These elements are not interchangeable. They won’t work right unless they’re used
with their matching housings.
When installing the finned filter element, rotate the element to the left or right
after dropping it into the housing. That lets the element drop snugly over the three
indented circles at the bottom of the housing.
If you forget, the filter element won’t fit right. When you close the clamps, the
pressure cracks the housing. That lets dirty air get through—a sure engine killer.

echanics, when it’s time to change the air cleaner element or housing in an
M113A2 carrier, don’t let your confusion keep the engine from getting the air it
needs.
There are two different air cleaner elements and housings available. If you match
the wrong element to the wrong housing—or vice versa—the carrier’s engine will
spit, sputter and die because it can’t get enough air.
A housing with one circle indented on the bottom is NSN 2940-00-999-2119. The
only filter element that works with that housing is NSN 2940-00-930-2065. It has
no fins and both ends are open.
If you’ve got a housing with three small circles indented on the bottom, it’s NSN
2940-00-103-5797. The element for it is NSN 2940-00-168-2337. It has fins at the
top and is closed at the bottom.
