Section Il. TROUBLESHOOTING
2-5. General.
a. Purpose.
The information in this section is for
the use of support personnel in conjunction with, and
supplemental to the troubleshooting section in the
pertinent Organizational Maintenance Manual (TM 9-
2320-209-20/1). This information therefore provides
the continuation of instructions in the Organizational
Manual wherein a reference is made to direct support
and general support maintenance personnel for
corrective action.
b. Operation.
Operation of a transmission, transfer,
or power takeoff without a preliminary examination
can cause further damage to the components and
possible injury to personnel. Required inspection and
troubleshooting will eliminate further damage to
equipment and injury to personnel. Causes of faulty
operation in a unit or component can often be
determined without extensive disassembly.
c. lnspection.
Inspection after the component is
removed from the vehicle is performed to verify the
diagnosis made while the component was installed in
the vehicle, to uncover further defects or to determine
malfunctions if the unit or component alone is
received by the support organization. This inspection
is particularly important in the final case because it is
often the only means of determining the malfunction
without completely disassembling the component.
Refer to Chapter 2, section III for general cleaning,
inspection, and repair procedures.
2-6. Introductory Information.
a.
This section contains troubleshooting
information for locating and correcting most of the
operating troubles which may develop in the

help you to determine corrective actions to take. You
should perform the tests/inspections and corrective
actions in the order listed.

This manual cannot list all malfunctions that
may occur, nor all tests or inspections and corrective
actions. If a malfunction is not listed or is not
