Personnel Required:
The number of personnel needed to perform a task. If only one mechanic is
needed, this heading will not be used.
NOTE
If you think that you need more help to adequately or safely
complete a task, perhaps as the result of unusual conditions, etc.,
alert your supervisor and ask for help.
Manual References:
Those TMs needed to complete the task.
Equipment Condition:
Notes the conditions that must exist before starting the task. If none are
required, this heading will not be used. For oil cooler assembly replacement, the left-hand engine
splash shield should be removed before we can start the task. If not already done, follow the
procedure for splash shield removal in para. 10-17, before proceeding with this task.
General Safety Instructions:
Summarizes all safety warnings for the maintenance task. If none
are required, this heading will not be used.
3.
A step by step maintenance procedure follows the "INITIAL SETUP" and gives detailed instructions
for the procedure. These instructions give the part’s general location and name and action
performed. In the example, oil cooler assembly replacement -a. Removal, step 1 is "Disconnect
engine oil cooler supply and return lines (7) from engine oil cooler ports (9)”. Note that the numbers
in parenthesis correspond to the part’s callout number in the accompanying illustration.
NOTE
Warnings, cautions, and notes provide supplemental information:
Warnings

injury, loss of life, loss of life, or long-term health hazard.
Cautions:
Indicate condition, practices, or procedures which must be observed to avoid damage to
equipment or destruction of equipment.
Notes:
Include essential information of special importance, interest, or aid in job performance
which should be remembered and would be otherwise difficult to find or incorporate into the text.
4.
At the end of a procedure, "FOLLOW-ON TASKS” will list those additional tasks that must be
performed to complete the procedure. The Follow-On Tasks for oil cooler assembly replacement are:
Ž Fill oil to proper level (TM 9-2320-280-10).
Ž Install left-hand splash shield (para. 10-17).
Ž Start engine (TM 9-2320-280-10) and check for leaks.
e.
Refer to the example pages for para. 3-8, Engine and Transmission Oil Cooler Assembly Maintenance,
as we review the following points:
1.
Modular Text:
Both pages of text and illustrations are to be used together. This manual was
designed so that the two pages would be visible at once, making part identification and procedure
sequence easy to follow.
2. Initial Setup:
Outlines task conditions.
3. Illustrations:
An exploded diagram of the component shows part locations, attachments, and
spatial relationships. Cutaway views (part of the vehicle is “erased”) show the location and
orientation of screws and attachments.
f.
Your manual is easy to use once you understand its design. We hope it will encourage you to use your
TM more often as an aid to maintenance support for M998 series vehicles.
