On page 3-12, steps
relating to resolving the
problem of an incorrect
tachometer reading are
listed.
Read down the page
until you find “TACHOMETER
READING IS INCORRECT.” The
steps listed are shown in
the example page to the
right of this text.
In accordance with step 1,
you connect the STE/ICE-R
to the engine (TM 9-2320-
280-20), start the engine
(TM 9-2320-280-10), let the
engine come to normal idle
speed of 650 RPM (± 25 RPM)
and then move on to step
2.
In Step 2 you check the engine idle against the STE/ICE-R and find
that it is correct.
In Step 3 you check the tachometer RPMs against the STE/ICE-R
RPMs and find they do not match.
At this point,
some CORRECTIVE ACTION in Table 3-2, Unit
Troubleshooting,
will direct you to a specific detailed procedure
to solve the problem.
To find the procedure, refer to the table of
contents.
NOTE: Before attempting to repair or replace the tachometer, as a Unit
mechanic, you must:
a.
Determine the maintenance responsibility of repair or replacement of
the component.
b. If the task is at your echelon of maintenance responsibility, you must
identify the tools needed and the replacement parts required.
Refer to the Maintenance Allocation Chart (MAC) (appendix B) to determine
not only the maintenance responsibility of the item, but also to obtain an
estimate of the time required to perform the task, tools needed, and any
special notes/requirements necessary.
Refer to the Repair Parts and Special Tools
the EES kit for requisition data concerning
task.
