EXCERPT:
Testing Fuel Injector Nozzles
The injectors must be off of the engine before being tested.
Note: Refer to Special Instruction, SEHS7292, "Use Of 5P-4150 Nozzle Assembly" for more information.
Fuel Injection Lines
Fuel from the fuel injection pumps is sent through the fuel injection lines to the fuel injection valves.
Each fuel injection line of an engine has a special design. Each fuel injection line must be installed in a certain location. When fuel injection lines are removed from an engine, put identification marks or put tags on the fuel lines as the lines are removed. This will allow the lines to be installed in the correct location.
The nuts that hold a fuel injection line to an injection valve and to an injection pump must be kept tight. Tighten the fuel line nuts to 40 ± 7 N·m (30 ± 5 lb ft).
Fuel Bypass Valve
The fuel bypass valve controls fuel pressure to the fuel injection pump. At full speed, the pressure is limited to 230 ± 35 kPa (33 ± 5 psi).

Check Set Point (Balance Point)
An engine relies on set point for the correct operation of the engine. The set point check
of the engine is a method that will diagnosis engine performance.
There is a new, more accurate method for checking the set point of the engine. Review
the required tools for the new method. If these tools are not available, you can use an
alternative method for checking set point.

Engine Protection Devices
Shutoff and Alarm Systems
Shutoff and alarm systems are either electrically or mechanically operated. The operation of all electric shutoffs and alarms utilize components which actuate switches in a sensing unit.
Shutoff switches are set at a more critical operating temperature, pressure, level or speed than the alarm components. A shutoff switch opens or closes the circuit to the fuel shutoff solenoid. Opening the circuit to the fuel shutoff solenoid moves the fuel rack to the FUEL OFF position. The particular shutoff may require resetting before the engine will start.
When any sensing switch shuts the engine down, the problem causing the shutdown must be corrected before attempting to restart the engine.
Familiarize yourself with the:
* types and locations of the shutoff controls
* conditions which cause each control to function
* resetting procedure required to restart your engine
Alarm switches consist of a sensor and contactor. Examples of sensors are the magnetic pickup for detecting speed, and the pressure and temperature sensors. Sensors are wired to contactors. The contactors activate alarm circuits in the Annunciator Panel.
Alarm switches are set at a less critical operating temperature, pressure, level, or speed than the shutoff components. The purpose of the alarm switches is to warn the operator that an unsafe operating condition is beginning to occur.
When an alarm is activated, corrective measures must be taken, before the situation becomes an emergency, to avoid possible engine damage.
If corrective measures are not taken within a reasonable time, engine damage could result. Alternatively, a corresponding shutdown device (if equipped) will stop the engine.
The alarm will continue until the condition is corrected or the alarm is reset by the operator. The alarm circuits merely warn the operator, they do not shut the engine down to protect it from damage.
