MAINTENANCE OF THE HEMTT - OD1662 - LESSON 1/TASK 2
NOTE
Check the flywheel ring gear for broken or
damaged teeth before installing a starter motor.
After the old starter motor has been removed, SGT Elliott is ready to
install the replacement motor. This is done by inserting the starter
motor into the flywheel housing.
While PVT Jones supports it, she
installs two screws (5) (figure 30 on the previous page), washers (6),
spacer (7), and the locknuts (8) on the starter end of the support
bracket (9).
SGT Elliott then secures the starter motor with the
three screws (3) and lockwashers (4).
She tightens the locknuts (7)
and screws (5) and reconnects the starter Rotor cables and solenoid
wires.
SGT Elliott now reconnects the battery cables and checks the operation
of the starter motor following the procedures contained in TM 9-2320-
279-10-1.
After the starter motor operation has been checked, SGT
Elliott reinstalls the engine side panel and closes the engine cover
following the procedures contained in TM 9-2320-279-10-1.
b.
Fuel System Troubleshooting. For this system, we will follow SGT
Price as he troubleshoots the malfunction FUEL LEVEL GAGE DOES NOT
REGISTER OR REGISTERS INACCURATELY and reaches the conclusion that the
fuel level sending unit is defective and needs replacement.
Prior to
beginning the actual troubleshooting procedures, SGT Price
performs
the preliminary procedures that were cited in paragraph 2c on
pages 43
and 44. Once these procedures have been performed, SGT Price
is ready
to begin the actual troubleshooting procedures.
(1) Troubleshooting Procedures. This particular malfunction consists
of only one troubleshooting step that SGT Price will follow.
He
checks the fuel gage and sending unit. This is done by removing the
wire in the center of the sending unit (figure 31 on the following
page). He touches the wire to ground, then places the ENGINE switch
to the ON position.
Since the fuel gage reads full, this indicates
that the sending unit is defective and needs to be replaced.
