Fuel Injection
Pump
The fuel injection pump (figure 5.7) is one of the most important components of the diesel
engine and, therefore, calls for the utmost caution in handling. Furthermore, the fuel injection
pump has been thoroughly bench·tested and should not be tampered with.
Speed (hertz) and timing adjustment are the only adjustments the servicing dealer can perform
on the injection pump. Other types of adjustments or repairs
~
be performed by a qualified
injection service shop.
figure 5.7: Fuel Injection Pump
NOTE: When servicing the injection pump, the injection shop must be
told that the pump is being used in a generator application. The injection
shop will have to remove a timing shim located behind the oval cover
attached to the lower side of the injection pump and replace the
governor spring with a propulsion spring. Once the injector pump is
set up to propulsion specifications, the generator governor spring
(PN#024585) and the timing shim (PN#032021) are reinstalled in the
injection pump and the pump remounted on the engine. Then set the
throttle for proper engine no-load speed. (Hertz)
To obtain long and satisfactory service from the injection pump, always use fuel which is
free from impurities and maintain a good fikration and water separation system between the
fuel tank and engine. Service this system regularly: the injection pump it saves will be your
own.
