torque when others are tightened resulting in insufficient clamp load. 7. Repeat the torque sequence to verify all of the head bolts are torqued to specification. NOTICE: The hemispherical portion of the injector hold-down clamp washers must be installed facing the clamp (pointing down) in order to prevent damage to the washers. 8. Visually inspect each injector hole tube to ensure they are clean. Install the fuel injectors. Refer to section. Be sure the injector hold-down clamps are clear of the valve and injector springs. 9. Install the camshaft. Refer to section. NOTE: If a cylinder head other than the one removed from the engine, or if a resurfaced cylinder head is being installed, the three nuts retaining the adjustable idler gear must be loosened before installing and torquing the camshaft drive gear retaining bolt.

16 NOTICE: The camshaft drive gear-to-adjustable idler gear lash must be measured/adjusted before the rocker arm shaft assemblies are installed. 10.
