Look at the data plate on your equipment. Write down the modal number and NSN. Look at the cover of each TM. Find the proper model number and NSN. That book is for you. Then look in the section of the Parts Manual under Usable on code. Find the usable on code for your equipment and write it down. When ever looking up parts for your equipment, make sure the Usable on code, (UOC) listed next to the part you are looking up is the same as what you wrote down. I down loaded all the manuals I needed for a generator and then took it to a printing shop. Had it printed out and put in plastic document covers. Makes for BIG books, but if you use them lots, like I did, it was worth it.
