for the former 1U6680 Governor and Fuel
Adjusting Tool Group.
Fuel Setting Check
Fuel setting is the adjustment of the fuel setting screw to
provide a specified injector rack position measured on the No.
1 injector rack bar. The fuel setting screw limits the power
output of the engine by setting the maximum travel of all the
injector racks.
Before the fuel setting is checked, the injectors must be
correctly
synchronized.
See
the
subject
Injector
Synchronization.
NOTE:
This procedure is illustrated with the No. 1
cylinder rocker arm assembly installed. Greater
access to the injector rack and control linkage is
provided, however, when the No. 1 rocker arm
assembly is removed. Instructions for removing
the rocker arm assembly are given in subject
Injector
Synchronization,
Steps
2
and
3.
Checking
valve
lash
and
fuel
timing
is
recommended after the rocker arm assembly is
reinstalled.
NOTICE
The injector spring must be slightly compressed to allow
free movement of the injector rack. Either the rocker arm
assembly or the 1U6675 Injector Spring Compressor
MUST be installed on all injectors to allow free movement
of injector racks.
