Install the remaining parts of Tool B on the threadedrod assembly (item 6).
Lubricate the threads on (item 6).
Tighten nut (item 1) in order to remove the unitinjector sleeve. Do not use an impact wrench.
After the sleeve is removed, use the large 4C5552wire brush to remove dirt and sealant from the bore. Squirt isopropyl alcoholor brake cleaner into the bore to remove oil. Use paper towels and swabsto remove all debris from the bore. Ensure the injector bore and fuel railare clean and free from debris.
Any sealant, fuel, oil or debris willprevent the sealant from properly curing. Improper cleaning will lead toa poor sealing surface and leak path.

4C9507 Locktite 620 Sealant 1 Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Ensure the o-ring (8T7878) is in place on the2219777 sleeve installer
Place the 1785037 unit injector sleeve on ToolA.
Clean the sleeve with isopropyl alcohol and wipedry with as clean paper towel. Note: Make sure the sleeve is free ofall debris, oil and fuel.
Apply 4C9507 Locktite 620 sealant (shake wellbefore using, sealant can separate) to the upper land and lower land ofthe unit injector sleeve.
Surfaces to be sealed must be freeof oil, grease, fuel, etc.
Install the unit injector sleeve into the injectorsleeve bore.
Use a hammer to drive the sleeve into the headuntil the sleeve bottoms out.
Wipe all excess anaerobic from the injector borewith a paper towel and swab.
Stamp AH on the front left top of the cylinderhead near the HEP 8 pump to verify the rework has been completed.
Wait approximately two (2) hours atroom temperature (70F) before filling the engine with fuel or coolant.Longer curing time is needed at lower temperatures.Unit injectors ? Installation procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.

Tool A 1492955 Seal Protector 1
Tool B 1492956 Seal Installer 1
Install injection actuation pressure sensor. Torquethe sensor to 10 2 N m (88 18 lb in).
Install the fuel lines and fittings as needed.Torque to specifications.
Lubricate the O-Ring seals and the sleeve boreof the injector sparingly with clean engine oil.
Install injector in the cylinder head. Positionthe injector into the cylinder head. Use your hand to install the injectorinto the cylinder head. Install socket head bolt on the exhaust side ofthe hold down bracket. Tighten the exhaust side of socket head bolt untilthe bolt is seated. Install and tighten the inlet side of socket head boltto a torque of 12 1 N m (9 1 lb ft).
Install the valve mechanism cover. Refer to Disassemblyand Assembly, "Valve Mechanism Cover - Remove and Install".
If the o-rings are damaged and needreplaced.
Use Tool (A) and Tool (B) to install the upper high-pressure seal pack.
Install the upper seal pack first. Then installthe middle seal pack. Finally, install the bottom O-Ring Seal.
Install Tool (A) on the injector.
Use Tool (B) to install backup rings and O-ringseal on the unit injector. Lubricate the O-ring seals and
