On page 2-30, step/test relating to resolving
the problem of “Excessive exhaust noise” is
listed:
step 1.
During your inspection, you discover
that an exhaust pipe is cracked and
rusted. The part must be replaced.
Chapter 3, section VI is referenced.
Turn to the ‘TABLE OF CONTENTS” and
find the chapter dealing with the engine. You
find it as "CHAPTER 3, ENGINE SYSTEMS
MAINTENANCE.” Furthermore, you note
that the chapter is divided into seven
sections. You are interested in “Section VI.
Exhaust System Maintenance.”
NOTE:
Before attempting to repair or replace the
exhaust system, as a Unit mechanic, you must:
12.

14.
a. Determine the maintenance responsibility
of repair or replacement of the component.
b. If the task is at your echelon of mainte-
nance 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 TM 9-2320-260-20P, Unit Mainte-
nance Repair Parts and Special Tools List for
M809 Series Vehicles, for requisition data
concerning replacement parts for this task.
Turn to chapter 3, section VI, which covers
"EXHAUST SYSTEM MAINTENANCE.”
In the maintenance index we find that there
are four paragraphs listed.
Paragraph 3-41 is a task for replacing the
exhaust system used only on model M821
vehicles. All other M809 series vehicles will
follow para. 3-40 for replacement of the
exhaust system. Notice that, in this case,
it starts on page 3-76.
The first two pages shown have procedures
and illustrations for performing the removal
steps for components of the exhaust system.
