HOW TO USE THIS MANUAL This manual is designed to help operate and maintain the CUCV Series trucks. This manual describes in detail the Unit Maintenance prescribed by the Maintenance Allocation Chart (Appendix B) and Source, Maintenance, and Recoverability (SMR) Codes (TM 9-2320-289-20P). FEATURES OF THIS MANUAL: Bleed-to-edge indicators on the cover and on the edge of applicable manual pages provide quick access to chapters and sections most often used. A table of contents is provided for all chapters, sections, and appendices. S, CAUTIONS, NOTES, subject headings, and other important information are highlighted in BOLD print as a visual aid. Statements and words of particular importance are printed in capital letters to create emphasis. Instructions are located together with figures that illustrate the specific task you are working on. In many cases, the task steps and illustrations are located side-by-side, making identification and procedure sequence easier to follow. An alphabetical index is provided at the end of the manual to assist in locating information not readily found in the table of contents. Technical instructions include metric in addition to standard units. A metric conversion chart is provided on the inside back cover. FOLLOW THESE GUIDELINES WHEN YOU USE THIS MANUAL: Quickly read through this manual and become familiar with its contents before proceeding to specific maintenance tasks. A warning summary is provided at the beginning of this manual and should be read before performing any maintenance tasks. In the actual maintenance tasks, follow all S, CAUTIONS, and NOTES. These are given immediately preceding the procedural steps to which they apply. If these instructions are not followed, or care is not taken, you may injure yourself or cause equipment damage. Within a chapter, section, or paragraph, headings are used to help mount the material and assist you in quickly finding tasks. Read all preliminary information found at the beginning of each task. After completing a task, ALWAYS perform the follow-on maintenance at the end of the task. USING YOUR MANUAL: AN EXAMPLE The operator of a CUCV truck complains that the truck engine cranks but will not start. The truck has been assigned to you for repair. To correct the problem you will need to follow these steps: Turn to the cover of your manual. On the right margin, find the listing for Troubleshooting and turn to the page listing given. When you reach the troubleshooting section, locate the paragraph entitled Troubleshooting Symptom Index (paragraph 2-11). Both mechanical and electrical troubleshooting symptoms Troubleshooting Symptom Index and are organized according to are listed in the equipment category. v

Read through the index until you find a symptom listing which most closely matches the problem. The symptom Cranks But Will Not Start is found under the ENGINE category of mechanical troubleshooting. Turn to the page for the troubleshooting procedure that will help solve your problem. Follow the instructions for each Step listed in the troubleshooting procedure. Start with Step 1 and proceed in order until you reach the step where a problem is actually found. In this case, let s assume that steps 1-5 are performed without difficulty, Step 6 reveals that the problem is with the fuel pump. The Corrective Action for Step 6 tells you where in the manual to go to correct the problem: If fuel flow is insufficient, replace fuel pump. (See paragraph 3-10). Paragraph 3-10 is located in Chapter 3. Using the Tab/e of Contents, find the listings for Chapter 3. Because the fuel pump is part of the fuel system, you would proceed to Section II, Fuel System Maintenance. The index at the beginning of Section II will tell you on which page paragraph 3-10 is located, Paragraph 3-10 is the maintenance procedure for replacing the fuel pump. Carefully read through the procedure, follow all instructions, and perform all steps in the proper sequence. When you have finished the last step, you will have replaced the fuel pump, USE OF RTV SEALANT: When maintenance instructions in this manual instruct you to use RTV sealant (Item 41, Appendix C), wait a minimum of 15 minutes before installing the part or assembly to allow the RTV sealant to cure. TRUCKS EQUIPPED WITH SWINGFIRE HEATERS: Maintenance tasks in this manual do not allow for trucks which may have swingfire heaters installed. If the truck you are working on has a swingfire heater, you may have to disconnect the heater s components to obtain access to other components if interference exists. vi
