TM 9-2320-361-20 10. 11. On page 2-33, 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 VIII is referenced. Turn to the “TABLE OF CONTENTS” and find the chapter dealing with the engine. You find it as “CHAPTER 3, ENGINE AND CLUTCH SYSTEMS MAINTENANCE.” Furthermore, you note that the chapter is divided into nine sections; you are interested in “Section VIII. Exhaust System Maintenance.” NOTE: Before attempting to repair or replace the exhaust system, as a Unit mechanic, you must: 12. 13. 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 re- quired to perform the task, tools needed, and any special notes/requirements necessary. Refer to TM 9-2320-361-20P, Unit Mainte- nance Repair Parts and Special Tools List for M44A2 Series Vehicles, for requisition data concerning replacement parts for this task. Turn to chapter 3, section VIII, which covers “EXHAUST SYSTEM MAINTENANCE.” In the maintenance index we find that there are two paragraphs listed, para. 3-37 and 3-38. Paragraph 3-38 is a task for replacing the exhaust system used only on model M50A2 and M50A3 vehicles. All other M44A2 series vehicles will follow para. 3-37 for replace- ment of the exhaust system. Notice that, in this case, it starts on the same page, 3-82. The first two pages shown have procedures and illustrations for performing the removal steps for components of the exhaust system. vii
