re you one of those mechanics who grabs the Frst screw you can Fnd to reattach the
hull access cover, NSN 5340-00-759-5409, on an M113-series vehicle? Big mistake!
If you grab a screw that’s 2 or more inches long, it’ll hit the transmission oil pan
on A2 vehicles and the transmission casing
on A3 vehicles. Eventually, the screw rubs a
hole and creates a leak.
When the transmission loses enough oil,
the clutches burn up and you’re left with a
vehicle that’s going nowhere.
So make sure you use only the 1

-in
screws, NSN 5305-00-719-5219, that are
called out in ±ig 186 of TM 9-2350-261-
24P and ±ig 186 of TM 9-2350-277-24P.
They hold the access cover in place without
damaging the transmission oil pan or casing.
And don’t forget to include flat washers,
NSN 5310-00-809-5998, when you use the
right screws.
C
rewmen, watch your step when
you’re pulling the air Flter on
your Stryker for cleaning. If you
put those big size 12s in the wrong
place, damage is sure to follow.
Be especially careful of the
coolant reservoir. It can’t hold
your weight. You may not see any
obvious damage, but the inner
seal can crack. That sends all
the coolant to the overflow tank,
resulting in an overheated engine.
