Gearbox bolts for that speciFc howitzer were designed to hold under tremendous
stress—the kind of stress that’s created from the weapon’s heavy recoil. But a handful
of lower-grade bench stock bolts were used instead. These “substitute” bolts sheared
off when the howitzer was Fred.
Plain and simple, this failure was caused by four bolts that weren’t called out in the
parts manual. The end result was a weapon system that was down for the count!
Mechanics, there should be no doubt about what parts to use on Army equipment.
Order and use what’s called out in the TM.
The domino effect is real. Protect yourself, your equipment and your fellow
Soldiers by using the right parts every time.

The Domino EffeCt
A recent parts
failure during
operation of a
towed howitzer is a
real-life example.
like a single domino that starts
a chain reaction, substituting one
part for another grows into a
major problem for youR weapon
or vehicle system.
