1.1 remove front common rail pump unit (Fuel system)

1.1.1 disconnect battery clamp, negative pole

Explanation

Warning, battery clamp and negative terminalDo not disconnect the vehicle batteries until the DEF dosing system has completed the purgecycle.Before beginning to remove and/or disconnect any components, wait at least 5 minutes afterthe key switch is turned OFF for the aftertreatment DEF dosing system to purge DEF from thesystem.The purge cycle is an automatic process and does not require active intervention. Theaftertreatment DEF dosing unit creates an audible pumping noise during the purging process.

Electrical shock hazard: Never disconnect the battery clamp when the engine is running.Disconnecting the battery clamps while the engine is running may result in death, personalinjury, or equipment damage from electrical arching or damage to electronic components.Turn off the engine and place the ignition switch in the OFF position before disconnecting thebattery clamps.Do not place any tools or other materials on top of or close to the batteries. This can cause adangerous high-current short circuit and, in the worst case, a battery explosion. Keep allobjects away from the battery terminals.Always break the contact between the battery clamp and the negative terminal beforeworking on the vehicle. Working on a vehicle while the battery is connected may result inelectrical injury or damage.Always disconnect the battery at the negative terminal when performing service procedures.

Battery acid can cause chemical burns.If you come into contact with battery acid: flush your skin with water and/or apply bakingsoda or lime to help neutralize the acid.If battery acid comes into contact with the eyes, flush immediately with water and seekmedical attention.Wear protective clothing when handling any part of the battery.

Fuel vapors and spills are potential fire hazards.When opening a fuel system, fuel can escape. Collect the fuel during servicing and dispose ofit properly to avoid the risk of fire.Mixing other fuels, such as gasoline, alcohol or gasohol with diesel can produce an explosivemixture.

To avoid injury from fuel while performing service on any fuel-system-related component(s):Prevent fuel from leaking or dripping onto the starter motor.Check the fuel components for leakage very carefully.Clean spilled or leaked fuel.Keep people who are not directly involved in the servicing away from the immediate area.Wear protective clothing (including face shield, insulated gloves and apron).Keep the work area well ventilated to prevent build-up of volatile fuel vapors.Keep all potential ignition sources away from the fuel. This includes: excessive heat, openflames, cigarettes, sparks and electrical sources.

Do not touch any of the fluoroelastomer seals or O-rings if they have been exposed to atemperature of 315°C or higher. The material of this product does not burn but decomposesinto a charred, black, sticky substance. This decomposition may contain hydrofluoric acid.This is very aggressive and difficult to remove once it has contaminated the skin. Use PVC orrubber gloves until the decomposed material has been identified and/or removed. If thesubstance makes contact with the skin, contact a doctor immediately.

Blocking and/or clamping the fuel pipes can lead to severe engine damage. Never block or plug the common rail release valve output, as this can lead to severe rail andcommon rail pressure release valve damage. Cover the crankcase pressure sensor and make sure that it cannot come in contact with anyfuel or fuel vapors. 

Always work in a clean manner according to the Cleanliness procedures Clean the area before performing repairs. The smallest amount of dirt, debris and other contamination can cause serious damage tosystems and/or the engine. Immediately plug the openings of the fuel system. 

M035658 - 20/07/2020Prime fuel system

If the fuel injection pipes have beenremoved:

Visually check both injection pipeconnections for leakage during primingthe fuel system.

Immediately stop the engine if fuelleakage occurs and replace theleaking fuel injection pipe.

After performing fuel system service, prime the fuelsystem to remove air from fuel system lines andcomponents. Three priming options are available;however, hand priming should only be performed as alast resort when recommended tooling is not available.After priming, and before releasing the truck, check thedash for residual DTCs.

The engine must idle for five minutes afterpriming with the optional blender bypassedto prevent air entrained in the fuel lines fromdamaging the fuel injection system.If the optional fuel blender is not bypassed,it can take up to 30 minutes of idle time topurge air from the fuel system.

1. Priming with DAVCO Shop Pro MX 40/80 (BaseUnit) 

2. Priming with Mityvac MV7430 

3. Hand priming

1.2.12 check fuel leakage fuel injection pipe

Explanation

Warning, Fuel SystemEye contact: Rinse immediately with plenty of water, also under the eyelids, for at least 15minutes. Consult a doctor.Skin contact: Wash off immediately with plenty of water. If symptoms persist, consult adoctor.

Inhalation: Get some fresh air. If symptoms persist, consult a doctor.Ingestion: Rinse mouth with water and then drink plenty of water. Do not induce vomiting.Consult a doctor.

Fuel vapors and spills are potential fire hazards.When opening a fuel system, fuel can escape. Collect the fuel during servicing and dispose ofit properly to avoid the risk of fire.Mixing other fuels, such as gasoline, alcohol or gasohol with diesel can produce an explosivemixture.

To avoid injury from fuel while performing service on any fuel-system-related component(s):Prevent fuel from leaking or dripping onto the starter motor.Check the fuel components for leakage very carefully.Clean spilled or leaked fuel.Keep people who are not directly involved in the servicing away from the immediate area.Wear protective clothing (including face shield, insulated gloves and apron).Keep the work area well ventilated to prevent build-up of volatile fuel vapors.Keep all potential ignition sources away from the fuel. This includes: excessive heat, openflames, cigarettes, sparks and electrical sources.

Do not touch any of the fluoroelastomer seals or O-rings if they have been exposed to atemperature of 315°C or higher. The material of this product does not burn but decomposesinto a charred, black, sticky substance. This decomposition may contain hydrofluoric acid.This is very aggressive and difficult to remove once it has contaminated the skin. Use PVC orrubber gloves until the decomposed material has been identified and/or removed. If thesubstance makes contact with the skin, contact a doctor immediately.

Blocking and/or clamping the fuel pipes can lead to severe engine damage. Never block or plug the common rail release valve output, as this can lead to severe rail andcommon rail pressure release valve damage. Cover the crankcase pressure sensor and make sure that it cannot come in contact with anyfuel or fuel vapors. 

Always work in a clean manner according to the Cleanliness procedures Clean the area before performing repairs. The smallest amount of dirt, debris and other contamination can cause serious damage tosystems and/or the engine. Immediately plug the openings of the fuel system. 

M035658 - 20/07/2020Warning, fuel injection pipe

Do not reuse the fuel injection pipe if the Evaluate the injector back leak test in DAVIE cannot beperformed successfully.

The high-pressure fuel injection pipes are not intended to be reused indefinitely.The fuel injection pipes and connections must be checked properly before reuse.Damaged and / or incorrectly installed injection pipes can cause hot fuel leakage, flammablegases or vapors.

Highly pressurized fuel is present in the common rail, fuel injection pipes and other high-pressurefuel components when the engine is running and when the engine is switched off. The pressureleaks away slowly when the ignition is switched off.Wait at least one minute before performing maintenance on high-pressure fuel components.

M030466 - 22/02/2021Checking fuel injection pipe with DAVIE

Damaged and / or incorrectly fitted injectorpipes can cause hot fuel leakage,flammable gases and vapors. Immediately stop the engine or test if fuelleakage occurs. 

1. Start the engine and run it at idling speed.Visually check both fuel injection pipeconnections for leakage.

Immediately stop the engineif fuel leakage occurs andreplace the leaking fuelinjection pipe.

2. If no leakage occurs, run the engine at 1200 rpm.Visually check both fuel injection pipeconnections for leakage.

Immediately stop the engineif fuel leakage occurs andreplace the leaking fuelinjection pipe.

3. If no leakage occurs, perform the 'Evaluate theinjector back leak' test using DAVIE.

It is not necessary to install thecontainers for the MX-13 engine duringthis check.

Visually check both fuel injection pipeconnections for leakage.

During this test the railpressure builds up to 2500bar [36260 psi].Immediately stop the test ifexternal fuel leakage occursand replace the leaking fuelinjection pipe.

If the engine does not run or stallsand the test fails, repeat the test:

Operate the manual fuel liftpump a few seconds beforeand while starting the engine.Stop operating the manualfuel lift pump a few secondsafter the test has started.
