NOTICE
Do not allow dirt to enter the fuel system. Thoroughly
clean the area around a fuel system component that
will be disconnected. Fit a suitable cover over any
disconnected fuel system components.
Before starting this procedure, the Fuel Injection
Pump (FIP) driveshaft should be locked by reversing
the lock pin. Refer to the Disassembly and Assembly,
“Fuel Injection Pump - Remove” for more information.
Turn the valves for the fuel lines (if equipped) to the
OFF position before performing this maintenance.
Place a tray under the fuel injection pump to catch
any fuel that might spill. Clean up any spilled fuel
immediately.
Recommendations are that the screen is replaced
along with rubber gasket at every (500 hours)
scheduled fuel filter replacement. Inspection can be
done to check on the accumulation of particles in the
aluminum bowl to determine if the screen needs to be
changed and the interval frequency. The screen can
be cleaned using diesel fuel / air from inside out.
Ensure that the diesel fuel used, meets the required
specification. Refer to the Operation and
Maintenance Manual, “Fluid Recommendations” for
more information.
