TWO-WRENCH SQUEEZE METHOD2. Remove the injection nozzle clamp (2).3. Lift the injection nozzle (3) out of the cylinder head.
Pull nozzle straight out, by hand, to remove. Slight twisting action is permissible if necessary. Never attempt to pry out a nozzle with a screwdriver or other similar tool.
INJECTION NOZZLE REMOVAL (Left side illustrated)
1. Lines (eight, four each side). 2. Clamps (eight, four each side). 3. Injection nozzles (eight, four each side).4. Use needle-nose pliers to remove carbon seal dam (5). Always install a new compression seal (4) and carbon seal dam (5) before installing injection nozzle.
REMOVING CARBON SEAL DAM
4. Compression seal. 5. Carbon seal dam.Install Fuel Injection Nozzles
1. Be sure the bore in the cylinder head, fuel inlet fittings and the gasket surfaces are clean. Dirt or burrs on gasket surfaces can cause body distortion, resulting in a sticking valve.
Never install an injection nozzle that has been dropped, without first testing it with the 8S2242 Nozzle Tester Group. The injector tips are very hard and brittle and break easily.
2. Install a new compression seal and carbon seal dam. Use carbon seal dam installation tool (6) to install the carbon seal dam.
INSTALLING CARBON SEAL DAM
6. 8S2252 Carbon Seal Dam Installation Tool. Install a new grommet (7) before reinstalling an injection nozzle.3. Lubricate the exterior surface of cap (8). Pull grommet (7) over cap (8) in the direction indicated by the arrows.4. The shaded area shows grommet (7) correctly installed: Rotate grommet (7) so the flat surface will face the valve cover when nozzle is installed into cylinder head.
INJECTION NOZZLE
7. Grommet. 8. Protective cap. 9. Protective cap. A. Groove in grommet. Groove (A) to be installed in the half-moon cut-out provided in the valve cover mounting pad of the cylinder head.5. Coat groove (A) of grommet (7) with 7M7260 Liquid Gasket. Remove caps (8) and (9) and install nozzle (3) into cylinder head using a twisting motion. Do not use lubricant in the cylinder head bore or on the nozzle body.
Do not bend the injector inlet connection when installing injector into cylinder head. Bending of the inlet connection creates tension on the injector and causes binding of the needle in the guide.
INSTALLING NOZZLE
2. Clamps (eight, four each side). 3. Injection nozzles (eight, four each side).6. Assemble and tighten clamp (2) to hold nozzle (3) in place. Connect fuel lines to nozzle (3) and hand tighten connector nuts.7. Install rocker arm assembly. Install retaining bolts and locks. Tighten bolts to 18 5 lb. ft. (2.5 0.7 mkg) and bend locks. Install fuel return manifold.8. Adjust the intake valve clearance to .015 in. (0.38 mm) and the exhaust valve clearance to .025 in. (0.64 mm).9. Install valve cover. Install mounting bolts and tighten to 120 24 lb. in. (138 28 cm.kg).10. Purge fuel lines of air by motoring the engine until fuel, free of air, flows from the connections.11. Tighten the fuel line connections using the one-hand, two-wrench squeeze method as illustrated.
TWO-WRENCH SQUEEZE METHOD12. Start the engine and correct any fuel leaks that may occur.Disassemble Fuel Injection Nozzle (9L8965 and 9L9263 Nozzles)
Do not disassemble the nozzle unless testing indicates that servicing is necessary. See the TESTING AND ADJUSTING section of the Service Manual. Do not clean or readjust a nozzle that has excessive return leakage. Excessive return leakage is a sign of impending major nozzle failure that cannot be corrected by cleaning or adjusting and can possibly result in serious engine damage.
Use extreme care in keeping the work area and tools clean. Handle all parts with care to avoid any damage.
1. Place the nozzle in the holding tool (2) and secure the tool in a vise. Do not clamp any part of the nozzle body directly in the vise.2. Loosen pressure adjusting screw locknut (1).
REMOVING LOCKNUT (Typical Example)
1. Locknut. 2. 8S2250 Nozzle Holding Tool.3. Holding the nozzle in one hand, invert it and back out the pressure adjusting screw allowing the spring, spring seats and ball washer to fall into your hand. The valve may slide out, by its own weight, and should be handled carefully by its stem.4. If the valve does not fall out, remove it with retractor (3). To prevent bending the valve, bottom it in the body with the retractor. Push down on the retractor body to mount the collet. Turn the knurled nut counterclockwise to secure the collet and withdraw the valve.
LOCKNUT REMOVED (Typical Example)
REMOVING VALVE
3. 8S2254 Valve Retractor.5. Place the parts in solvent to loosen carbon and deposits of foreign material. Do not soak the body assembly in solvent for over 1 to 2 hours. The solvent can damage the epoxy bond used to secure the body assembly components together.Assemble Fuel Injection Nozzle (9L8965 and 9L9263 Nozzles)
Before assembly, wash all parts thoroughly. Flush the body to remove any debris or lapping compound. Assemble while all parts are wet with clean fuel.1. Handle valve (1) by its shank and slide it partially into the body.2. Assemble ball washer (5), spring upper seat (4), spring (3) and spring lower seat (2) to the lift and pressure adjusting screw assembly (6).3. Tilt the nozzle body and with spring lower seat (2) in contact with the top of valve (1), as illustrated, push the valve and spring components into the body.
Be careful not to dislodge spring lower seat (2) during assembly.
ASSEMBLING NOZZLE (Typical Example)
1. Valve. 2. Spring lower seat. 3. Spring. 4. Spring upper seat. 5. Ball washer. 6. Lift and pressure adjusting screw assembly.4. Tighten the adjusting screw assembly (6) by hand until the spring compresses with enough force to hold all the parts in place (8 to 10 turns).5. Adjust valve lift, opening pressure and tighten the locknut. See covering topics.Service And Inspect Fuel Injection Nozzle (9L8965 and 9L9263 Nozzles)
1. Use the brush (4) to clean the tip and body exterior.
CLEANING TIP
1. 8S2256 Pin Vise.2. Secure the 8S2247 Cleaning Wire [.008 to .009 in. (0.20 to 0.23 mm) dia.] in pin vise (1) with 1/32 in. (0.79 mm) to 1/16 in. (1.59 mm) of wire
