TEST
1. Governor
NOTE
Governor difficulties are usually indicated by speed variations of the engine.
However, it does not necessarily mean that all such variations are caused by the
governor. Therefore, when improper speed variations appear, the engine should be
checked.
a. Check the engine to be sure
all cylinders are firing. If
any cylinder is not firing,
replace the injector per
b. Check for binding that may
exist in the governor operating
mechanism or in linkage
between the governor and the
control tube.
c. With the fuel rod connected to
the injector control tube
lever, the mechanism should be
free from binding throughout
the entire travel of the
injector racks. If friction
exists in the mechanism, it
may be located and corrected
as follows:
(1) If injector rack (1)
sticks or moves too hard,
it may be due to the
injector hold-down
clamp (2) being too tight
or improperly positioned.
To correct this condition,
loosen the injector clamp
(2), reposition, and
tighten to 20-25 ft-lb
(2.7660-3.4575 kgm)
