There’s a TACOM update to the wheel assembly for the M149A2 that’s not shown in WP 0095 or the RPSTL in TM 9-2330-267-13&P (Dec 15). The plain nut, NSN 5310-01-518-7455, shown as Item 1 in WP 0095 is the wrong part and is not to be used. The nut is commonly known as a lug nut.
The TM will be updated to show Item 1 in WP 0095 as the left-hand hexagon plain nut, NSN 5310-00-518-5566, and the right-hand hexagon plain nut, NSN 5310-01-045-3709. Before ordering the hexagon nuts check your water trailer to verify if you need the left-hand or right-hand nuts.
Additionally, Item 7 in WP 0095 will be updated to add the left-hand ribbed shoulder bolt, NSN 5306-00-733-9239. Currently, the TM only shows a right-hand ribbed shoulder bolt. The updated parts are shown here:
